## IRIX® 6.5.18 Update Guide

November 2002

Dear Valued Customer,

SGI® is pleased to present the new IRIX® 6.5.18 maintenance and feature release. Starting with IRIX® 6.5, SGI created a new software upgrade strategy, which delivers both the maintenance (6.5.18m) and feature (6.5.18f) streams to our support contract customers. This upgrade is part of a family of releases that periodically enhances IRIX 6.5.

There are several benefits to this release strategy: it provides periodic fixes to IRIX, it assists in managing upgrades, and it supports all platforms. Additional information on this strategy and how it affects you is included in the updated Installation Instructions manual contained in this package. If you need assistance, please visit the Supportfolio™ online website at `http://support.sgi.com` or contact your local support provider.

In conjunction with the release of IRIX® 6.5.15, SGI added to the existing life cycle management categories the Limited Support Mode that customizes services we deliver to our users. This new support mode is targeted for open source products. We now offer eight modes of service for software supported by SGI: Active, Maintenance, Limited, Legacy, Courtesy, Divested, Retired, and Expired.

Active Mode is our highest level of service. It applies to products that are being actively developed and maintained and are orderable through general distribution. Software fixes for all levels of problems can be expected.

Maintenance Mode software is maintained and is still an important part of our product mix. No new functionality is added to products in this support mode. Functional fixes for severe problems are generally available. Products in this support mode category are still orderable through general distribution. Software usually stays in this category about 18 months before being moved to a mode of lesser support.

Limited Mode is a restricted level of service developed mainly for products developed and maintained by open source organizations and that are distributed by SGI.

Legacy Mode software generally runs on out-of-production operating system versions or system platforms that are no longer in active development or maintained. These products are usually distributed with limited availability. New support contracts may be offered and renewed. Services provided with Legacy Mode are limited to providing existing fixes and “workarounds” for reported problems. IRIX® 6.2, IRIX® 6.3, and IRIX® 6.4 operating system revisions are examples of major operating system releases that are supported in this category until January 2003.

Courtesy Mode software is not officially part of the software support offerings. Courtesy mode software is not covered by software support contracts, and call center support is not available. An e-mail alias may be provided to facilitate customer communications and to address any technical questions. Response times will vary according to availability of resources. The e-mail alias may be terminated at any time without advance notice. IRIS Showcase™ and Cosmo Worlds™ are examples of products with Courtesy Mode support.

Divested Mode software has been turned over to a third party who assumes all responsibility for support. SGI no longer distributes these products. Calls received at the SGI Call Center for support on divested products will be redirected to the applicable third party. CA Unicenter® TNG and Syntax TAS™ are examples of divested products.

Retired Mode provides restricted support for older software products which are no longer generally distributed by SGI. This level of support has severe limitations on portability to new platforms. Availability of support at this level is limited to existing customers with whom we have existing contractual obligations. This is the final stage before a product is completely removed from the SGI product set. IRIX 6.2, IRIX 6.3, and IRIX 6.4 operating system versions are examples of major operating system releases that are supported in this category beginning January 2003.

Expired Mode software products have reached the end of their useful life. These products are not supported or distributed in any form by SGI. Examples are: IRIX® 5.3, IRIXPro™, and Proconf.

The webpage at `http://support.sgi.com/irix/news/index.html#swmodes` contains a link to a webpage where the eight software support modes are described in more detail. This webpage also contains links to the latest customer letters, which provide a list of the various software products that have changed support modes. We thank you for your continued commitment to SGI.

Welcome to your SGI IRIX 6.5.18 update. This booklet contains:

- A list of key features in IRIX 6.5.18

- A list of CDs contained in the IRIX 6.5.18 update kit

- A guide to SGI websites

## IRIX 6.5.18 Key New Features

The following changes have been incorporated into the core IRIX 6.5.18 overlay CDs and the Applications CD.

### New Software Features - Feature Stream Only

Filesystems

- XVM snapshot feature
  The XVM snapshot feature provides the ability to create virtual point-in-time images of a filesystem without causing a service interruption. The snapshot feature requires a minimal amount of storage because it uses a copy-on-write mechanism that copies only the data areas that change after the snapshot is created. The XVM snapshot feature is supported in the CXFS and XVM GUIs. For information on the XVM snapshot feature, see the XVM Volume Manager Administrator's Guide, 007-4003-011.

  Use of the XVM snapshot features requires a FLEXlm license.

- CXFS Manager GUI adds XVM GUI functionality
  In IRIX 6.5.18f, the CXFS Manager graphical user interface (GUI) has been enhanced to contain all of the XVM GUI functionality. Using the CXFS GUI in IRIX 6.5.18f or later release, you can view and configure CXFS filesystems as well as use drag-and-drop to structure volume topologies and administer XVM disks. Command buttons provide shortcuts to some tasks.

  For information on the CXFS GUI, see the CXFS Version 2 Software Installation and Administration Guide. For details about XVM volume management, see the XVM Volume Manager Administrator's Guide.

