Try these,
vxprint -htrpq
Look for disabled volumes.. How many disks (sd) you have per plex, check if disk is mirrored or concated
vxdisk list -ao alldgs
Check all disks are online
I'd assume if you're using VxVM, you'll be using vxdmp...
vxdmpadm listenclosure all
vxdmpadm listctlr all
If you're using power path...
powermt display dev=all
Make sure all your paths are good..
If you identify the failing disk,
vxdisk list <c?t?d?>
Should give you the list of paths for that disk, you can then check with inq, (EMC inquiry) and get the LUN number and then check with the "it's not my problem" people, aka storage team
Hope this helps
Cheers

Aaand veritas cluster...
Check cluster status.
hastatus -sum
Other commands
hagrp, hares, all start with ha...
Or if configured use the java interface, might be easier if you're not familiar with the cluster configuration...
