MEDIA MIGRATION DELL POWERVAULT DL 2000 POWERED BY SYMANTEC
Media Migration EXECUTIVE SUMMARY During the operation of the Dell™ PowerVault™ DL2000 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.
Media Migration MIGRATING AN ENTIRE DISK GROUP 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.
Media Migration b. From the DL Backup to Disk Appliance Console, 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. Figure 2: OMSA view of storage resource to be migrated c.
Media Migration Figure 4: Physical disks associated with the resource to be migrated 2. 3. 4. 5. Power down the PowerVault DL Backup to Disk Appliance, including the server and all attached MD1000 Storage Enclosures. Remove the physical disks for the Disk Group to be migrated as determined in Step 1.c. On the target PowerVault DL Backup to Disk appliance, set the Disk Configuration Policy to Manual via the Appliance Management Console.
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 Backup to Disk Appliance.
Media Migration MIGRATING TAPE MEDIA It may be necessary to migrate backup sets stored on tape media from one PowerVault DL Backup to Disk 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.
Media Migration CATALOGING MIGRATED TAPE MEDIA The tape media must be cataloged once the tape media has been imported and inventoried on the new PowerVault DL Backup to Disk Appliance.
Media Migration MIGRATING A TAPE LIBRARY Perform the following steps to move a tape library from one PowerVault DL Backup to Disk Appliance to another PowerVault DL Backup to Disk Appliance. Note: The correct number of Backup Exec Library Expansion Option licenses must be installed on the new appliance to support your PowerVault Tape Library. 1. 2. 3. 4. 5. 6. 7. Power down the PowerVault DL Backup to Disk Appliance including the server and attached tape library.
Media Migration COPYING DATA SETS Copying Data Sets Specific media sets can be copied from one PowerVault DL Backup to Disk 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: 1. 2. 3. 4. 5. 6. 7. 8. 9. December 2008 On the source appliance, create a backup-to-disk folder where the data will reside on the target appliance. a.
Media Migration 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 Backup to Disk Appliance.
Media Migration MIGRATING AN UNASSOCIATED DISK GROUP Disk Group(s) from other systems (e.g., another Dell PowerEdge Server with attached storage enclosures) may be migrated to a PowerVault DL Backup to Disk Appliance. Perform the following steps to migrate a Disk Group from one system to a targeted PowerVault DL Backup to Disk Appliance: 1. 2. 3. 4. 5. Determine the Disk Group for migration. Power down the system that owns the Disk Group, including the server and all attached MD1000 Storage Enclosures.
Media Migration SUMMARY The need to migrate or copy backup data from one Dell PowerVault DL Backup-to-Disk Appliance to another is handled via straightforward processes and procedures. Depending on the appliance configuration, this data may reside on disk, tape, or both. The procedures contained herein provide a direct methodology to accomplish the aforementioned tasks.
