- “Accessing the SGI BIOS Setup Utility”

- “Enabling BaseIO VGA”

- “Booting Using iSCSI Protocol”

## Enabling a Remote Console

This section describes how to use KVM to enable remote console access.

| Note: Remote console is now available and is in BaseIO BMC firmware versions 1.2.2 or later. The node BMC firmware and the BaseIO BMC firmware typically have different version numbers. Make sure the BaseIO BMC firmware is 1.2.2 or later to have the remote console capability.

Procedure 3-1. Enabling a Remote Console

| Note: Make sure your workstation has Java 6 (Java 1.6.0 or later). You can also use a VNC viewer or similar remote desktop to make sure you get Firefox running on the SMN and not running on your local system.

To enable a remote console to your SGI Altix UV system, perform the following steps:

1. Establish a network connection to the SMN, as follows:

       # ssh -X sysco@uv-system-smn

   The password set out of the factory is `sysco`.

2. From the SMN, launch the Mozilla Firefox web browser, as follows:

       sysco@system-smn:~/hw>firefox -no-remote

3. Enter the IP address of the BaseIO node baseboard management controller (BMC), similar to the following:

       http://192.168.1.200

   To determine the IP address of the BaseIO node BMC, see “Determining the IP Address of the BaseIO BMC”.

4. The BaseIO node BMC login screen appears, as shown in Figure 3-1. Login as `root` with the password `superuser`.

    | Note: You may need to expand the JViewer window in order to see the entire desktop of the system in the following steps.

12. From the Shell> prompt issue the following commands, as shown in Figure 3-9:

        Shell>fs0:
        fs0:\>cd efi
        fs0:\efi>cd SuSE
        fs0:\efi\SuSe>elilo

## Changing Configuration Settings

From the Configuration tab shown in Figure 3-13, you can access various configuration setting pages. For example, you can configure fixed network settings under the Network Settings page.

Under the Mouse Mode Settings page, the Absolute setting should be selected for both Linux and Windows operating systems on the host. Older Linux distributions required Relative mouse mode. SGI Altix UV systems use Absolute mouse mode.

The remainder of the configuration pages are security related and may be of use to you if you connect the BaseIO BMC to your house network rather than the system management node.

## Reinstalling the Operating System on an Altix UV System

This section describes how to use virtual media redirection to mount a CD-ROM or ISO image from the system management node (SMN) and use it on your Altix UV 100 or Altix UV 1000 system to reinstall the operating system.

Procedure 3-2. Reinstalling and Booting the Altix UV 100 or Altix UV 1000 Operating System

To reinstall and boot an Altix UV 100 or Altix 1000 system using remote media, perform the following steps:

1. Bring up the KVM (JViewer) client on the BaseIO BMC (see “Enabling a Remote Console”).

2. To specify an ISO image file to redirect to the Altix UV operating system ISO image, select Device-> Redirect ISO on the JViewer client, as shown in Figure 3-14. Then select the ISO image file to use, as shown in Figure 3-15. If you are using physical media, to redirect a CD-ROM or DVD, place the CD in the drive of the machine where JViewer is running, then select Device-> Redirect CDROM on the JViewer client, as shown in Figure 3-16.

3. When the system gets to the EFI prompt, enter `exit` to get to the BIOS setup screen, as shown in Figure 3-17.

   Figure 3-17. KVM JViewer Shell Prompt Screen

4. From the BIOS setup utility, select Boot Manager , as shown in Figure 3-18.

   Figure 3-18. Device Manager Boot Manager Selection

5. From the Boot Manager screen, select EFI USB Device, as shown in Figure 3-19.

   Figure 3-19. Boot Manager Screen

6. The ELILO boot manager starts executing, as shown in Figure 3-20.

   Figure 3-20. ELILO Boot Manager

   When using the SLES install DVD, the installer will boot without any further intervention.

   | Note: Due to a software bug or mismatch between the X configuration software on the SLES install DVD and the KVM viewer, mouse tracking in the install screens does not work well. You can use the `Enter` key, to select the Next button and use the arrow keys to move back and forth on each screen.

