HP StorageWorks MSA500 G2 User Manual page 65

•
The controller is not reading from or writing to any of the spare drives in the
array.
•
The controller is not running capacity expansion, capacity extension, or
RAID or stripe size migration.
•
The controller is using the latest firmware version (recommended).
If you want to move an array to another controller, you must also consider the
following additional limitations:
•
All drives in the array must be moved at the same time.
•
Drive positions of the destination controller must match original drive
positions.
When all the conditions have been met:
1. Back up all data before removing any drives or changing configuration. This
step is required if you are moving data-containing drives from a controller
that does not have a battery-backed cache.
2. Power down the storage system (on page 28).
3. If you are moving an array from a controller that contains a RAID ADG
logical volume to a controller that does not support RAID ADG:
a. Remove or disconnect the drives that contain the RAID ADG logical
volume.
b. Reboot the storage system.
c. Open ACU and navigate to the controller that contained the RAID ADG
volume.
ACU displays the missing RAID ADG volume using a different icon to
indicate that the volume is unavailable.
d. Delete the RAID ADG volume.
e. Accept the configuration change, and then close ACU.
f. Power down the storage system (on page 28).
4. Move the drives.
5. Power up the storage system (on page 27).
