Dell PowerVault DL backup

to Disk Appliance

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.

Media Migration

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”.

launch Dell’s OpenManage Server Administrator

(OMSA). Select Virtual Disks from the appropriate

PERC 6/e Adapter as seen in Figure 2 and locate the

hardware name of the resource to be migrated as

determined in step 1.a.

Determine and make note of which physical disksc.

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.

the MD1000 Storage Enclosure connected to the target

PowerVault DL Appliance.

Note: If the goal is to keep the Disk Conﬁguration State as

Standard, the migrated Disk Group must occupy Slots 1-7

or Slots 8-14 in the new MD1000 Storage Enclosure. The

optional hot spare should be installed in Slot 0.

From the target PowerVault DL Appliance Console,6.

launch Dell’s OpenManage Server Administrator (OMSA)

tool. Import the migrated Disk Group(s) using OMSA.

Refer to the Dell OpenManage Server Administrator

(OMSA) User Guide for speciﬁc steps. Note: Use the

OMSA procedure for importing foreign conﬁgurations.

On the target PowerVault DL appliance, reset the Disk7.

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.

Media Migration

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

Inventory Operation

Continue to specify the settings for each media in the4.

catalog operation. Backup Exec will catalog the media

and it will be available for use.

Migrating tape media

Media Migration

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

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.

Job Name•

Backup Exec must inventory the media after it has7.

been placed in the library. In order for Backup Exec to

automatically create an inventory job to run after the

import job completes, under Settings, click Options, and

Media Migration

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:

Tape number/label/name (something to identify that tape•

from all others, which is typically the barcode for tape media)

Date and time of the backup•

Type of backup•

What directories/ﬁles were backed up•

Perform the following steps to catalog the imported tape media:

Click the tape drive/robotic library.1.

Select the slots containing the tape media that was just2.

Right-click the tapes/slots and select3. Catalog.

Migrating a tape library

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.

server and attached tape library.

Perform the necessary steps to disconnect the2.

PowerVault Tape Library from the original appliance

and connect the PowerVault Tape Library to the new

appliance. Refer to your PowerVault Tape Library

documentation for more information on cabling your
