Replace any drive. The data on the new drive is recreated from redundant information on the
2.
remaining drives.
CAUTION: Do not replace any other drive until data rebuild on this drive is complete.
When data on the new drive has been rebuilt (the Activity LED turns off), repeat the previous step for
3.
the other drives in the array, one at a time.
When you have replaced all drives, you can use the extra capacity to either create new logical drives or
extend existing logical drives. For more information about these procedures, refer to the HP Array
Configuration Utility User Guide.
Moving drives and arrays
You can move drives to other ID positions on the same array controller. You can also move a complete
array from one controller to another, even if the controllers are on different servers.
Before you move drives, the following conditions must be met:
If moving the drives to a different server, the new server must have enough empty bays to
accommodate all the drives simultaneously.
The move will not result in more than 14 physical drives per controller channel.
No controller will be configured with more than 32 logical volumes.
The array has no failed or missing drives.
The array is in its original configuration.
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:
It was originally created on a SMART-2/P, SMART-2DH, SA-3200, SA-3100ES, SA-4200, SA-
4250ES, or SA-530x controller.
It is moved to a controller that does not have a battery-backed cache.
It has less than 4 MB of unused capacity.
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:
Back up all data before removing any drives or changing configuration. This step is required if you
1.
are moving data-containing drives from a controller that does not have a battery-backed cache.
Power down the system.
2.
If you are moving an array from a controller that contains a RAID ADG logical volume to a controller
3.
that does not support RAID ADG:
Remove or disconnect the drives that contain the RAID ADG logical volume.
a.
Reboot the server.
b.
Replacing, moving, or adding hard drives 27
