10.4. The quorum unblock Command

In a situation in which you know that the cluster is inquorate but you want the cluster to proceed with resource management, you can use the following command to prevent the cluster from waiting for all nodes when establishing quorum.

Note

This command should be used with extreme caution. Before issuing this command, it is imperative that you ensure that nodes that are not currently in the cluster are switched off and have no access to shared resources.