- XVM Volume Manager GUI as a standalone product
  In an environment without cluster services enabled, you can set up and administer logical volumes with the XVM Manager GUI as a standalone product. For information on XVM volume management, see the XVM Volume Manager Administrator's Guide.

- CXFS Supports IRIX Client-Only Nodes
  As of 6.5.18f, IRIX nodes may now be CXFS client-only nodes, meaning that they run a minimal implementation of the CXFS and cluster services, and do not contain a copy of the CXFS cluster database. Client-only nodes are installed with the `cxfs_client` software product.

  Nodes that you want to run as potential metadata servers must be installed with the `cluster_admin` software product, allowing the node to perform cluster administration tasks and contain a copy of the cluster database. They must also be defined as metadata server-capable administration nodes.

  A CXFS cluster is now supported with as many as 32 nodes. As many as 16 of those nodes can be CXFS administration nodes and all other nodes can be client-only nodes. SGI strongly recommends that only potential metadata servers be configured as CXFS server-capable administration nodes and that there be an odd number of server-capable nodes for quorum calculation purposes.

- CXFS relocation disabled; CXFS recovery supported on standby nodes
  In 6.5.18f, CXFS relocation is disabled by default and CXFS recovery is supported only when using standby nodes. This includes recovery (when using standby nodes) of hierarchical storage management (HSM) products using the data management application programming interface (DMAPI).

  A standby node is a metadata server-capable administration node that is configured as a potential metadata server for a given filesystem, but does not currently run any applications that will use that filesystem. To use recovery, you must not run any applications on any of the potential metadata servers for a given filesystem; after the active metadata server has been chosen by the system, you can then run applications that use the filesystem on the active metadata server and client-only nodes.

  Relocation and recovery are fully implemented, but the number of associated problems prevents full support of these features in the current release. Although data integrity is not compromised, cluster node panics or hangs are likely to occur. Relocation and recovery will be fully supported in a future release when these issues are resolved.

  For information on CXFS, see the CXFS Version 2 Software Installation and Administration Guide.

- CXFS upgrade: filesystem definitions
  The structure of the CXFS filesystem configuration was changed with the release of IRIX 6.5.13f. Backward compatibility with earlier versions is no longer maintained as of IRIX 6.5.14f, since all nodes in the cluster must be running the same or adjacent releases.

  - If you are upgrading from IRIX 6.5.13f to 6.5.14f or later, there is no further impact.

  - If you are upgrading from 6.5.12f or earlier, you must perform a one-time manual conversion of your CXFS filesystem definitions.

  See the CXFS Version 2 Software Installation and Administration Guide for more information.

- CXFS upgrade: cluster nodes
  For CXFS customers, if you install IRIX 6.5.18f including `sysadm_base` on a cluster node where the 6.5.13f or earlier version of CXFS is installed, you will need to upgrade to the 6.5.18f version CXFS (`sysadm_cxfs`) and install 6.5.18f `sysadm_cluster`.

### New Software Enhancements - Maintenance and Feature Stream

Filesystems

- Support added for UDF filesystems
  The IRIX 6.5.18 release includes read-only support for the UDF filesystems format typically used for DVDs and packet-written CD-RWs. IRIX support for UDF filesystems does not, however, include support for playing DVD movies. DVDs will be automatically mounted by `mediad` in the same way that CD-ROMs are automatically mounted. For further information on mounting UDF filesystems, see IRIX Admin: Peripheral Devices.

  To determine whether you have a DVD-ROM drive, run `scsicontrol -i /dev/scsi/`scsi-device. The device type will be displayed between the manufacturer's name and the model number.

  Note: Support for UDF filesystems requires that you install `eoe.sw.udf`.

Device Drivers

- QLFC enhanced driver messages
  QLFC has been enhanced to improve its output message format for messages logged to the console and SYSLOG. The name of the driver as it appears in messages has been changed from “QL” to “QLFC”. The syntax of the messages has been modified to include the fabric port number in the message, in a form similar to the manner in which fabric devices are named.

  For example, where the old driver would output this message:

      ql11d(0x200400a0b80cd1ab): target has returned.

  the new driver will output this message:

      qlfc11: 200400a0b80cd1ab/c11p2: target has returned.

Networking/Security

- List approved shells in the /etc/shells file
  In IRIX 6.5.18, the `/etc/shells` file has been added to provide system administrators with the ability to define appropriate shells for users. The implementation of this feature includes the following ramifications:

  A user's shell, as defined in `/etc/passwd` or an NIS map, must be listed in `/etc/shells` for the user to change a password with `yppasswd` or `ypchpass`.

  A user's shell, as defined in `/etc/passwd` or an NIS map, must be listed in `/etc/shells` for sendmail to deliver a user's mail if the user's mail is piped to a process (such as `procmail` or `vacation`).

  Users are able to log in and use the system interactively, regardless of whether the shell is listed in `/etc/shells`. For more information see the `shells`(4) man page.

Hardware Inventory Command

- New hinv command support
  For the IRIX 6.5.18 release, the `hinv` command with the `-v` option displays the PCI/PCI-X bus speed of QLogic fibrechannel adapters. The `hinv -t scsictlr` command displays the SCSI/fibrechannel adapters.

