Media Migration

Executive summary
During the operation of the Dell™ PowerVault™ DL backup to
Disk Appliance Powered by Symantec Backup Exec™, it may
become necessary to migrate or copy backup data from one
appliance to another. Depending on the appliance configuration,
this data may reside on disk, tape, or both. This guide provides
instructions for migrating the data from one appliance to
another for the following items:
Disk Group(s)•
Tape Media•
Tape Library/Libraries•
Data Set(s)•
Disk Group(s) not associated with a PowerVault DL Appliance•
Migrating an entire disk group
An entire Disk Group (the physical drives making up the virtual
disks on the PowerVault DL Appliance) must be migrated
together from one PowerVault DL 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:
Determine the Disk Group for migration.1.
Note: Although Disk Groups in a standard configuration state
(as defined in the Dell PowerVault™ DL 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 dierent or have changed. Using the
following procedure ensures the correct drives are migrated
in all cases.
From Symantec’s Backup Exec Management Console,a.

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”.

the Disk Group is comprised of by either 1) using the
Blink task (see Figure 3) and then manually viewing
the physical drives (now blinking) associated with the
resource on the MD1000 Storage Enclosure; or 2)
by viewing the details of the virtual disk as shown in
Figure 4.

been imported. Backup Exec will automatically discover
and detect the imported Disk Group (listed as an Array in
the Devices tab), including its virtual disks. The contents
of the migrated Disk Group / array must be inventoried
and cataloged before they are available
for use.
Select the9. Devices tab from within the Backup Exec
management console. Right-click the imported virtual
disk and select Inventory from the pop-up menu. Repeat
this step for each imported virtual disk. Once all virtual
disks have been inventoried, their contents must be
cataloged.

Cataloging the migrated disk group
The virtual disks contained in the migrated Disk Group must
be cataloged in Backup Exec once the virtual disks have been
imported and inventoried on the new PowerVault DL Appliance.
Cataloging the virtual disks allows Backup Exec to read and store
the information contained in the virtual disks which includes:
Media number/label/name (something to identify that•
media from all others)
Date and time of the backup•
Type of backup•
What directories/files were backed up•
From the Backup Exec Management Console, perform the
following steps to catalog the imported virtual disks:
From the1. Devices tab, select the first virtual disk that was
imported. Refer to Figure 1 for an example location.
Select all of the media on the right.2.
Right-click all of the media and select3. Catalog Media
from the pop-up menu. Specify the following (if
necessary) on the Catalog Job Properties dialogue:
Under• Device, specify a password if the media is
password protected
Under• General, specify a job name and priority
Under• Schedule, select Run Now to start the

catalog operation. Backup Exec will catalog the media
and it will be available for use.
Migrating tape media

Media Migration
8
It may be necessary to migrate backup sets stored on tape
media from one PowerVault DL Appliance to another. In order
to migrate tape media from one appliance to another, the tape
media must be exported from the tape library attached to the
original appliance.
Exporting Tape Media
An export job must be created to export tape media so that
the Backup Exec database is updated. The Backup Exec export
media job fully supports robotic libraries with portals. When this
job is run on one or more robotic library slots, the exported
media is placed in the portals. If you select more media than
there are portals, the robotic library will fill as many slots as
possible, and then you are prompted to remove the media from
the portal. This process continues until all of the selected media
has been removed from the robotic library.
Open the1. Symantec Backup Exec
Management Console.
Click2. Devices on the navigation bar.
Select the robotic library containing the tape media.3.
Click4. Slots.
On the5. Results pane, select the slots you want to export
tape media from.
Under6. Media Tasks in the Task pane, select Export
media.
Complete the appropriate options as follows:7.
Job Name•
Job Priority•
Select8. Run Now to have the import media operation run.
Importing Tape Media

Media Migration
9
On the PowerVault DL Appliance that you wish to import the
tape media into, you must create an import media job to insert
media into your robotic library so that the Backup Exec database
is updated. The Backup Exec import media job fully supports
robotic libraries with portals. When this job is run, the slots you
selected are checked for media. If media is found, it is exported
to the portals. After all the media has been exported, you are
prompted to insert new media into the portal so it can be
imported. This process continues until all of the requested media
has been imported into the robotic library.
Before you create an import media job, note the following:
If the media does not have a bar code, when you•
create the import job, you must select the option
Auto-inventory after import is completed.
If your robotic library uses a media magazine, make•
sure no jobs are currently running and that all media
are ejected from the drive and are back in the
magazine slots before swapping the magazine.
You can select any number of slots to import.
You can monitor this job on the Job Monitor.
To import media to a robotic library:
On the navigation bar, click1. Devices.
Select the robotic library.2.
Click3. Slots.
On the4. Results pane, select the slots you want to import
media to.
Under5. Media Tasks in the Task pane, select Import
media.
Complete the appropriate options as follows:6.

automatically create an inventory job to run after the
import job completes, under Settings, click Options, and

then select Auto-inventory after import is completed.
Select8. Run Now to have the import media operation run.
Cataloging migrated tape media
The tape media must be cataloged once the tape media has
been imported and inventoried on the new PowerVault DL
Appliance. Cataloging the tape media allows Backup Exec to
read and store the information contained in the tape media
catalog which includes:

Perform the following steps to move a tape library from one
PowerVault DL Appliance to another PowerVault DL Appliance.
Note: The correct number of Library Expansion Option
licenses must be installed on the new appliance to support
your PowerVault Tape Library.
Power down the PowerVault DL Appliance including the1.

Cataloging Media from a Migrated Tape Library
The tape media must be cataloged once the PowerVault Tape
library has completed the inventory process. Cataloging the tape
media allows Backup Exec to read and store the information

Copying Data Sets
Specific media sets can be copied from one PowerVault DL
Appliance to another. Copying sets involves the duplicate
operation to copy media sets from one appliance to another.
Perform the following steps to copy media sets from one
appliance to another:
On the source appliance, create a backup-to-disk folder1.
where the data will reside on the target appliance.
Selecta. Tools › Wizards › Backup-to-Disk.
Clickb. Next to continue the wizard.

Complete the wizard.
Select the9. Devices tab from Backup Exec. Right-click
the backup-to-disk folder created in the previous step
and select Inventory from the pop-up menu. Once the

must be cataloged.
Cataloging copied data sets
The media in the backup-to-disk folder must be cataloged once
the backup-to-disk folder has been inventoried on the new
PowerVault DL Appliance. Cataloging the backup-to-disk folder
allows Backup Exec to read and store the information contained
in the folders which includes:
