Removing a Node from a Cluster¶
efm disallow-node command removes the IP address of a node from the
Failover Manager Allowed Node host list. Assume the identity of
the OS superuser on any existing node (that is currently part of the
running cluster), and invoke the
efm disallow-node command, specifying
the cluster name and the IP address of the node:
efm disallow-node <cluster_name> <ip_address>
efm disallow-node command will not stop a running agent; the service
will continue to run on the node until you stop the agent.
If the agent or cluster is subsequently stopped, the node will not be allowed to
rejoin the cluster, and will be removed from the failover priority list (and
will be ineligible for promotion).
After invoking the
efm disallow-node command, you must use the efm
allow-node command to add the node to the cluster again .