Real-Time

- Processor timer load management
  Beginning with IRIX 6.5.18, a user is able to keep the interrupt and processing load generated by interval timers away from specific CPUs. This feature may reduce latency and jitter for real-time applications. For more information see the `sysmp`(2) and `mpadmin`(1) man pages.

Kernel Tunable Parameters

- Revised reboot_on_panic parameter description
  The `reboot_on_panic` parameter, when set to 1, specifies that the system should automatically reboot after a kernel panic. This is particularly useful for servers or other systems which frequently go unattended or are used remotely, where it may not be convenient to physically reset the system. The default for SGI servers and large graphical systems is to reboot after a kernel panic.

  It is important to note that the rebound variable, an environment variable set in the PROM monitor for most processors, is always checked before the `reboot_on_panic` parameter and can override it. If the `reboot_on_panic` parameter is set to 0 and the rebound value is set to y, the `reboot_on_panic` parameter in effect becomes 1 and your system will automatically reboot.

  For more information, see IRIX Admin: System Configuration and Operation.

Resource Administration

- Job limits support clarified
  Job limit values (`rlim_t`) are 64-bit in both n32 and n64 binaries. Consequently, n32 binaries can set 64-bit limits. o32 binaries cannot set 64-bit limits because `rlim_t` is 32-bits in o32 binaries. IRIX supports three Application Binary Interfaces (ABIs): o32, n64, and n32 (for more information on ABIs, see the `abi`(5) man page). IRIX Admin: Resource Administration, IRIX Admin: System Configuration and Operation, and the `setjlimit` (2) man page have been updated with this information.

Graphic Workstations

- New Falls screen saver
  IRIX 6.5.17 adds a new Falls screen saver that can be selected from the IRIX screen saver control panel. It is an OpenGL depiction of a waterfall.

Checkpoint and Restart

- Enhancements to atcheckpoint() and atrestart()
  At checkpoint time and at restart time, registered functions are called in the same order as the first-in-first-out order of their registration with `atcheckpoint`() or `atrestart`(), respectively. This is an important consideration for applications that need to register multiple callback handlers for checkpoint or restart events.

  Use of `atcheckpoint`() and `atrestart`() now ensures that registered signal handlers are invoked only when a checkpoint or restart of the application is actually in progress (as opposed to the user sending the signals directly via a function such as `sigsend`()).

SGI software product life cycle management

- IRIX support policy
  In accordance with the SGI software product life cycle management strategy announced in November 2000, SGI will announce support mode changes for various software products on a quarterly basis.

### New Software Features-Feature Stream Only

Introduced in 6.5.17

- The IRIX 6.5.17f release includes the XVM Manager GUI. The XVM Manager GUI provides access to the tasks that help you set up and administer XVM logical volumes and provides icons representing states and structure of the XVM volume elements.

- IRIX 6.5.17 includes support for the use of local XVM volumes as FailSafe resources. This requires FailSafe version 2.1.3. XVM volumes used in conjunction with CXFS should not be added as FailSafe resources. For information on configuring FailSafe resources, see the IRIS FailSafe Version 2 Administrator's Guide, 007-3901-006.

Introduced in IRIX 6.5.16

- For the IRIX 6.5.16f release, the `-extend` option was added to the XVM `show` command.

- For IRIX 6.5.16f, CXFS features include the following:

  - Support for multiple operating system (multiOS) clients.

  - I/O fencing.

  - Support for a two-node CXFS cluster running with FailSafe and an L1 controller on Origin 300 and Origin 3200 systems.

- The IRIX 6.5.16f release added the `joblimitsign` group of kernel tunables that can be used to specify that specific job limit resource accumulation and enforcement should be ignored by the kernel.

- IRIX 6.5.16f added the `setjusage` system call, used to update resource usage for jobs in the kernel.

- The IRIX 6.5.16 release removed the `ACCT_FS` parameter in the `/etc/csa.conf` file. The `MIN_BLKS` parameter now determines the minimum number of free 1K blocks needed on the file system on which the `/var/adm/acct` directory resides.

Introduced in IRIX 6.5.15

- For the IRIX 6.5.15f release, the default naming convention for XVM subvolumes in the `/dev/lxvm/` and `/dev/cxvm` directories is volname, subvolume.

- For the 6.5.15f release of IRIX, you can implement disk quotas on XFS filesystems according to group ID. Project and group accounting are mutually exclusive. This feature is on-disk compatible with Linux-XFS group accounting, where this feature is already active.

  Caution: Group quotas are supported in the feature stream only. If you implement group quotas on a disk and, subsequently, mount that disk with the `pquota mount` option on a machine running the maintenance stream or an earlier release of the feature stream on which group quotas are not supported, the quota accounting could be corrupted.

- IRIX 6.5.15f provides the following new features for CXFS.

  - Support has been added for clients of other operating systems such as Solaris as defined in CXFS Client Administration Guide.

  - Default scripts are now provided in the `/var/cluster/clconfd-scripts` directory to permit NFS-exporting of CXFS filesystems listed in `/etc/exports`.

