Figure 4-13 Example of executing the format command
In the above execution example, when you specify an LU, the message
Disk not labeled. Label it now? will be output if a disk label has not
been specified. In this case, enter y and specify a disk label.

If setup is being performed for Quorum devices and disk device groups in
the LU to be managed by HDLM, release the LU settings.
When you unregister the SDS or SVM diskset, the diskset data will be
deleted so first back up any necessary data. For details on how to release
settings for Quorum devices and VxVM disk groups, see Remove Sun
Cluster Settings on page 3-180 of Preparations for HDLM Removal on
page 3-179 .

Settings on page 3-183 or Remove SVM Settings on page 3-184 of

Make sure that registration is performed for the key used in disk
reservation for the LU to be managed by HDLM. Execute the following
command on any node:
# /usr/cluster/lib/sc/scsi -c inkeys -d the-name-of-the-logical-
device-file-of-slice-2-of-the-LU-to-be-managed-by-HDLM
The following shows an example of executing the command:
# /usr/cluster/lib/sc/scsi -c inkeys -d /dev/rdsk/

If the key is displayed, perform the steps beginning with step 5. Even
when you release the setup for Quorum devices and disk device groups,
since the key used for disk reservation will remain registered, you will
need to restart the node in non-cluster mode and unregister the key.
If the key is not displayed, perform the steps beginning with step 9.

Simultaneously stop all nodes in the cluster.
