HP-UX recovery

how to recovery HP-UX from disaster?

[Geoff Wild]

Depends...

Did you use an ignite tape or server?

If neither - did you backup the server at all?



For ignite:

See chapter 9

Hi,

Ignite is the wonderful tool of OS recovery in HP Ux. It recovers your system from a scratch within few hours & not requiring minimal reconfiguration. But you need to restore application backups if the disks having those were also disturbed.

You can recover your HPUX via daily/weekly make_tape_recovery tape or from Ignite make_net_recovery image server, for more information you can check,

#man make_tape_recovery
#man make_net_recovery

these are for base OS environment, the SA should made the backup os tape in specific period for preventing future require.

if the metadata need to recover, or backup, you can try 'fbackup' and 'frecover'

This is a pretty open ended question.

It starts with system design
How solid is the sytem design?
Are the disks mirrored?
Is On-Line JFS installed?
Do you have multiple Network cards?
Are you using Seviceguard?
Have you kept VG00 just for the OS,and not added application code to it?
Have you run vgcfgbackup against all of the VG's?

Do you perform regular backups?
make_tape_recovery/make_net_recovery of VG00 at least weekly
backups of the the rest of the vg's nightly. Are the tapes moved to off site storage daily?

do you have a backup server to restore to?

That being said, the steps could be:
start with a working server - either one that has bee repaired/replaced or at a disaster recovery site.

boot off of the install/recovery CD.

Point the recovery program to either the make_tape_recovery tape or the ignite server containing the make_net_recovery file

reinstall the OS

recreate your VG's (hopefully with vgcfgrestore)

import the data disks - if they were not destroyed

restore data from tape, if the orignial data disks were distroye, or not available
