Deleting a Remote Cluster

The Web Console enables you to delete a remote cluster. This operation involves the following tasks:

  Taking the wac resource in the ClusterService group offline in the cluster that will be removed from the global environment. For example, to delete cluster C2 from a global environment containing C1 and C2, log on to C2 and take the wac resource offline.

  Removing the name of the specified cluster (C2) from the cluster lists of the other global groups; the Web Console updates the cluster lists for heartbeats. Log on to the local cluster (C1) to complete this task using the Global Groups Wizard.

  Removing the cluster (C2) from the local cluster (C1) using the Cluster Summary page on the local cluster (C1).

  Note    You cannot delete a remote cluster if the cluster is part of a cluster list for global service groups or global heartbeats, or if the cluster is in the RUNNING, BUILD, INQUIRY, EXITING, or TRANSITIONING states.
