## Appendix B. IRIS FailSafe 2.1.x Software

This appendix summarizes software to be installed on systems used for IRIS FailSafe 2.1.x. It consists of the following sections:

- “Subsystems on the CD”

- “Subsystems for Servers and Workstations in the Pool”

- “Additional Subsystems for Nodes in the FailSafe Cluster”

- “Additional Subsystems for Administrative Workstations ”

| Note: “Install Software” in Chapter 3 contains step-by-step instructions for installing the software.

## Subsystems on the CD

The IRIS FailSafe 2.1.x base CD requires about 10 MB.

Table B-1, lists FailSafe 2.1.x subsystems on the IRIS FailSafe 2.1.x CD.

Table B-1. IRIS FailSafe 2.1.x CD

Purpose | System
--- | ---
IRIS FailSafe 2.1.x | `failsafe2` `failsafe2.idb` `failsafe2.man` `failsafe2.sw` `failsafe2.books` (InSight versions of customer manuals)
FailSafe system administration | `sysadm_failsafe2` `sysadm_failsafe2.idb` `sysadm_failsafe2.man` `sysadm_failsafe2.sw`

Users must install base system administration (`sysadm_base`), cluster administration (`cluster_admin`), cluster control (`cluster_control`), cluster services (`cluster_services`), java (`java_eoe`), and Java Plug-in (`java_plugin`) from the IRIX CD set.

The EL-8+ multiplexer driver subsystems are `el_serial`, `el_serial.man`, and `el_serial.sw`, which are on a CD accompanying the EL-8+ multiplexer.

## Subsystems for Servers and Workstations in the Pool

Table B-2 lists subsystems required for servers and workstations in the pool. The pool is the entire set of servers available for clustering (nodes). It includes servers and the workstation(s) used for administering the cluster

Table B-2. Subsystems Required for Nodes in the Pool (Servers and GUI Client(s))

Product | Images and Subsystems | Prerequisites
--- | --- | ---
Base system administration | `sysadm_base.sw.dso` | None
Base system administration server | `sysadm_base.sw.server` | `sysadm_base.sw.dso`
IRIS FailSafe 2.1.x administration server | `sysadm_failsafe2.sw.server` | `sysadm_base.sw.server` `cluster_admin.sw.base` `cluster_services.sw.cli` `cluster_control.sw.cli` `failsafe2.sw.cli`
Cluster administration | `cluster_admin.sw` `cluster_control.sw` | `sysadm_base.sw.dso`
Web-based administration | `sysadm_failsafe2.sw.web` | `sysadm_failsafe2.sw.client` `sysadm_failsafe2.sw.server` `sysadmbase.sw.client` `java_eoe.sw`, version 3.1.1 Web server
EL-8+ multiplexer driver (from CD included with multiplexer) | `el_serial` `el_serial.man` `el_serial.sw` |

## Additional Subsystems for Nodes in the FailSafe Cluster

Table B-3 lists additional subsystems required for each server that is a node in the cluster. A cluster is one or more nodes coupled with each other by networks. A node is a single UNIX image, usually, an individual server. A node can be a member of only one cluster.

Table B-3. Additional Subsystems Required for Nodes in the Cluster

Product | Images and Subsystems | Prerequisites
--- | --- | ---
Highly available clustering software | `cluster_services.sw` | `cluster_admin.sw` `cluster_control.sw`
IRIS FailSafe 2.1.x software | `failsafe2.sw` | `cluster_services.sw`

## Additional Subsystems for Administrative Workstations

On a workstation used to run the GUI client, you must install subsystems depending on the type of workstation. The following sections provide a list of the subsystems to install on the following:

- IRIX Administrative Workstations

- Non-IRIX Administrative Workstations

### Subsystems for IRIX Administrative Workstations

On a workstation used to run the GUI client from an IRIX desktop, such as IRISconsole, install subsystems listed in Table B-4.

Table B-4. Subsystems Required for IRIX Administrative Workstations

Product | Subsystems | Prerequisites
--- | --- | ---
GUI | `sysadm_failsafe2.sw.client` `sysadm_failsafe2.sw.desktop` | `sysadm_base.sw.client` `java_eoe.sw`, version 3.1.1
Java Plug-in (required only if the workstation is used to launch the GUI client from a Web browser that supports Java) | `java_plugin.sw` `java_plugin.sw32` | Web browser that supports Java

### Subsystems for Non-IRIX Administrative Workstations

From a non-IRIX workstation, the GUI can be launched from a web browser that supports Java.
