To migrate storage using storage mirroring

1. Connect the new array to the SAN.
2. Zone the array controller ports(s) to the server HBA port(s).
3. Create or present the new LUN(s) on the array.
4. Map the new LUN(s) to the server HBA port(s).
5. Stop any processes that are running on this volume or file system.
6. Rescan hardware using rescan-scsi-bus.sh and scsidev commands, or reboot (optional).
7. Confirm that the operating system has access to the new target storage (Array-B).
8. Bring new disks under Veritas Volume Manager (VxVM) control.
9. Start the VxVM mirroring process to synchronize the plexes between the source and target array enclosures.
10. Monitor the mirroring process.
11. 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.

12. Disconnect the old storage array (enclosure).
