Removing a Node From a Cluster
This section provides instructions on how to remove a node on a global cluster or a zone
cluster. You can also remove a specific zone cluster from a global cluster. The following table
lists the tasks to perform to remove a node from an existing cluster. Perform the tasks in the order
shown.

Move all resource groups and device groups off the node to be removed. If you have
a zone cluster, log into the zone cluster and evacuate the zone cluster node that is on the physical
node getting uninstalled. Then remove the node from the zone cluster before you bring the physical
node down.
If the affected physical node has already failed, simply remove the node from the
cluster.

clnode evacuate node
|
Verify that the node can be removed by checking the allowed hosts.
If the node is not listed by the claccess show command, it cannot be
removed. Give the node access to the cluster configuration.
|
claccess show
claccess allow –h
node-to-remove
|
Remove the node from all device groups.
|
|
Remove all quorum devices connected to the node being removed.
This step is optional if you are removing a node from a two-node
cluster.
Note that although you must remove the quorum device before you remove the storage device in
the next step, you can add the quorum device back immediately afterward.
|
|
Put the node being removed into noncluster mode.
|
|
Remove a node from the cluster software configuration.

(Optional) Uninstall Oracle Solaris Cluster software from a cluster node.