  - Changes have been made to the `rotatelogs` script syntax.

Introduced in IRIX 6.5.14

- The CXFS GUI was enhanced in the IRIX 6.5.14 release.

Introduced in IRIX 6.5.13

- With 6.5.13, the structure of the CXFS filesystem configuration has been changed. CXFS filesystems can now be defined, modified, managed and deleted independently of each other, and of the cluster definition. To accommodate clusters mixing nodes running 6.5.12 and 6.5.13, backwards compatibility is enforced by default in 6.5.13.

- The XVM Volume Manager is used in a clustered environment with CXFS filesystems. The XVM Volume Manager can also be used as a standalone volume manager; this requires that you be running the 6.5.13f release leg of the IRIX operating system or later.

- Added support for the use of mirrors in XVM logical volumes. The mirroring feature of XVM requires the XFS Volume Plexing software option. Customers running CXFS and who want to run mirrors will need to purchase this license. XLV customers with plexing licenses can upgrade to XVM without having to acquire a new license.

Introduced in IRIX 6.5.12

- Supports the labeling of disks as XVM system disks in the XVM Volume Manager. For information on XVM system disks, see the XVM Volume Manager Administrator's Guide.

Introduced in IRIX 6.5.10:

- XVM installed with CXFS is now qualified on IP35 (Origin 3000) systems in addition to the existing qualification on the IP27 (Origin 200, Origin 2000, and Onyx2) and IP30 (Octane) systems.

Introduced in IRIX 6.5.9:

- CXFS supports the use of hierarchical storage management (HSM) products through the data management application programming interface (DMAPI).

- CXFS and IRIS FailSafe 2.1 can be installed and run on the same system, which is known as coexecution.

  Note: The CXFS and FailSafe coexecution feature is not available in the IRIX maintenance stream. IRIS FailSafe 2.1 is an independently shipped product and is not shipped with IRIX.

- Support for the Scheduled Transfer Protocol (STP). For more information, see the `stp`(7P) man page or `http://www.hippi.org`.

- Support for disk quotas that can now be set by project ID.

  For more information on disk quotas and their administration, see IRIX Admin: Disks and Filesystems. For more information on project IDs, see IRIX Admin: Backup, Security, and Accounting. For more information on the administration of disk quotas by project, see the `edquota`(1M), `find`(1M), `quota`(1M), `repquota`(1M), and `fstab`(4) man pages.

- Support for the waitjob feature, which includes the new functions `setwaitjobpid`() and `waitjob`(). For more information, see IRIX Admin: Resource Administration and the `waitjob`(1M) and `setwaitjobpid`(1M) man pages.

Introduced in IRIX 6.5.8:

- Support for Comprehensive System Accounting (CSA). For more information, see `IRIX Admin: Resource Administration` and the csa(1M) man page.

Introduced in IRIX 6.5.7:

- Support for job limits

  Job limits allow system administrators to manage user access to system resources by setting limits on different system usage parameters. For more information on the usage of the different system usage parameters, see the IRIX Admin: Resource Administration Guide and the following man pages: jstat(1), jlimit(1), job_limits(5) genlimits(1M), and showlimits(1).

- Support for the CXFS product

  CXFS provides a cluster file system that allows file sharing between machines. CXFS requires a new volume manager, XVM. The IRIX 6.5.7 release version of CXFS contains metadata server recovery. See the CXFS Version 2 Software Installation and Administration Guide for the administrative shutdown procedures and additional troubleshooting information.

  The Caveat and Release Note Updates link at http://support.sgi.com/6.5/caveat_updates.html should be checked periodically for information on the latest CXFS and XVM patches, descriptions of implemented CXFS and XVM features, updated Release Notes, or any late-breaking caveats.

Introduced in IRIX 6.5.6:

- Support for the Scheduled Transfers (ST) protocol. In this initial release of ST, only the Gigabyte System Network (GSN) network adapter is supported.

Introduced in IRIX 6.5.2:

- Motif 2.1/IRIS ViewKit 2.1

- IRIX Oplock support

- Support for non EUC encoding and locales (`sjis/big5/gbk/utf8`)

### Maintenance and Feature Streams

Introduced in 6.5.17

- With IRIX 6.5.17, the underlying documentation tools and books have undergone a major upgrade. These processes now allow for SGML or XML documents to be published directly into HTML (our delivery format). These same tools are available to you as part of the “SGI Book Building Tools” product; formerly the “IRIS InSight Professional Publisher”.

  For viewing documentation on the IRIX Interactive Desktop, the following changes have been made: InfoSearch (the primary online documentation viewer) has been revamped to support the new document format, SGIHelp (the IRIX Desktop Help system) has undergone minor changes, and the Dynaweb product is no longer shipped (or required). In addition, the IRIS InSight Viewer (insight) now exists solely as an intermediate process that launches your standard desktop web browser to access InfoSearch. Online books can also be viewed using your standard desktop web browser by opening the (local) file: `/usr/share/Insight/library/SGI_bookshelves/index.html`

  Our goal is to deliver all online books to you in this new format. There are circumstances whereby some books may still exist on your local system in the “old format.” Examples would include some of the SGI Developer documentation: the MIPSpro compiler books and the ProDev WorkShop books fall into this category (books that require conversion). The online documentation tools will report a warning when encountering books in the “old format” that require conversion.

