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:
•The server must be powered down.
•If moving the drives to a different server, the new server must have enough empty bays to accommodate all the drives simultaneously.
•The array has no failed or missing drives, and no spare drive in the array is acting as a replacement for a failed drive.
•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, all drives in the array must be moved at the same time.
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
2.Power down the system.
3.Move the drives.
4.Power up the system. If a 1724 POST message appears, drive positions were changed successfully and the configuration was updated.
If a 1785 (Not Configured) POST message appears:
a.Power down the system immediately to prevent data loss.
b.Return the drives to their original locations.
c.Restore the data from backup, if necessary.
5.Verify the new drive configuration by running ORCA or ACU ("Configuring an array" on page 12).
Adding drives
You can add hard drives to a system at any time, as long as you do not exceed the maximum number of drives that the controller supports. You can then either build a new array from the added drives or use the extra storage capacity to expand the capacity of an existing array.
To perform an array capacity expansion, use ACU. If the system is using
