This procedure removes the last quorum device from a cluster. Use this procedure only if you have a two-node cluster and you are removing one of the nodes. If one of the nodes fails, use the -F option to remove the device. Generally, you should first add the replacement quorum device and then remove the failed device. Adding a quorum device involves a node reconfiguration, which touches the failed quorum device and panics the machine. The Force option lets you remove the failed quorum device without panicking the machine.
If the device you intend to remove is not the last quorum device in a two-node cluster, follow the steps in How to Remove a Quorum Device.
All two-node clusters require at least one configured quorum device. If this is the last quorum device on a two-node cluster, the cluster must be placed into install mode before clquorum(1CL) enables you to remove the device from the configuration. This procedure should only be performed if a node is being removed from the cluster.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix B, Sun Cluster Object-Oriented Commands.
Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization on any node in the cluster.
Place the node to be removed in maintenance state.
Remove the quorum device by using the clquorumcommand. If the quorum device failed, use the -F Force option to remove the failed device.
The clsetup(1CL) cluster-administration menu options are not available while the cluster is in install mode.
# clquorum remove -F qd1
Verify that the quorum device has been removed.
# clquorum list -v
This example shows how to remove the last remaining quorum device in a cluster configuration.