7. When using the RHEL install DVD, manual intervention is required to allow the install to boot.

   Shortly after selecting "EFI USB Device", the KVM screen will give a countdown with a "press any key to see menu" type of message. Enter a key, which will take you to the RedHat grub menu. With the first menu selection highlighted, press 'e', which will allow you to edit the boot options. This brings up a new screen, where the first line starts with 'kernel'. With this line selected, press 'e' again, and enter "virtefi " at the end of the line. Press Enter, which will return you to the previous menu. Then press 'b' to boot the configuration. The RedHat graphical installer will then start.

## Determining the IP Address of the BaseIO BMC

This section describes how to determine the IP address of the BaseIO BMC.

By default, the external Ethernet port on the BaseIO BMC is configured to use DHCP. In the case that it is connected to an SMN, the SMN will serve it an IP address mapped to a known host name.

Procedure 3-3. Determining the IP address of the BaseIO BMC without an SMN

To determine the IP address of the BaseIO, perform the following steps:

1. Login to the CMC, as follows:

       ssh root@hostname-cmc
       SGI Chassis Manager Controller, Firmware Rev. 1.1.11

       CMC:r1i1c>

2. Run the `iodcon` command on the CMC to get to the BaseIO BMC' `ibmc0`, as follows:

       uv14-cmc CMC:r001i01c> iodcon

   The `iodcon` tool brings up an internal serial connection to the BaseIO BMC (it is serial, which is why you need to hit `ENTER` to see the prompt in the next step).

   Press the `Enter` key to get the `r001i01b00i>` prompt

3. Run the `ifconfig` `eth1` command to obtain the `inet` `addr`, as follows:

       r001i01b00i> ifconfig eth1
       eth1      Link encap:Ethernet  HWaddr 08:00:69:15:C0:57
                 inet addr:172.20.255.254  Bcast:172.20.255.255  Mask:255.255.0.0
                 UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
                 RX packets:1508779 errors:204 dropped:28 overruns:0 frame:204
                 TX packets:2262923 errors:0 dropped:0 overruns:0 carrier:0
                 collisions:0 txqueuelen:1000
                 RX bytes:924130317 (881.3 MiB)  TX bytes:3017177156 (2.8 GiB)
                 Interrupt:1

4. Enter `CTRL-X` to exit the console.

5. The output also displays the MAC address as the `HWaddr`. You can use this information to configure a known MAC to IP address/host name mapping in your DHCP server.

Procedure 3-4. Determining the IP address of the BaseIO BMC with an SMN

To determine the IP address of the BaseIO, perform the following steps:

1. Establish a network connection to the SMN, as follows:

       # ssh -X sysco@uv-system-smn

   The password set out of the factory is `sysco`.

2. Perform the following command to find the IP address of the BaseIO BMC, as follows:

       sysco@uv14-smn:~/hw> cmclist -a
       sysco@uv14-smn:~/hw> cmclist -a
       # File: /var/lib/dhcp/db/dhcpd.leases
       # UID              IP Address
       d \001\010\000i\025\300W 172.20.255.254
       sysco@uv14-smn:~/hw>

## Accessing the SGI BIOS Setup Utility

This section describes how to access the SGI BIOS setup utility software residing on the BaseIO blade using the KVM (JViewer) window. This is the same BIOS setup utility that you can access using the text-based `console` (formerly, `uvcon`) command.

Procedure 3-5. Accessing the SGI BIOS Setup Utility

To access the SGI BIOS setup utility software, perform the following steps:

1. Perform steps one through 11 in Procedure 3-1.

2. When the Linux Shell> prompt appears enter exit, as shown in Figure 3-21.

   Figure 3-21. KVM JViewer Shell Prompt with `exit` Command Screen

3. The SGI KVM screen appears, as shown in Figure 3-22.

   Figure 3-22. SGI KVM Console Startup Screen

   After the SGI KVM Console software completes loading, the BIOS setup utility appears, as shown in Figure 3-23.
