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:
During logical-drive migration, the Adaptec Storage Manager creates one logical
drive for temporary use. (You must have an extra logical device onto which
the data can migrate.) The Adaptec Storage Manager sets this logical device to
the system state. When migration is complete, this logical device is removed.
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.
