Steps to install IRIX 6.5.X from Scratch:
1. Backup your existing system disk
2. Reformat and exercise the drive (Optional but recommended by Discreet Logic Technical Support )
3. Install IRIX 6.5.X
4. Setup the network information
5. Load setup files from the system disk backup
Step 1: Back up your system disk
It is very important that you backup your System Disk because when you install IRIX 6.5.X, you will lose all information currently stored on it. It is recommended that you do the two following steps:
A. BACKUP: When you install IRIX 6.5, you will lose all of the data on your system disk. Use the Backup command to make a tape backup of entire system. You should backup:
1. Login as root
2. Determine the SCSI controller number and device unit number of the tape drive from the hardware inventory. Type:
hinv | grep Tape
The hardware inventory “ hinv ” line for the tape drive appears, and looks similar to:
Tape drive: unit 2 on SCSI controller 0: DAT
3. Command to backup the entire system disk.
Backup –t /dev/mt/tps<controller#>;d<device#>;ns –i /
Where <controller#>; and <device#>; are the SCSI controller and device unit numbers you determined above from the hinv command.
B. TAR file: The setup files from the /usr/discreet home directory, the logical volume table (/etc/lvtab) if you are using a DL disk array, and any other files, software applications, and so on, that you want to keep and restore quickly.
1. Log in as root.
2. Determine the SCSI controller number and device unit number of the tape drive from the hardware inventory. Type:
hinv | grep Tape