  A conversion process is provided (the existing `insightAdmin` command). Various options for performing the conversion are available through this tool. It is important to note that the conversion only needs to be done once, unless additional products are installed that still contain books in the “old format”. Be advised that this process can be time consuming. Total time is based on the size and number of books that need to be converted, and the availability of system resources. On average, 1-3 minutes per book on an older desktop-class machine (R5000 O2) can be expected. For that reason, a system administrator may wish to perform this operation at an off-peak time.

  For further details, see the insight and infosearch release notes, and the related man pages (`insightAdmin`(1), `insight`(1), `sgihelp`(1), `infosearch`(1)). Virtually all SGI documentation can be accessed from `http://docs.sgi.com`.

- In IRIX 6.5.17, the Remote Shell Daemon (`rshd`) has been enhanced to check for expired passwords.

- The overall behavior of the NFS Version 3 client has been modified to improve mixed and heavy load performance. Most casual users of NFS will probably notice little change. However, users should see a marked improvement in performance under the following conditions:

  - Running applications that write large amounts of data over NFS

  - Heavy use of bi-directional NFS I/O

  - Mixed heavy local disk and NFS I/O

  To improve performance under heavy loads, a new set of behaviors have been added that perform the following actions:

  - Enable full-duplex NFS traffic

  - Prevent read and write starvations

  - Provide resource limiting to make the NFS client a fairer user of system resources

  These behaviors are based on the notion of fair scheduling of asynchronous NFS I/O to prevent starvations and provide more efficient use of network bandwidth and server disk resources. This also extends to prevent starvations between different NFS mounted directories.

- IRIX 6.5.17 adds a new `build_cmgr_script`(1M) command that generates a `cmgr`(1M) script from the cluster database. The script can be used later to recreate the cluster database after performing a `cdbreinit`.

- For the IRIX 6.5.17 release, device drivers can create kernel threads not associated with particular interrupts to act as daemons and do background processing.

- For 6.5.17, two new options were added to the `cpuset` command. The `-M` option allows the user to move a process or group of processes and their associated memory from one cpuset to another. The `-T` option allows the user to move a process or group of processes but not their memory from one cpuset to another.

- In IRIX 6.5.17, support for following interfaces has been added:

  - For nodename-to-address and address-to-nodename translations, `getaddrinfo`(3), `getnameinfo`(3), `gai_strerror`(3), `freeaddrinfo`(3), `getipnodebyname`(3), `getipnodebyaddr`(3) and `freehostent`(3)

  - For interface index-to-name and name-to-index conversions, `if_indextoname`(3), `if_nametoindex`(3), `if_nameindex`(3) and `if_freenameindex`(3)

Introduced in IRIX 6.5.16:

- IRIX 6.5.16 supports a new XThread Control Interface (XTCI) that allows users to control many interrupt thread parameters, including cpu binding. For information on this interface, see the `realtime`(5) man page.

- For the IRIX 6.5.16 release, performance improvements have been made to the `rtmond` system monitoring daemon. For information on the `rtmond` daemon, see the `rtmond`(1) man page.

- For the IRIX 6.5.16 release, Array Services scaling support has increased from a maximum of 8 hosts to 64 hosts. Array Services also provides increased interoperability with job limits and new functions such as `askillash`. For more information, see the Array Services release notes and the `array_services`(5) man page and the “Array Services” chapter in IRIX Admin: Resource Administration.

- IRIX 6.5.16 provides support for mice with more than three buttons and mice with wheels. Users with Microsoft Intellimouse or Intellimouse Explorer can use this expanded functionality in many IRIX and Open Source applications. For information on this feature, see the `pcmouse`(7) man page.

- The IRIX 6.5.16 release adds an `-x`[processor] option to the `mpadmin`(1) command that allows you to exclude the specified CPU from performing any work. This functionality is useful in a situation in which you suspect a CPU may have a hardware error but you do not want to shut down your entire system.

  For more information, see the “Excluding a CPU from Performing Work” section in IRIX Admin: System Configuration and Operation and the `mpadmin`(1) man page.

- The IRIX 6.5.16 release includes two new options to the `cpr` command:

  - the `cpr` `-w` option that allows you to use the attribute file located in the current working directory (versus `$HOME/.cpr`).

  - the `cpr-m` memory migration option, which allows you to migrate the checkpointed memory to the location in the system topology where the restart operation is executing. In addition, a

  For more information, see the IRIX Checkpoint and Restart Operation Guide and the `cpr`(1) man page.

- The IRIX 6.5.16 release adds a `CONTENTS` action keyword for the FILE policy of a CPR attribute file. For more information, see the IRIX Checkpoint and Restart Operation Guide.

