12.16 Adding a Volume to a Clustered Pool

When you use NSSMU, the Storage plug-in for iManager, or the NLVM command line interface to add an NSS volume to a clustered pool, a mount command is automatically added to the load script for the pool cluster resource. Offline and online the primary pool cluster resource to apply the modified load script.

If you add a volume to the primary pool for a clustered DST shadow volume, the mount command is added twice in the primary pool’s cluster load script, once after the primary pool’s activation command and once after the secondary pool’s activation command. You must manually delete the instance that occurs after the secondary pool’s activation, then offline and online the primary pool cluster resource to apply the modified load script.

  1. In iManager under Roles and Tasks, select Storage > Volumes.

  2. Browse to select the Cluster object of the cluster where the pool is currently online.

    You can also select the server where the pool cluster resource is currently mounted.

  3. Click New to open the New Volume wizard, then create the new volume on the shared pool.

    See Creating Unencrypted NSS Volumes in the OES 11 SP2: NSS File System Administration Guide for Linux.

  4. In Roles and Tasks, select Clusters > My Clusters, then select the cluster you want to manage.

    If the cluster you want to manage is not in the list, you can add it. Click Add, browse to locate and select the Cluster object of the cluster, then click OK.

  5. If you added a volume to the primary pool for a DST shadow volume, modify the load script to remove the instance of the mount command that immediately follows the pool activation line for the secondary pool.

    1. Select Cluster Options.

    2. Click the name link of the pool cluster resource to open its Properties page, then click the Scripts tab.

    3. In the load script, delete the mount command for the new volume that follows the pool activation command for the secondary pool.

    4. Click OK to save your changes.

    5. Click Cluster Manager to return to the Cluster Manager page.

  6. On the Cluster Manager page in the Cluster Resource list, select the check box next to the pool cluster resource, then click Offline to take the resource offline.

    Wait for the resource to report itself as Offline before you continue.

  7. In the Cluster Resource list, select the check box next to the pool cluster resource, then click Online to bring the resource online.

    This applies the modified load script, which mounts the newly created volume.
