(A1000 Only) If the LUN that you are resetting is a quorum device, relocate that quorum device to
another suitable storage array.
For procedures about how to add and remove quorum devices, see your Oracle Solaris Cluster
system administration documentation. For a list of Oracle Solaris Cluster documentation, see
“Related Documentation” on page 6.
If a volume manager does not manage the LUNs on the controller module that you are resetting,
proceed to
Step 6.
If a volume manager manages the LUNs on the controller module that you are resetting, 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.
# vxdisk offline cNtXdY
# vxdisk rm cNtXdY
On one node, reset the LUN conguration.
For the procedure about how to reset the LUN conguration, see the Sun StorEdge RAID
Manager User’s Guide.
(StorEdge A3500 Only) Set the controller module back to active/active mode.
For more information about controller modes, see the Sun StorEdge RAID Manager Installation
and Support Guide and the Sun StorEdge RAID Manager User’s Guide.
Use the format command to label the new LUN 0.
Remove the paths to the old LUNs you reset.
# rm /dev/rdsk/cNtXdY*
# rm /dev/dsk/cNtXdY*
# rm /dev/osa/dev/dsk/cNtXdY*
# rm /dev/osa/dev/rdsk/cNtXdY*
(StorEdge A3500 Only) Determine the alternate paths to the old LUNs you reset. Use the lad
command.
The RAID Manager software creates two paths to the LUN in the /dev/osa/dev/rdsk
directory. Substitute the cNtXdY number from the other controller module in the storage array
to determine the alternate path.
Example:
# lad
c0t5d0 1T93600714 LUNS: 0 1
c1t4d0 1T93500595 LUNS: 2
