8.8 Deleting or Unsharing a BCC-Enabled Shared NSS Pool Resource

You might need to unshare a pool resource if you decide not to cluster the pool. You might decide to delete an NSS pool if the data stored on it is no longer needed.

Consider the following guidelines when planning to delete or unshare a BCC-enabled pool resource:

  • All resource configuration must happen from the master node. On the Cluster Options page for iManager, connect to the Cluster object, not to Cluster Node objects. On the Storage > Pools page for iManager, connect to the master node. Run NSSMU only on the master node.

  • You must disable BCC for a shared NSS pool before you delete it or unshare it. This allows the pool to be removed from the list of resources kept by the peer clusters.

  • You must offline the cluster resource before attempting to delete either the cluster resource or the clustered pool. For example, if you want to unshare a pool, offline the cluster resource for the pool before you mark the pool or the device as Not Shareable for Clustering; then you can delete the eDirectory object for the cluster resource.

    WARNING:If you attempt to delete a cluster resource without first offlining it, deletion errors occur, and the data associated with the clustered pool is not recoverable.

To delete or unshare a BCC-enabled shared NSS pool resource:

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

  2. Click the Cluster Options tab.

  3. If the resource is on a non-master node in the cluster, migrate it to the master node. Select the resource, click Migrate, then specify the master node.

  4. Select the shared NSS pool resource, click Properties, then select Business Continuity.

  5. Disable BCC for the pool cluster resource, then click Apply.

    For information, see Section 8.7, Disabling BCC for a Cluster Resource.

    Wait for Identity Manager to synchronize the change to all peer clusters before continuing. You can check the other peer clusters to ensure that the cluster resource you BCC-disabled no longer appears in their list of resources.

  6. Go to the Cluster Manager page, select the check box next to the NSS pool cluster resource, then click Offline.

  7. Do one of the following:

    Task

    Procedure

    Keep the shared NSS pool to use it only in the current cluster.

    1. Click the Cluster Options tab.

    2. Select NSS pool resource to view Properties, then select Scripts.

    3. Modify the load script by removing any commands related to the BCC, then click Apply.

    4. Modify the unload script by removing any commands related to the BCC, then click Apply.

    5. Modify the monitor script by removing any commands related to the BCC, then click Apply.

    6. Click OK.

    7. Go to the Cluster Manager page, select the check box next to the NSS pool cluster resource, then click Online.

    Keep the NSS pool, but unshare it to use it as a non-clustered pool.

    1. In iManager, select Storage > Pools, then select the master node of the cluster.

    2. Select the pool to view its Pool Details. (It should be deactive since the resource was offline when you modified the script.)

    3. Mark the pool as Not Shareable for Clustering, then click Apply.

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

    5. Click the Cluster Options tab.

    6. Select the check box next the Cluster Resource object you want to delete, then click Delete.

    Unshare the pool, then delete it.

    1. In iManager, select Storage > Pools, then select the master node of the cluster.

    2. Select the pool to view its Pool Details. (It should be deactive since the resource was offline when you modified the script.)

    3. Mark the pool as Not Shareable for Clustering, then click Apply.

    4. Select Clusters > My Clusters, select the cluster, then select the Cluster Options tab.

    5. Select the check box next the Cluster Resource object you want to delete, then click Delete.

    6. In iManager, select Storage > Pools, then select the node of the cluster.

    7. Select the pool to view the Pool Details.

    8. Click Delete, then confirm the deletion.
