Hi,
the easiest way is to use SAM.

Hi,

one possibility is 'sam'.
Choose the 'Backup and Recovery' area - 'Interaktiv 'Backup and Recovery'.
Mark the hardware and choose under 'Actions' 'Recovery'.

Under 'Additional Parameters' you can set if files are placed from where they are or in another directory. Also you can select the recovery scope, i.e. if you want all file from the tape or special ones.

Hello ,
Thanks for the reply . Actually i have backed up the vg00 and i was trying to restore OS.
please advice.

Hi,

have you asked yourself to use ignite for restoring a complete OS?

Otherwise you have to install UX, create the same vg00 you have on the other ws and write back the content of the tape.
But I don't know if you can rewrite the /dev file over which your just recover your tape.

If you make tests only, then you can try.
Other possibility - you write back on a second disk and then use this disk for boot.

But much better is using ignite ...

/opt/ignite/bin/make_tape_recovery -Av -d /dev/rmt/0m .

Just boot from the tape. If you doesn't interrupt the boot process, the system will be restored like the original (without the mirrored disk).

If you interrupt, you can change the settings, like file system sizes.

It may be helpful to write down the hardware path to the tape, e.g. 0/1/2/3.4.0

So you can boot quickly without searching the boot device:

Main Menu: Enter command or menu > boot 0/1/2/3.4.0
Do you wish to stop at the ISL prompt prior to booting? (y/n) >> n

Thanks Much

You can check your backup from a running OS:

# mt -f /dev/rmt/?mn rew
# mt -f /dev/rmt/?mn fsf 1
# tar -tvf /dev/rmt/?mn


Just in case you have an Integrity server, the restore procedure is a bit different:

You have to boot the installation DVD, select

-> Install HP-UX -> select Advanced Installation -> Recovery tape -> GO!

Hi,

interrupt boot process and search for the bootable tape device.

As you can read here:
http://www5.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000079988350

you don't have used the option you wanted to:
in make_tape_recovery '-d' is an archive description not the destination - neverthless I think your command worked because dev/rmt/0m is the default destination.
Also, without the '-I' option it will recover from tape without interruption, so it'll be the exact copy of your system.

Here you also find more about ignite:
