Sun Cluster System Administration Guide for Solaris OS

ProcedureHow to Remove a Quorum Device

You can also accomplish this procedure by using the Sun Cluster Manager GUI. See the Sun Cluster Manager online help for more information.

When a quorum device 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, clquorum(1CL) will fail to remove the device from the configuration. If you are removing a node, remove all quorum devices connected to the node.


Note –

If the device you intend to remove is the last quorum device in the cluster, see the procedure How to Remove the Last Quorum Device From a 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.

  1. Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization on any node in the cluster.

  2. Determine the quorum device to be removed.


    # clquorum list -v
    
  3. Execute the clsetup(1CL) utility.


    # clsetup
    

    The Main Menu is displayed.

  4. Type the number that corresponds to the option for Quorum.

  5. Type the number that corresponds to the option to remove a quorum device.

    Answer the questions displayed during the removal process.

  6. Quit clsetup.

  7. Verify that the quorum device is removed.


    # clquorum list -v
    

Example 6–5 Removing a Quorum Device

This example shows how to remove a quorum device from a cluster with two or more quorum devices configured.


Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization on any cluster node.

[Determine the quorum device to be removed:]
# clquorum list -v
[Start the clsetup utility:]
# clsetup
[Select Quorum>Remove a quorum device]
[Answer the questions when prompted.] 
Quit the clsetup Quorum Menu and Main Menu.]
[Verify that the quorum device is removed:]
# clquorum list -v
 
 Quorum         Type
-------         ----
scphyshost-1    node
scphyshost-2    node
scphyshost-3    node

Troubleshooting

If you lose communications between the cluster and the quorum server host while removing a quorum server quorum device, you must clean up stale configuration information about the quorum server host. For instructions on performing this cleanup, see Cleaning Up Stale Quorum Server Cluster Information.
