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.
In most cases, a moved array (and the logical drives that it contains) can still
undergo array capacity expansion, logical drive capacity extension, or
migration of RAID level or stripe size. An exception occurs when the array
meets all of these conditions:
If a controller contains a RAID ADG logical volume, none of the arrays on
the controller can be moved directly to a controller that does not support
RAID ADG. The arrays can be moved indirectly, as described by the
instructions in this section.
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 system.
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
b. Reboot the server.
