SYSTEM RECOVERY USING IGNITE-UX

Oh no, your root disk just crashed and you have no backup in place. Shame on you. Not having the time is no longer an excuse. Using two tools within the FREE Ignite-UX package, you can create and recover VG00 in a relatively short time. The steps are as follows:

1. Download and install Ignite-UX from
< www.software.hp.com >

2. Insert a tape into your tape drive (/dev/rmt/0m) and run following command while the system has little or no activity. You might need to specify the full path leading to the command.

# make_tape_recovery -A

This is a newer command. It used to be "make_recovery -AC". The command uses /dev/rmt/0mn as the default tape device for making the recovery tape. This command backs up every file in the root disk/volume vg00 and later make it possible to use the check_recovery command, to see how much has changed on the system since the tape was made.

3. Ensure that you have a good full backup of your system. The make_tape_recovery utility was not designed to replace standard backup procedures for all your data files.

4. Review the log files:
/var/opt/ignite/logs/makrec.log1 #Logs progress reports
/var/opt/ignite/logs/makrec.log2 #Logs an Index of filesets stored on tape

In the event of a catastrophic failure of your root disk(s). Use the following procedure to recover:

1. Replace the disk(s)

2. Insert latest make_tape_recovery tape into the tape drive and boot the system.

3. Interrupt the boot process, initiate a search and boot from your tape drive.

Main Menu: search ipl
Main Menu: boot scsi.#.0

4. Don't interrupt the recovery process. Allow the recovery process to continue non-interactively.

5.Once the system boots (approx 1-2 hrs, depending on archive size), recover latest backups.
