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 storage systems.
Before you move drives, the following conditions must be met:
• 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.