- The IRIX 6.5.16 release adds two new functions in the Cpuset library called `cpusetMove`(3x) and `cpusetMoveMigrate`(3x). These Cpuset library routines can be used to move processes between cpusets and optionally migrate their memory. For more information on the `cpusetMove`(3x) and `cpusetMoveMigrate`(3x) routines, see Chapter 4, “Using the cpusetMove and cpusetMoveMigrate Functions” in the IRIX Admin: Resource Administration manual and the `cpusetMove`(3x) and `cpusetMoveMigrate`(3x) man pages.

- The IRIX 6.5.16 release adds a `disable_uspollsema_chk` systune variable for the `usopenpollsema`(3P) library call. This variable turns off the standard access mode checking on `usopenpollsema`(3P) (set on the first call to `usopenpollsema`(3P) via the `acc` parameter). Some older IRIX applications that were written to work with `usopenpollsema`(3P) may now require this variable.

  For more information, see the `usopenpollsema`(3P) man page and the `/var/sysgen/mtune/kernel` configuration file.

- The IRIX 6.5.16 release adds documentation for the following kernel tunable parameters:

  - `min_bufmem` general parameter

  - `rtcpus` dispatch parameter

  - `bdflush_interval` filesystem parameter

  For more information on kernel tunable parameters, see Appendix A in IRIX Admin: System Configuration and Operation.

- IRIX 6.5.16 provides support for upgrading `license_eoe` to the FLEXlm 8.1a release from Globetrotter Software, Inc. The license manager daemon is built in V5 compatibility mode. For more information see the FLEXlm End User Manual and the associated man pages.

  IRIX 6.5.16 also provides support for upgrading `license_dev` to include new optional thread-safe FLEXlm 8.1a client side libraries and headers. For more information see the `license_dev` release notes.

Introduced in IRIX 6.5.15:

- XFS inode numbers are 64-bit values containing an encoded disk location. For large filesystems (1 terabyte plus), the inode numbers can overflow into the top 32 bits of the number. Certain backup applications which use the inode number only allow 32 bits of space, and thus have severe problems dealing with very large XFS filesystems.

  As of IRIX 6.5.15, XFS has been changed to allocate inodes only within the lower portion of the filesystem to avoid this overflow issue. Other allocation policies in the filesystem will make this lower order space preferred for inodes and reduce the risk of a filesystem refusing to create new inodes when it still has space available.

  For existing large filesystems with high numbered inodes this does not solve the problem, but it does solve it for new filesystems, and for new files created on existing filesystems.

  For backwards compatibility a new mount option is available, inode64, this will allow xfs to place inodes anywhere in the filesystem and follow exactly the original placement policies. Filesystems which were small enough not to be able to overflow 32 bits of inode number also retain the old behavior.

- The 6.5.15 release of IRIX adds support for disks that have a capacity of 2 terabytes. Previously, the maximum was 1 terabyte.

- For the IRIX 6.5.15 release, Chapter 5 “System Administration in a Multiuser Environment” in IRIX Admin: System Configuration and Operation has been updated with a new section on Project ID numbers and the `chproj`(1) command that changes the project ownership of a file.For more information, see the `chown`(1) man page and the IRIX Admin: System Configuration and Operation manual.

- In IRIX 6.5.15, the systune parameter `gang_sched_off` is turned on by default. This means that gangs will not be running on the system unless the system administrator sets `gang_sched_off` to 0. This differs from previous IRIX releases, for which gangs ran on the system automatically.

  This change has been made per field request because we have discovered that having gang scheduling on by default greatly diminishes system performance. Most customers have been running with it off.

- The IRIX 6.5.15 release adds a coremask parameter set in the `/var/sysgen/mtune/kernel` file to determine what kind of permissions a core file will receive. Currently, when a process creates a core file, it uses the umask of the owner of the process to determine the permissions. This can lead to core files containing sensitive information being created with world readable permissions. This systune variable allows the system administrator to limit access to core files. The default is 0, which is the current behavior. However, if the coremask variable is set to some other value, it uses that number as the umask and ignores the umask of the owner of the process. For example, if coremask is set to 0177 and the owner of the process has a umask of 022, the permissions set on the core file will be 600 instead of 644. This variable assumes that the number entered is octal. The default setting is 0. The minimum setting is 0. The maximum setting is 0177.

  For more information on the coremask parameter, see Appendix A, “IRIX Kernel Tunable Parameters”, in IRIX Admin: System Configuration and Operation.

- A new partitioning administration command, `partmgr`(1M), is available to define and store partition definitions. For more information, see IRIX Admin: System Configuration and Operation.

- The IRIX 6.5.15 release adds support for the `/dev/poll` interface for scalable and efficient event notification. For information on `/dev/poll`, see the `poll`(7M) man page.

- For the IRIX 6.5.15 release, the DHCP client (`proclaim`) has been updated to include options to allow DHCP clients to capture changes to DNS, NIS, or GATEWAY in your environment. For more information, see the `proclaim`(1M) man page and IRIX Admin: Networking and Mail.

- The IRIX 6.5.15 release provides the ability to designate one or more CPUs or a range of CPUs on a single line in the `cpuset` configuration file. The CPUs in a `cpuset` configuration file do not have to be specified in a particular order. For more information on the `cpuset` configuration file, see Chapter 4, “Cpuset System”, in IRIX Admin: Resource Administration.

