Dell MD3220, MD3200 Disk Group Migration, Using Unconfigured Capacity, Export Disk Group, 133

Using Unconfigured Capacity

You can increase the capacity of a standard virtual disk or a snapshot repository virtual disk using the unconfigured capacity when no free capacity exists on a disk group. An increase is achieved by adding unconfigured capacity, in the form of unassigned physical disks to the disk group of the standard virtual disk or the snapshot repository virtual disk. See "Disk Group Expansion" on page 131.

For more information, see the PowerVault Modular Disk Storage Manager online help topics.

Disk Group Migration

Disk group migration allows to you export a disk group so that you can import the disk group to a different storage array. You can also export a disk group so that you can store the data offline.

NOTE: During the export process (before the disk group is imported) you lose access to the data on the exported disk group.

NOTE: You must export a disk group before you move the disk group or import the disk group.

Export Disk Group

The export disk group operation prepares the physical disks in the disk group for removal. You can remove the physical disks for offline storage, or you can import the disk group to a different storage array. After you complete the export disk group operation, all of the physical disks are offline. Any associated virtual disks or free capacity nodes are no longer shown in MDSM.

Non-Exportable Components

You must remove or clear any non-exportable settings before you can complete the export disk group procedure. Remove or clear the following settings:

•Persistent reservations

•Host-to-virtual disk mappings

•Virtual disk copy pairs

•Snapshot virtual disks and snapshot repository virtual disks

Configuration: Disk Groups and Virtual Disks
