Adding Disks to the Storage Pool

Updated: April 21, 2010

Applies To: System Center Data Protection Manager 2010

DPM cannot use space in any pre-existing volumes on disks added to the storage pool. Although a pre-existing volume on a storage pool disk might have free space, DPM can use space only in volumes that it creates. To make the entire disk space available to the storage pool, delete any existing volumes on the disk and then add the disk to the storage pool.

DPM regularly rescans the disks and volumes in the storage pool and updates the storage pool space. If you add a disk that contains a volume to the storage pool and later delete that volume, when DPM rescans the disk, it will add the new unallocated space to the available storage pool.

If the name of a disk is listed as “Unknown” on the Disks tab in the Management task area of DPM Administrator Console, you cannot add the disk to the storage pool until the disk name is corrected. To resolve this issue, perform the following procedure.

To correct a disk name

  1. In Device Manager, expand Disk drives.

  2. Right-click each disk listed as "Disk drive", and select Uninstall.

    noteNote
    All disks without a friendly name are listed as “Disk Drive.” An example of a friendly name is “HITACHI_DK23EB-40”.

  3. On the Action menu, click Scan for hardware changes to reinstall the disk.
