Re: Backup OS before upgrade
Yes, the recommended backup of the OS is by using a make_tape_recovery, have a look at the Ignite software link.
Ignite creates a bootable image on tape or the network.

Re: Backup OS before upgrade
This will allow us to restore the backup in case if the server panics or doesn't come up after upgradation or patch installation
Syntax:
Install Ignite-UX product as provide above
# make_tape_recovery -v -x inc_entire=vg00 -a /dev/rmt/Xmn
Replace Xmn by tape device
To get the tape device
# ioscan -fnC tape
The above make_tape_recovery will take the backup only the filesystem which belongs to vg00. It is always advisable to take the backup of only OS filesystem via Ignite, since system restoration times reduces drastically.
You could take the other non-OS filesystem backup via fbackup, tar or any other backup utilities.
Please assign points.

Re: Backup OS before upgrade
The Ignite recovery tape is one recommendation, of course. If you think the patch process, you need to have not only your kernel in sync with various libraries, but you certainly want your IPD (Installed Product Database as described by the '/var/adm/sw' directory contents) in line with the various files in '/usr', /opt', '/etc' and '/sbin'.
Thus trying to guess what you should backup and/or restore is foolhardy.
If you are running 11.23 or later, you should look at DRD as another strategy:

SolutionIf the tape drive is supported for boot:
make_tape_recovery -v -x inc_entire=vg00
If note: make_net_recovery
Direct the output to an NFS share.

Re: Backup OS before upgrade
1) ignite (to tape or network)
2) use DRD (dynamic root disk)
3) shutdown OS and remove a mirrored disk, boot in quorum mode. After checking that all patches working, insert the disk again and sync the mirror (caution with boot loader patches!) - less preferred
Hope this helps!

Torsten.

Re: Backup OS before upgrade
Boot the install DVD and select the "restore from tape" option.
Just put the tape into the drive before. ;-)
Hope this helps!

Torsten.
