If a volume manager does not manage the LUN that you are deleting, proceed to
If a volume manager manages the LUN that you are deleting, remove the LUN from any diskset
or disk group. For more information, see your Solaris Volume Manager or Veritas Volume
Manager documentation.
LUNs that were managed by Veritas Volume Manager must be removed from Veritas Volume
Manager control before you can delete the LUNs. To remove the LUNs, after you delete the
LUN from any disk group, use the following commands.
#
vxdisk offline c
N
t
X
d
Y
#
vxdisk rm c
N
t
X
d
Y
Delete the LUN.
For the procedure about how to delete a LUN, refer to your storage device's documentation.
Remove the paths to the LUNs you are deleting.
#
rm /dev/rdsk/c
N
t
X
d
Y
*
#
rm /dev/dsk/c
N
t
X
d
Y
*
Complete the removal of the paths by issuing the following RAID Manager commands.
#
rm /dev/osa/dev/dsk/c
N
t
X
d
Y
*
#
rm /dev/osa/dev/rdsk/c
N
t
X
d
Y
*
(StorEdge A3500 Only)
Determine the
alternate
paths to the LUNs 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 are deleting.
#
rm /dev/osa/dev/dsk/c
N
t
X
d
Y
*
#
rm /dev/osa/dev/rdsk/c
N
t
X
d
Y
*
On both nodes, remove all obsolete device IDs.
#
cldevice clear
Move all resource groups and device groups off the node.
#
clnode evacuate
