4 To unregister a VxVM disk device group, enter 3 (Unregister a VxVM
.
device group).
As the utility instructs, enter the name of the VxVM disk device group you
want to unregister.
If the HDLM device has been configured as a Quorum device, perform the
following operations to remove the Quorum device settings.
1 Check the device ID of the Quorum device.
.
The following shows an example of executing the command:
# /usr/cluster/bin/scconf -pv | grep Quorum
# /usr/cluster/bin/scdidadm -L
2 Since the device ID may have changed after HDLM uninstallation, on each
.
node check the correspondence of the device with the internal LUNs of
the LUs in the storage system.
The following shows an example of executing the command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
3 When two or more 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 4.
# /usr/cluster/bin/scconf -r -q globaldev=Quorum-device's-device-
ID
4 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.
5 Back up all resource groups and HDLM devices from the node that are to
.
be changed to the maintenance mode.
The following shows an example of executing the command:
host1# /usr/cluster/bin/scswitch -S -h host1
6 Shut down the node that is 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
7 At another node in the same cluster, switch to become the superuser, and
.
then place the node that was stopped in step 6 into the maintenance
mode.
The following shows an example of executing the command:
host2# /usr/cluster/bin/scconf -c -q node=host1,maintstate
