Dell PowerVault DL2000 - Manual (Page 3)

Media Migration
3 December 2008
An entire Disk Group (the physical drives making up the virtual disks on the PowerVault DL
Backup to Disk Appliance) must be migrated together from one PowerVault DL Backup to Disk
Appliance to another. Migrating single drives or partial drives in a Disk Group will result in data
loss for the entire Disk Group.
Perform the following steps to migrate a Disk Group from one appliance to another:
1. Determine the Disk Group for migration.
Note: Although Disk Groups in a standard configuration state (as defined in the Dell
PowerVault™ DL Backup to Disk Appliance Powered by Symantec Backup Exec Quick Start
Guide) are typically contained in Slots 1-7 or Slots 8-14 on each PowerVault MD1000
Storage Enclosure, there are cases where the slot locations may be different or have
changed. Using the following procedure ensures the correct drives are migrated in all cases.
a. From Symantec’s Backup Exec Management Console, select the Devices tab
and then determine the “Hardware name” of the resource of the Storage Array to
be migrated.
In the example found in Figure 1, “VIRTDISK 8” in “ARRAY 1” is going to be
migrated, and its associated hardware name is “VDS_CREATED_001”.
