Some VCS plexes disabled after power outage

Hi all,

I'm running the Veritas Storage Foundation Standard HA 5.0MP3 under Suse Linux Enterprise Server 11 on two Oracle X6270 servers.

There was a power outage, causing an immediate brutal shutdown of both servers. After power was restored, the server on which the Oracle service group was active ("db1-hasc") could not boot at all (mainboard failure). The other server ("db2-hasc") booted, but reported during boot that cluster cannot start, and that manual reseeding might be needed to start it, so I started the cluster from the working server db2-hasc using command gabconfig -x (found it after some googling).

In the meantime, the failed server db1-hasc was fixed and cluster is now working (all service groups online, but on the db2-hasc, the one which started successfully after power outage). No attempt has been made yet to try to switchover any of the service groups (except network service groups which are online) to the db1-hasc server.

However, I have noticed some problems with several volumes in disk group "oracledg":

db2-hasc# vxprint -g oracledg

Does anyone have some ideas on how to recover the disabled plexes/subdisks?  Or which other commands to run to ascertain the current state of the cluster, in order to have a clear(er) picture what is wrong and which steps to take to remedy the problem?

If so, I would appreciate if you can share any tips/suggestions.

The physical disks seem fine (no errors reported in ILOM diagnostics).

 

Thanks,
