8.7 Disabling BCC for a Cluster Resource

After enabling a resource for business continuity, it is possible to disable it. You might want to disable BCC for a cluster resource in any of the following cases:

  • You accidentally enabled the resource for business continuity.

  • You no longer want the cluster resource to be able to fail over between peer clusters.

  • You plan to delete the cluster resource.

  • You plan to remove the peer cluster from the business continuity cluster. In this case, you must disable BCC for each cluster resource before you disable BCC for the cluster.

IMPORTANT:If you disable Business Continuity Clustering for a cluster by using either iManager or the cluster disable console command, the cluster resources in that cluster that have been enabled for business continuity are automatically disabled for business continuity. If you re-enable Business Continuity Clustering for the cluster, you must again re-enable each of its cluster resources that you want to be enabled for business continuity.

This can be a time-consuming process if you have many cluster resources that are enabled for business continuity. For this reason, you should use caution when disabling Business Continuity Clustering for an entire cluster.

Before you disable BCC for a BCC-enabled resource, remove the secondary peer clusters from the resource’s assigned list, then disable BCC only from the primary cluster, either by using iManager or command line. Do not attempt to disable BCC on the same resource from multiple peer clusters.

To disable BCC for a cluster resource:

  1. Log in to iManager as the BCC Administrator user.

  2. In Roles and Tasks, click Clusters > My Clusters, then click the cluster name.

  3. Click the Cluster Options tab.

  4. Select the check box next to the desired cluster resource from the list of Cluster objects.

  5. Click the Details link.

  6. On the Preferred Nodes tab, remove the secondary peer clusters from the Assigned list, then disable BCC for the resource on the primary peer cluster.

    1. Click the Preferred Nodes tab.

    2. From the Assigned Nodes list, select the nodes that reside in the secondary peer clusters, then click the arrow button to move the selected servers to the Unassigned Nodes list.

      The primary peer cluster and the node where the resource is running cannot be moved from the Assigned list to the Unassigned list.

    3. Click Apply to save the node assignment changes.

  7. On the Details page, click the Business Continuity tab, deselect the Enable Business Continuity Features check box, then click Apply.

  8. Wait for Identity Manager to synchronize the changes.

    This could take from 30 seconds to one minute, depending on your configuration.

  9. Delete the Cluster Resource object on the clusters where you no longer want the resource to run.

    In iManager, use the Clusters plug-in to delete the cluster resource.

    1. In Roles and Tasks, click Clusters > My Clusters, then click the cluster name.

    2. If the cluster resource is online, take it offline:

      On the Cluster Manager page, select the check box next to the cluster resource, then click Offline.

      Refresh the Cluster Manager page to verify that the resource has a status of Offline before you continue.

    3. Select the Cluster Options tab.

    4. Select the check box next to the resource, then click Delete.

      This deletes the Cluster Resource object. It does not delete the storage or service represented by the object.

      For a pool cluster resource, this also deletes the related NCP virtual server object, Pool object, and Volume object.

    NOTE:Repeat Step 9 on all the clusters where you no longer want the resource to run.
