I have a SAN disk that is flagged under Veritas as "failing" - through
VEA and output of vxprint. Although all the volumes and filesystems on
this disk seem to be fine. Is this disk actually failing, or is there
something simple that Veritas needs in order to accept this disk.

root #> vxdisk list
DEVICE TYPE DISK GROUP STATUS
c0t0d0s2 sliced - - error
c0t0d0s6 simple c0t0d0s6 rootdg online
c0t8d0s2 sliced - - error

c0t10d0s2 sliced - - error
c4t0d0s2 sliced THEDG27 THEDG online
c4t0d1s2 sliced THEDG28 THEDG online failing

root #> vxprint -ht

Thanks you kind souls.

"failing" is just a flag on the disk. VxVM sets that when it sees
errors in communicating that aren't so serious that the disk is dropped
from the configuration (as would happen if all r/w stopped).

You can clear the flag, but you should look for errors to see what
caused the flag to be set in the first place.

Since this is a SAN, the "disk" may be a virtual device of some sort.
It could be a disk problem, array problem, switch/fiber issue, HBA,
etc...

Read the flag as "something went wrong here at least once. Please see
if you can determine what and fix it."