- For the 6.5.15 release, the `systune`(1M) man page has been updated to describe a situation where the system segment size value (`syssegsz`) reported by the `systune` command is different than the value set in the `/unix` file.

- Starting with the IRIX 6.5.15 release, each partition of a partitioned Origin 3000 system will have a new unique FLEXlm host ID (`lmhostid`). Any FLEXlm license based on the old non-partitioned `lmhostid` value will no longer work and a new license key must be generated. See the following webpage for additional details: `http://www.sgi.com/support/licensing/`.

  - Contact the applicable software product vendor and provide the `lmhostid` number of the partition to generate a new license key. For nodelock licenses, provide the `lmhostid` for all partitions of the software installed and operating.

  - For software licensed by SGI, see the following webpage for more details: `http://www.sgi.com/support/licensing/`.

  - For e-mail and telephone contact information, see the IRIX 6.5.16 Welcome page and follow the “Bundled software and licenses” link.

- For IRIX 6.5.15 we added HOTPLUG attach and detach support for SGI Gigabit Ethernet Network adapters. This feature is supported on IP35 Origin 3000 series systems only; it is not supported on IP35 0300 systems. For information on this feature, see IRIX Admin: Networking and Mail.

- The IRIX 6.5.15 release supports the `lmparthostids` and `lmbasehostid` commands.

Introduced in IRIX 6.5.14:

- In the IRIX 6.5.5 release, SGI introduced a new optional directory format for XFS filesystems, referred to as the "version 2" directory format in `mkfs` output.

  Beginning with the IRIX 6.5.14 release, version 2 directories of XFS will be the default for all new filesystems created with `mkfs`.

  Version 1 directory filesystem creation will still be supported, but this will require that you specify the `-n` `version=1` parameter of the `mkfs` command.

  SGI recommends that all new XFS filesystems be created with version 2 directories. IRIX releases older than IRIX 6.5.5, however, will not be able to mount a filesystem created with a version 2 directory and will issue the following message when a mount is attempted:

  Wrong filesystem type: xfs

  There is no means for converting a filesystem, in place, between version 1 and version 2 directories. A filesystem can be converted between version 1 and version 2 directories by means of an `xfsdump`/`mkfs`/`xfsrestore` sequence.

  For more information, see `IRIX Admin: Disks and Filesystems`.

- A`-q` cpuset_name `-p` option was added to the `cpuset` command that allows you to see the properties of particular cpuset, such as, the number of processes and CPUs associated with the specified cpuset.

- The `cpusetGetProperties()` and `cpusetFreeProperties()` functions were added to the Cpuset System library. For information, see chapter 4, "Cpuset System", in the IRIX Admin: Resource Administration manual and the c`pusetGetProperties`(3x) and `cpusetFreeProperties`(3x) man pages.

- Parts of the IRIX Interactive Desktop were refreshed in IRIX 6.5.14.

Introduced in IRIX 6.5.13

- Improved exit codes for the `xfsrestore` and `xfsdump` commands.

- Changed the `mkfs` command to allow you to specify the size of an XFS allocation group, as an alternative to specifying the total number of allocation groups. For information, see the`mkfs_xfs` man page and IRIX Admin: Disks and Filesystems.

- Changed the `mkfs` command to allow you to specify the size of a stripe unit and the size of a stripe width in bytes or in filesystem blocks, as an alternative to specifying these values in 512-byte block units. For information, see the `mkfs_xfs` man page and IRIX Admin: Disks and Filesystems.

- Changed the default size of an XFS allocation group; larger filesystems will result in larger default allocation group sizes.

- The`xfsdump` and `xfsrestore` commands will provide the VSN of the tape that reached its end-of-volume (or the VSN of a new tape that needs to be mounted) and pass this VSN to the `media_change_alert_program` specified with the `-c` option. This lets system administrators send commands to a tape jukebox to mount the next tape.

- Changed the default size of an XFS log. The default log size grows with the size of the filesystem up to the maximum log size, 128 megabytes, on a 1 terabyte filesystem. For information on the default values of XFS allocation groups and XFS log sizes, see IRIX Admin: Disks and Filesystems.

- Added `cpusetAttachPID()` and `cpusetDetachPID()` functions to the Cpuset System library. For information, see chapter 4, "Cpuset System", in the IRIX Admin: Resource Administration manual and the `cpusetAttachPID`(3x)and `cpusetDetachPID`(3x) man pages.

- The following features have been moved from Enhanced DHCP to standard DHCP:

  - Ping check before an address is leased to insure it is not already in use

  - MAC address filtering; clients whose MAC address is listed in a file will be unable to obtain a lease and/or accesses from these clients will be logged.

  For more information, see the `dhcp_bootp` man page.

- Added implementation of End Sequence to Scheduled Transfer Protocol. The upper layer protocol or applications can now terminate a transfer and restart another one without taking down virtual connection.

- VPro for Octane and OpenGL performance improvements.

