Removing a Cluster
Clusters that are not in use can be permanently removed. Deleting unused clusters saves system resources, as existing servers are checked(or pinged) at fixed intervals.

Warning

It is recommended that the default cluster should not be removed.

To remove a cluster:

  1. Click the Cluster tab.
  2. If the required cluster is not visible, perform a search (see Section 2.2, “Search”).
  3. Select the cluster to be removed. Ensure that there are no running servers and volumes.
  4. Click the Remove button.
    A message prompts you to confirm removal. The dialog box lists all the clusters that are selected for removal.
  5. Click OK.
    The cluster is deleted and disappears from the Clusters tab.

Note

The servers can still be used, and allocated to a different cluster.
