It would be easier if you know the boot disk path for recovery process,if you have an earlier o/p..

If your boot volume is corrupted,you cant bring the system to ISL.

Boot the system from Recovery disk and rebuild the bootlif.

Physical Volumes belonging in Root Volume Group:
/dev/dsk/c2t0d0 (0/1/1/0.0.0) -- Boot Disk
/dev/dsk/c3t2d0 (0/1/1/1.2.0)
/dev/dsk/c2t1d0 (0/1/1/0.1.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c2t0d0
/dev/dsk/c2t1d0

Alone root disk should be restored with recovery media, and mirrored disk can be booted with the alternate path.

Ypu can also invole an fsck on the volume..

If the filesystem is corrupted, it will be the same on all the mirrors too, because it's a mirror ...

If you cannot boot to repair, your option is to restore from ignite.

Ignite is a package with several programs designed to save and then restore the root volume. Before you can restore anything, you have to backup the data. With a single HP-UX system, you have no choice but to backup the data onto tape using make_tape_recovery. But this also assumes that you have the Ignite package installed:

swlist -l product Ignite-UX

If Ignite is not installed, download a copy immediately from: http://www.hp.com/go/ignite-ux. Also get the Ignite Admin Manual too. If you have several HP-UX servers, you can setup an Ignite network server and backup the root volume to this server (and restore the volume if needed).
