Understanding logical device migration

Logical device migration is a powerful and flexible feature of controllers in a Adaptec Storage Manager system. You can use logical device migration to:

You can migrate a logical device while the server is running with only minor performance degradation for users during the process. You can start the migration immediately or schedule it for a later date and time.

 HostRAID controllers do not support logical device migration.

Notes: To perform a logical-drive migration, the following must be true:

  1. The logical device that you have selected to migrate must be in the optimal state.

  2. The logical device cannot be configured with RAID level-10 or RAID level-50.

If a physical drive fails during a logical device migration and you are migrating between RAID levels other than RAID level-0, the migration will continue and complete. Then, you must replace and rebuild the failed physical drive.

Logical device migrations also can recover from a power failure. If power is lost to the server during a logical device migration, the migration will restart as soon as power is restored and complete without data corruption.
