You should install the software for your Silicon Graphics Octane2 Duo upgrade before you install the hardware. After the software and hardware are installed, Chapter 5, “Configuring the System and Verifying Installation” provides system setup and verification instructions.
The software installation process for the Duo upgrade consists of the following steps:
Verifying your IRIX version
Performing a system backup
Backing up the Xserver file and enabling the Duo software
Note: Read any release notes included with your upgrade kit before installing the software to learn of any last minute changes.
To verify the version of the IRIX operating system installed on your Octane2 system, follow the instructions in this section.
From an IRIX command prompt, type:
1% uname -R |
You will see output similar to the following:
6.5 6.5.13f |
Depending on your version, go to one of these sections: “IRIX 6.5.13 or Earlier”, “IRIX 6.5.14”, or “IRIX 6.5.15 or Later (When Available)”.
If you system has IRIX version 6.5.13 or earlier, you will need to upgrade your system to IRIX 6.5.14 with patch 4426, or IRIX 6.5.15 (when available), before installing the Duo hardware. Contact your SGI representative for more information.
If you system has IRIX version 6.5.14, you will need patch 4426 before installing the Duo hardware.
To determine if you have patch 4426 installed, type the following at an IRIX command prompt:
2% versions patchSG0004426 |
If the output of this command is simply the headings “Name,” “Date,” and “Description” you do not have patch 4426 installed. This patch must be installed (or you must upgrade your system to IRIX 6.5.15 or later, when released) before installing the Duo hardware.
If the output of this command includes items below the Name-Date-Description heading, you do have patch 4426 installed, and you may install the Duo hardware.
It is always a good idea to back up your system before installing any new hardware. If you have not backed up your system recently, take this opportunity to do so. For instructions on backing up your system, see the Personal System Administration Guide.
After ensuring that you are running an appropriate version of IRIX, you must back up the original Xserver file, enable the Duo software by installing a new Xserver file, and replace the default login screen.
Follow these instructions:
From Toolchest > Desktop, select Open UNIX Shell.
Become superuser by typing su.
At the prompt, type:
cp /var/X11/xdm/Xserver /var/X11/xdm/Xserver.orig
At the prompt, type:
cp /var/X11/xdm/Xserver.2key /var/X11/xdm/Xserver
At the prompt, type:
chkconfig visuallogin off
Type exit to exit superuser mode.
Restart the system. The new login screen appears.
Proceed to Chapter 3, “Octane2 Duo Upgrade Hardware Installation” to begin installing the hardware.
