Use the clquorum show command to determine the following information:
Total configured votes
Current present votes
Votes required for quorum
See the cluster(1CL) man page.
Both nodes and quorum devices contribute votes to the cluster to form quorum.
A node contributes votes depending on the node's state:
A node has a vote count of one when it boots and becomes a cluster member.
A node has a vote count of zero when the node is being installed.
A node has a vote count of zero when a system administrator places the node into maintenance state.
Quorum devices contribute votes that are based on the number of votes that are connected to the device. 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).
A quorum device contributes votes if one of the following two conditions are true:
At least one of the nodes to which the quorum device is currently attached is a cluster member.
At least one of the hosts to which the quorum device is currently attached is booting, and that host was a member of the last cluster partition to own the quorum device.
You configure quorum devices during the cluster installation, or afterwards, by using the procedures that are described in Chapter 6, Administering Quorum, in Sun Cluster System Administration Guide for Solaris OS.
