If the settings of a Quorum device or disk device group are specified for
the device to be managed by HDLM, remove those settings.
For details on how to remove the Quorum device and the VxVM disk
group settings, see Set Up Sun Cluster on page 3-50 in Preparations for a
New Installation of HDLM on page 3-45 .
For details on how to unregister an SDS or SVM diskset, see Remove SDS
Settings on page 3-183 or Remove SVM Settings on page 3-184 in
Preparations for HDLM Removal on page 3-179 . Unregistering a diskset
deletes the data in the diskset. Therefore, back up a diskset before
unregistering it.

.
Make sure that the key to be used for disk reservation has been
registered with the device to be managed by HDLM.
On any one node, execute the following command:
# /usr/cluster/lib/sc/scsi -c inkeys -d slice-2-logical-device-
file-name-for-the-device-to-be-HDLM-managed
The following shows an example of executing the command:
# /usr/cluster/lib/sc/scsi -c inkeys -d /dev/rdsk/c5t0d0s2
Reservation keys(3):
0x40235c5200000002
0x40235c5200000001
0x40235c5200000003
#
In this example, keys are displayed.
If keys are displayed, perform the steps beginning with step 7. Even if the
Quorum device or disk device group settings are removed, you need to
restart the node in non-cluster mode and cancel the key registration
because the keys to be used for disk reservation are left registered.
