Re: failing & corrupt hdisks & mirror... restore VG's from tape?

Wow, thanks for your in-depth response, man, it was very helpful. i'll
tell you what happened:
i removed the definitions of the failing hdisks (1 & 4) with rmdev
commands,
brought the system down, physically removed the disks,
installed the new disks in same slots as old disks,
brought the system up & ran cfgmgr (this was wierd, as it labeled the
disks hdisk6 & hdisk7, even though i had remevoed their def's from the
odm),
exported the vg01 volume group that was on the failed disks,
recreated vg01 on the new hdisks (same pv size, same pp sizes),
tried to restore vg01 from the tape backup that we had (tape backup
included the whole system, which had 2 uservg's; vg01 & vg02).. .tried
using restvg for this, and various smitty restvg, smitty lvm methods
of restoring this VG (vg01) from the tape... but all i would get was
an error:
0512-025 restvg: The image data file does not exist. Restore of
Volume Group cancelled.

anybody have any ideas?

Thanks,
-P
