Hi,

Go to single user mode.
#init 1
Start SAM and take backup of the systems and data

Hi:

The best insurance for recovering a system (for virtually any reason) is to have a current Ignite recovery tape.

Ignite is designed/intended to recover the operating system (vg00), although other files, directories and volume groups can be included. To create a bootable Ignite recovery tape of vg00, do:

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

Download the latest Ignite software and documentation from here:

http://www.software.hp.com/products/IUX/index.html

For application data, in non-vg00 filesystems, use whatever backup means you wish. In the absence of anything else, I suggest 'fbackup' since you can use graph files to selectively include and exclude files and directories. See the 'fbackup' man pages for more information.

Regards!

You can ignite to recover the system files in a fast manner.

Probably you can ignite the system directories to a tape.

The non-system file systems and user directories can be backed up using regular backup procedures.
SO when a system is down you can use ignite to bring up the system first and then recover the data from the normal backup.

check igniteux at
software.hp.com/IUX

you can use make_tape_recovery for creating a bootable system tape.

Thanks

Hi,

Ignite is the fastest/better way to recover the system ( JRF already explained better)

Anyway, Ignite does not copy from volume group other than vg00. Ignite is really good for OS recovery tapes, but you need something more for full backups (e.g. fbackup) in case you have other volume groups.

Backup issues were discussed many times in these forums. Try searching by keywords fbackup, make_recovery_tape, backup policy.

You can include other volume groups in your make_recovery (ignite) backup tapes should you wish to, however it should be able to fit onto a single tape for portability. This is not something I would readily do unless I am looking after a relatively small size system, that can be backed up to a bootable DLT tape drive. I agree with James. Use a secondary backup program for filesystems other than 'vg00'. There quite a few that can be used.
