HP-UX

Since we do not know your configuration it will be difficult to say more...
As I said remove the faulty disk to avoid confusion - or if you think ( possible ) that it is still good but not bootable, remove the sane and try...
This is a task any HP-UX admin has done a few times in his life, especially with HP-UX 10.20 and 11.00 for it is the only way to change the size of the 3 contiguous logical volumes ( /, /stand, lvol2(swap)). It was also a way to clone boxes...
If this can recomfort you:

Code:

raz01:/home/vbe $ uname -a;model;uptime
HP-UX raz01 B.11.00 U 9000/800 503746527 unlimited-user license
9000/800/L1000-36
 10:57am  up 432 days, 15:55,  3 users,  load average: 0.03, 0.03, 0.03

after I manage to boot up from recovery tape, can I just run the recover -f /dev/rmt/0m -rv (to perform full restoration to the box) rather than Install fresh HPUX OS. As I don't think I can't find the patch. Is this right approach ?

No!
Either you let the tape manage on its own (which means it will do a minimum installation (there is all the boot things to do...) then a minimum of OS is needed to continue...) in which case you boot on the tape and do nothing else till it has finished or you interact in order to customize the settings (e.g. the LVM layout). If you were happy with the settings at the time the tape was made, then let the tape do his job...
What patch were you looking for?

vbe, thanks for prompt reply.
Can I say that after I manage to boot up from tape recovery following is my tasks to perform :
1. install hpux (rather than choose recover shell) question is will it intelligent enuf
2. perform LVM layout (can restore from tape into /etc/lvmtab and /etc/mnttab )
:: in this step I will perform lvmlnboot -v to verify, if error will use the lvreduce to break mirror.
3. Reboot the server to ensure the system able to boot from Unmirror Disk.
4. recover –f /dev/rmt/0m –rv
5. mount -a

Thanks

The tape has an option: -i if used when generating the tape... If it were not the case the tape process as you have seen can be interrupted to go in interactive mode, but this is of no use unless you want to interact with the system to modify e.g LVM layout.
If you boot from the tape and dont interfere, it will go in batch mode and every thing for you... It will take him about 3-4 hours...

That said
Your task will be after to restore every thing after using your backup software because your system (vg00 that is ) will be at the state the ignite tape was produced...
Files that may have changed are /etc/passwd ( and new accounts...), was the machine patched since? Have you created new FS since etc..

Good luck
Before If you can, try to read the /var/opt/syslog/syslog.log or OLDsyslog.log to see if it did complain about bad disk.. if not you may have had a corruption where a disk was not bootable...

Thanks vbe, after boot up using the recovery tape, I choose "Install HP Unix" and select basic installation (don't go for Advance option). Once Submit, the restoration begin and it take about 2 hours to complete. Actually I previously confuse with the "Install HP-UX" which I thought it will install the HP-UX original OS, but it fact, the recovery tape will install and recovery to the state as at the time to perform tape recovery. Thanks again.
