108
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.
1. 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
2. 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
3. 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.
4. 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
5. 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
6. 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.
The following shows an example of executing the command:
host2# /usr/cluster/bin/scconf -c -q
node=host1,maintstate
7. Confirm that the cluster node is in the maintenance mode.
Make sure that the node that is in the maintenance node has the following
status:
