This topic describes how to add an existing physical disk resource to a clustered mailbox server in a single copy cluster. If the physical disk is created correctly when the cluster is formed, the physical disk resources are created automatically and placed in their own group. In this case, the physical disk resources can be moved safely to the clustered mailbox server's group and integrated into its resource model.

After the move is completed, the empty resource groups can be deleted.

Before You Begin

You must be logged on as a local administrator on a node of the cluster.


To add a physical disk resource to a clustered mailbox server in a Windows Server cluster

  1. Open Cluster Administrator.

  2. Double-click the cluster name and select the Resources folder.

  3. Select the existing drive to be moved, verify that it is online, and that it is not in use by the cluster group or another clustered mailbox server.

  4. Make sure the physical disk resource is in the right group. If not, right-click the existing drive and select Change Group, and then select the clustered mailbox server. A confirmation dialog box will appear. Verify that the correct resource is being moved, and then click Yes. A second dialog box will appear and prompt you for additional resources that must be moved because of dependencies. If the list of resources is correct, click Yes.

  5. Right-click the Physical Disk resource and then click Properties.

  6. In Possible Owners, under Possible owners, verify that all nodes are listed, and then click Next.

  7. In Dependencies, under Resource dependencies, verify that no resources are listed if the drive is presented as a drive letter, and then click Next. If the drive is presented as a mount point, make the physical disk hosting the mount directory be a dependency of this resource. This is done by selecting the correct physical disk, and then clicking Add.

  8. In Disk Parameters, in the Disk list, select the disk that you want. If the disk does not appear in this list, either another group already has a resource for the disk, or the disk was not installed successfully.

    If the drive is presented as a mount point, the disk number and label appears instead of a drive letter.
  9. Right-click the disk and select Properties. Select the Advanced tab. Ensure that Affect the group is not selected, and then click OK.

  10. Right-click any database resources that require this disk to be online to successfully mount and point to properties. For each database resource, make the newly created disk a dependency by selecting the Properties tab, and then click the Modify button. Select the appropriate disk, click the -> button, click OK, and then click OK again to confirm the properties dialog box.
