Hello friends,
By using the command as suggested by Robert, "hwmgr -show scsi -full",
I was able to come up with what I need to show compaq.
as in:
# hwmgr -show scsi -full | egrep 'stale|valid'
0 0 0 valid
0 1 0 valid
0 3 0 valid
0 2 0 valid
0 4 0 valid
1 0 0 stale
2 0 0 stale
1 0 0 stale
2 0 0 valid
1 0 1 stale
2 0 1 valid
1 0 2 stale
2 0 2 valid
1 0 3 stale
2 0 3 valid
0 6 0 stale
1 6 0 valid
3 0 0 valid
1 4 0 valid
Thanks to all who responded.

Hello,
This would seem to me to indicate that one of the channels/KZPBA/HSG80 ports
is no longer working. The OS has maked this path as being stale/bad and is
now using another channel to the disks, which is what it should do. However
the path probably failed whilst Oracle was waiting for some info causing it
to lock up. Using the hwmgr command show as "hwmgr -show scsi -full" you
should be able to get a list of paths to the disks and one of them will be
marked stale. So get a hardware engineer in to investigate. Could also be
that somebody unplugged the wrong cable :)
