Overview of storage mirroring for migration
The migration example occurs between a Hitachi 9900 array, 350 GB disk/LUN and a NetApps 3050 Fibre-Attached 199GB disk/LUN.
To migrate storage using storage mirroring
- Connect the new array to the SAN.
- Zone the array controller ports(s) to the server HBA port(s).
- Create or present the new LUN(s) on the array.
- Map the new LUN(s) to the server HBA port(s).
- Stop any processes that are running on this volume or file system.
- Rescan hardware using rescan-scsi-bus.sh and scsidev commands, or reboot (optional).
- Confirm that the operating system has access to the new target storage (Array-B).
- Bring new disks under Veritas Volume Manager (VxVM) control.
- Start the VxVM mirroring process to synchronize the plexes between the source and target array enclosures.
- Monitor the mirroring process.
- After mirroring is complete, logically remove disks from VxVM control.
Note: |
The example Linux system happens to be running as a Veritas NetBackup Puredisk server which includes the Storage Foundation software. Puredisk also supports this mode of storage array migration. |
- Disconnect the old storage array (enclosure).
