You can add storage to an existing clustered service or application. However, if the storage has not already been added to the failover cluster itself, you must first add the storage to the cluster before you can add the storage to a clustered service or application within the cluster. For information about adding storage to a cluster, see Add Storage to a Failover Cluster.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at https://go.microsoft.com/fwlink/?LinkId=83477.

To add storage for a clustered service or application

  1. In the Failover Cluster Manager snap-in, if the cluster that you want to configure is not displayed, in the console tree, right-click Failover Cluster Manager, click Manage a Cluster, and then select or specify the cluster that you want.

  2. If the console tree is collapsed, expand the tree under the cluster that you want to configure.

  3. Expand Services and Applications, and then click the service or application that you want to add storage to.

  4. Under Actions (on the right), click Add storage.

  5. Select the disk or disks that you want to add.

    If a disk does not appear in the list, it might not have been added to the cluster yet. For more information, see Add Storage to a Failover Cluster.

Additional considerations

  • To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Manager. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.
