Release the disk device groups that consist of the sd or ssd devices to be
managed by HDLM.
For details on how to unregister an SDS or SVM diskset, see

diskset deletes the data in the diskset. Therefore, back up a diskset
before unregistering it.
To remove a VxVM disk group from Sun Cluster's disk device group,
perform the following procedures:
a
.
Place the target disk device group offline.
# /usr/cluster/bin/scswitch -F -D disk-device-group-name
b
.
Start the scsetup utility.
# /usr/cluster/bin/scsetup
c
.
Select 5 (Device group and volumes) to display Device Group Menu.
d
.
To unregister a VxVM disk group, select 3 (Unregister a VxVM device
group).
Following the displayed directions, enter the name of the disk group
you want to unregister.
•
If an sd or ssd device to be managed by HDLM has been set as a Quorum
device, perform the following procedures to remove the Quorum device
settings.
a
.
Use the following commands to check the device ID of the Quorum
device:
# /usr/cluster/bin/scconf -pv | grep Quorum
# /usr/cluster/bin/scdidadm -L
b
.
If multiple Quorum devices exist, execute the following command until
the number of Quorum devices becomes one. When the number of
Quorum devices finally becomes one, go to step 3.
# /usr/cluster/bin/scconf -r -q globaldev=Quorum-device's-
device-ID
c
.
Switch to become the superuser in the node that is to be changed to
the maintenance mode in order to release the settings of the last
Quorum device.
d
.
Back up all resource groups and sd or ssd devices from the node that
is to be changed to maintenance mode.
The following shows an example of executing the command:
host1# /usr/cluster/bin/scswitch -S -h host1
e
.
Shut down the node to be changed to the maintenance mode so that
the ok prompt appears.
The following shows an example of executing the command:
host1# shutdown -g0 -y -i0
f
.
At another node in the same cluster, switch to become the superuser,
and then place the node that was stopped in step 5 into the
maintenance mode.
