Sun Cluster System Administration Guide for Solaris OS

ProcedureHow to Bring a Quorum Device Out of Maintenance State

Run this procedure each time a quorum device is in maintenance state and you want to bring the quorum device out of maintenance state and reset the quorum vote count to the default.

Caution – Caution –

If you do not specify either the globaldev or node options, the quorum count is reset for the entire cluster.

When you configure a quorum device, Sun Cluster software assigns the quorum device a vote count of N-1 where N is the number of connected votes to the quorum device. For example, a quorum device that is connected to two nodes with nonzero vote counts has a quorum count of one (two minus one).

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 of the cluster.

  2. Reset the quorum count.

    # clquorum enable device

    Specifies the DID name of the quorum device to reset, for example, d4.

  3. If you are resetting the quorum count because a node was in maintenance state, reboot the node.

  4. Verify the quorum vote count.

    # clquorum show +

Example 6–9 Resetting the Quorum Vote Count (Quorum Device)

The following example resets the quorum count for a quorum device back to the default and verifies the result.

# clquorum enable d20
# clquorum show +
