Hard Drive Installation and Replacement 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 is no longer able to undergo RAID/stripe size migration, array capacity expansion, or logical drive capacity extension. • If an array that is configured for RAID ADG is moved to a controller that does not support RAID ADG, it will not be recognized by the new controller. Before moving drives, these conditions must exist: • 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. After verifying that the preceding conditions exist: 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. 2. Power down the system. 3. Move the drives. 4. Power up the system. A 1724 POST message is displayed, indicating that drive positions were changed and the configuration was updated. CAUTION: If a 1785 (Not Configured) POST message is displayed, power the system down immediately to avoid data loss, and then return the drives to their original locations. 5. Restore the data from backup if necessary. D-10 Compaq Smart Array 5i Plus Controller and Battery Backed Write Cache User Guide

•
If an array that is configured for RAID ADG is moved to a controller that does not support
RAID ADG, it will not be recognized by the new controller.
Before moving drives, these conditions must exist:
•
The move will not result in more than 14 physical drives per channel.
