If a volume manager does not manage any of the LUNs on the controller module you are
removing, proceed to
Step 12 .
If a volume manager manages any LUNs on the controller module that you are removing,
remove the LUN from any diskset or disk group.
For more information, see your Solaris Volume Manager or Veritas Volume Manager
documentation.
You must completely remove LUNs that were managed by Veritas Volume Manager from
Veritas Volume Manager control before you can delete the LUNs.

Delete the LUN.
For the procedure about how to delete a LUN, see your storage device's documentation.
Remove the paths to the LUNs you deleted in Step 7 .

(StorEdge A3500 Only) Use the
lad
command to determine the alternate paths to the LUN you are
deleting.
The RAID Manager software creates two paths to the LUN in the
/dev/osa/dev/rdsk
directory. Substitute the
c
N
t
X
d
Y number from the other controller module in the storage array
to determine the alternate path.
For example:
# lad
c0t5d0 1T93600714 LUNS: 0 1
c1t4d0 1T93500595 LUNS: 2
Therefore, the alternate paths are as follows:
/dev/osa/dev/dsk/c1t4d1*
/dev/osa/dev/rdsk/c1t4d1*
(StorEdge A3500 Only) Remove the alternate paths to the LUNs you deleted in Step 7 .
# rm /dev/osa/dev/dsk/c

# rm /dev/osa/dev/rdsk/c

Disconnect all cables from the storage array and storage system. Remove the hardware from
your cluster.
