4.1.2 How to Remove a Quorum Device
When a quorum disk is removed, it no longer participates in the voting to establish quorum. Note that all two-node clusters require that at least one quorum device be configured. If this is the last quorum device on a cluster, scconf(1M) will fail to remove the device from the configuration.
Note -
If the device you intend to remove is the last quorum device in the cluster, see the procedure "4.1.3 How to Remove the Last Quorum Device From a Cluster".
-
Become superuser on a node in the cluster.
-
Determine the quorum device to be removed.
# scconf -pv | grep Quorum
-
Execute the scsetup(1M) utility.
# scsetup
The Main Menu appears.
-
Access the Quorum Menu by entering 1 (Quorum) to work with the quorum device.
-
Remove the quorum device by entering 2 (Remove a quorum disk).
Answer the questions displayed during the removal process.
-
Quit scsetup.
-
Verify that the quorum device is removed.
# scstat -q
