Restoration problem with Recovery tape

[admtech]

Hi All,
I have HP 9000 server with HP UX 11.11 installed. I created tape recovery tape with the following command

# make_tape_recovery -x inc_entire=vg00

This command created the tape successfully but when I tryed to reboot the server with this tape to check whether it is working, it did not work.
I chosen to boot from tape libray PATH while booting.
On the console it says that booting from PATH.......(tape library PATH).
and on the tape library it dispays "reading tape", "passed diagnostic test" and after that it displays "tape Ready".
I waited for 30 minuts but On the console there is no changes and still saying that Booting from Path ....

the size of rootvg (vg00) is about 15GB. Should I leave the system for longer time, Indeed I do not have idea that how much time it takes to boot from this recovery tape of this size(15GB)
Please suggest what should I do ? This server is very critical and we do not have disaster recovery plan yet. it is very urgent.

Thanks & Regards,
Ram

Ram,
Did you break out of the regular boot sequence? Then type sea, to get a look at your bootable devices. You probably will type boot P0. That way it will boot from the tape. I say no to interact with ISL when it askes.

Hi All,

Please respond to my problem and also Please let me know the best way to create the complete root volume image on tape so that server can be bring back in original state in case of server crash.

Thanks & Regards,

Consider this: the tape does not understand the boot request from the server, because it is not supported as a hp-ux boot device.

[Torsten.]

But you can try to boot the server from an install media (CD) and read only the archive from the tape (2-step-recovery), available in the advanced option menu.

Hi Ram

Could you try looking into the contents of the tape if there's a successful backup?

mt -f /dev/rmt/0mn status
mt -f /dev/rmt/0mn rew
mt -f /dev/rmt/0mn fsf 1
tar -tvf /dev/rmt/0mn

replace /dev/rmt/0mn with the device file your using.

Could you post the contents of /var/opt/ignite/recovery/latest/recovery.log?
