Hard Drive Installation and Replacement - 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. IMPORTANT: There are some restrictions on moving an array: • A drive array that has been moved from a battery-backed array controller to one that is not battery-backed can no longer undergo RAID/stripe size migration, array capacity expansion, or logical drive capacity extension. • Do not move an array that is configured with RAID ADG to a controller that does not support RAID ADG. Only controllers that support RAID ADG can recognize a drive array that has this configuration. When 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 is not battery backed.

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.
IMPORTANT:
There are some restrictions on moving an array:
•
A drive array that has been moved from a battery-backed array controller to one that is not
battery-backed can no longer undergo RAID/stripe size migration, array capacity
expansion, or logical drive capacity extension.
•
Do not move an array that is configured with RAID ADG to a controller that does not
support RAID ADG. Only controllers that support RAID ADG can recognize a drive array
that has this configuration.
When 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 is not
battery backed.
