In my experience, if you are running AIX (maybe other OS's) you will not be
able to mount the volume.
I would set the affected volumes to read-only and empty them, any remaining
objects are damaged and not recoverable unless there is a copy on tape.
Discard the bad objects and re-run the backups.
Was this a hardware only problem, or were outside forces required to get two
drives to fail?

Primary Pool Disk - so if I have to run a fix=yes, there is 'NO' copy in a
backup poo,, I would then have to rerun the backups.

Subject: CX700 ATA failure - Audit Storage Pool Volumes
TSM Server 5.2.3.5
AIX Operating System 5.2
We have lost two drives on a single ATA RAID array. EMC CE is on site and
working with the EMC SAC to resolve the problem. We brought TSM Server
down while EMC is working on the issue. I started receiving the
following errors before we stop all processes, backups, migrations marking
the effected diskpool volumes read-only.
05/04/05 09:06:36 ANR1411W Access mode for volume
/tsmpool39/diskpool22a now
set to "read-only" due to write error. (SESSION:
125991)
My question is >
When we bring the server back up. I want to ensure that I am doing the
right thing, or if I am missing anything.
1. I will need to make sure the volumes affected are online and in a
read/write status.
2. Audit diskpools volumes, Inspect only first
3. If there are damaged volumes,rerun audit volume, with Fix=Yes.
4. Suggestions?
