HP Integrity rx4640 Server - Manual (Page 94)

Hard Drive Installation and Replacement
• Do not remove a second drive from an array until the first failed or missing drive
has been replaced and the rebuild process is complete. (When the rebuild is
complete, the Online LED on the front of the drive stops blinking.)
There are some exceptions:
— In RAID ADG configurations, any two drives in the array can be replaced
simultaneously.
— In RAID 1+0 configurations, any drives that are not mirrored to other
removed or failed drives can be simultaneously replaced offline without data
loss.
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). However, if you combine arrays that were on different controllers
into one larger array on a single controller, the data on the arrays is lost.
Before moving drives, these conditions must be met:
•
•
•
•
•
•
The move will not result in more than 14 physical drives per channel.
No more than 32 logical volumes will be configured for a controller.
No drives are failed or missing.
The array is in its original configuration with no active spare drives.
Capacity expansion is not running.
Controller firmware is the latest version (recommended).
If moving an array, all drives in the array must be moved at the same time.