- The following new system controller features have been implemented for the SGI Origin 3000 server series:

  - Enabled router port security, which prevents unauthorized enabling of additional router ports on router bricks in the SGI Origin and Onyx 3400 server series

  - Enabled system serial number security, which prevents unauthorized changes to the system serial number

  - Completely redesigned the graphical interface for the front-panel display of the SGI 3400 and 3800 servers

- Added hotplug attach feature that allows Gigabit Ethernet cards to be installed on a running system. For more information, see the `pciconfig` and `ifconfig` man pages.

- Added Origin 3000 system partitioning support in the `eoe.sw.partition` software package. This feature improves how system partitioning software is installed, enabled, and disabled. It also eliminates the need to manually edit configuration files.

- Efficiency improvements have been made to the BTE driver layer to reduce both latency and contention. This feature is a performance improvement to the existing functionality that is used internally by the system.

- The tools that report CPU utilization have been modified to correct the sampling of %WIO to omit idle time in line with industry standards. See the `sar(`1) man page for details.

Introduced in IRIX 6.5.12

- OpenGL Performer 2.4.1 execution environment

- The IRIX tape-support feature consists of a tape support driver, personality daemons, and a daemon that manages the personality daemons.This release supports various devices including the Fibre Channel implementation on the StorageTek 9840 and T9940A tape drives. The `reserve`, `release`, `preempt`, `clear`, and `prsv` commands are available for these tape drives on the `mt` command. For more information, see the `mt`(1), `tsarchive`(1M), `tsdaemon`(1M), `tserrpt`(1M), `tsset`(1M), `tsstop`(1M), `ts.config`(4), and `ts`(7) man pages.

- The Scheduled Transfer Protocol (STP) has moved from the feature stream to the maintenance and feature stream. STP is now a mature supported protocol and it includes TRIX support.

Introduced in IRIX 6.5.11:

- Support for the use of a reserved area of memory; this reserved area is between virtual addresses 0x30000000 and 0x40000000. This feature disables the reserved area of memory that the kernel provides for applications to place their mmap and shmat mappings. For more information, see the `mmap`(2), `shmat`(2), `syssgi`(2), and `sgi_use_anyaddr`(1) man pages.

- Support for weightless pthreads; they allow you to lower the priority of a process by using the `npri -w` command. For more information, see the `npri`(1) man page.

- Support for an increased maximum number of logical unit numbers (LUNs) in the SCSI infrastructure from 64 to 255. This change impacts only the fcadp and qlfc fibre channel drivers and they will now enforce this LUN limit. If a LUN is greater than 255, it will be ignored after issuing a message to this effect. If you use large numbers of LUNs, you can exhaust the hardware graph. You may need to use the `systune` command to increase the hwgraph_num_dev parameter to let the kernel build larger hardware graphs.

- Support for licensing of partitioned environments. For more information, see IRIX Admin: Software Installation and Licensing.

- Support for the PCI Hot Plug infrastructure on the SGI 3200, SGI 3400, and SGI 3800 servers.For more information, see the `pciconfig`(1) man page for specific administrative options.

- Support for new Miser cpuset options. These options allow the creation of restrictive memory pools from the nodes that contain the CPUs listed in the configuration file.For more information on these options, see the cpuset(4) man page.

- OpenGL Performer Runtime 2.2.8 overlay incorporates the latest fixes.

- Documenter's Workbench with the latest Y2000 bug fixes can be installed from the /CDROM/dist/unbundled directory of the IRIX 6.5.8 (or above) Overlays CD (2 of 3), May 2000.

Introduced in IRIX 6.5.7:

- Updating `sendmail` to version 8.9.3

  The version of the IRIX sendmail mail system supplied on this release and previous IRIX 6.5.x releases is based on `sendmail` version 8.8.8. Due to customer demand, the current sendmail.org release, `sendmail` version 8.9.3 (see http://www.sendmail.org), will be supplied via patch 3865 or its successor. SGI intends to support `sendmail` 8.9.3 (or above) as the standard released `sendmail` in a future IRIX release, target 6.5.10.

  For more information on the 8.9.3 version of `sendmail`, see the IRIX Administration: Networking and Mail Guide provided with the patch. For more information on how to configure `sendmail` 8.9.3, see http://www.sendmail.org/m4/readme.html.

- Open Inventor Runtime 2.1.6 overlay incorporates fixes included in versions 2.1.4 and 2.1.5. This overlay requires that the base Inventor 2.1.4 image be installed already, or with the overlay during the same install session. The Inventor 2.1.6 overlay can be installed on IRIX 6.5.5 and later.

### Documentation changes

Manuals in the IRIX Admin document set are updated when necessary to document new features at each IRIX release. The front of each manual includes a description of new features and major documentation changes for the current revision, as well as a record of when the manual was revised. The most recent version of an IRIX Admin document available on the Technical Publications Library includes information for features available in the current IRIX release.

The Techpubs Library is available at: `http://docs.sgi.com`.

### Applications CD changes

| Note: Applications take two forms: full images and overlays. The base versions of each can be found on the Applications CD. When full images are updated, new versions are placed on the Applications CD. Upgrades of overlay products, however, are located on the Overlay.
