Logical-drive migration is a powerful and flexible feature of ServeRAID controllers. You can use logical-drive migration to:
Using the ServeRAID Manager, you can migrate a logical drive while the server is running with only minor performance degradation for users during the process.
Note: To perform
logical-drive migration, the following must be true:
If a physical drive fails during a logical-drive 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-drive migrations also can recover from a power failure. If power is lost to the server during a logical-drive migration, the migration will restart as soon as power is restored, and complete without data corruption.
Note: (Cluster and
failover configurations only) A logical drive will not failover while undergoing
logical-drive migration.
