6.

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.
If no key is displayed, perform the steps beginning with step 11.

7.

Stop all nodes that comprise the cluster. On any one node, execute the following

command:


# /usr/cluster/bin/scshutdown -g0 -y

8.

Start all nodes comprising the cluster in non-cluster mode.
Execute

boot

-x

at the

ok

prompt.

9.

Cancel the key registration for the device to be managed by HDLM.
On any one node, execute the following command:


# /usr/cluster/lib/sc/scsi -c scrub -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 scrub -d /dev/rdsk/c5t0d0s2
