Sun Cluster software supports the monitoring of quorum devices. Periodically, each node in the cluster tests the ability of the local node to work correctly with each configured quorum device that has a configured path to the local node and is not in maintenance mode. This test consists of an attempt to read the quorum keys on the quorum device.
When the Sun Cluster system discovers that a formerly healthy quorum device has failed, the system automatically marks the quorum device as unhealthy. When the Sun Cluster system discovers that a formerly unhealthy quorum device is now healthy, the system marks the quorum device as healthy and places the appropriate quorum information on the quorum device.
The Sun Cluster system generates reports when the health status of a quorum device changes. When nodes reconfigure, an unhealthy quorum device cannot contribute votes to membership. Consequently, the cluster might not continue to operate.
