VIO Restore - user Volume Groups problem

[tarro99]

Guys,

has anybody done a mksysb restore of a VIO server?

Tried mine this morning via NIM (and then via DVD-RAM) using a mksysb I had created from the VIO using 'backupios' (onto an NFS mount from the NIM). The restore completed fine (in both cases), and the VIO rootvg appears to work as normal.

However, I have got a problem with the additional User Volume Groups (the ones that I present to client LPARs as Virtual Target Devices). Basically, they cannot be accessed.

'lsvg testvg1' returns "VG must be activated; use activatevg"

'activatevg testvg1' returns "varyonvg: The VG cannot be varied on because there are no good copies of the descriptor area".

However, the PVs containing the VGDAs are still available.

Any ideas? This is something that I need to resolve for our VIO DR process.

All help is very much appreciated.

Cheers,

Chris

Do you get something like

PV Status: hdisk* 000000000 PVNOTFND with the error message?

No, I just get the messages above for when I try to do anything with the additional VGs. The VIO rootvg itself is fine.

Is another (VIO) server accessing the same disks for these volume groups perhaps?
Can you read the disks at all? Try "bootinfo -s hdiskXX" - this just tries to get the size of the disk.
If they are SAN disks, perhaps there are some leftover SCSI reservations on the LUNs in the SAN server.

To answer your first question, I've done both MKSYSB restores via NIM and backios restores from tape.

I'm not sure about the rest of the question, I don't typically use logical volumes for clients. I only do this for sandboxing. I usually present hdisks to clients (thus not data vg's). Wish i could help more.

when you make a NIM mksysb restore with the mksysb image contained in the tarball of the backupios , the mksysb contains all the virtual definitions for the LPAR clients and the ODM definitions for the non rootvg vg's
