2-6Guidelines for Making Changes to Current Installation

Moving Drives

CAUTION: Back up all data before removing drives or changing configurations. Failure to do so could result in permanent loss of data.

Drives can be moved to alternate ID positions on the same array controller. (For information on moving arrays from one controller to another, see the “Moving Arrays” section in this chapter.) Although data loss is not anticipated during drive movement, Compaq recommends that you back up data before moving drives. To move drives, the following conditions must be met:

■System power is OFF (includes all system components).

■The move will not result in more than 30 physical drives or 15 physical drives per SCSI bus and/or 32 logical drives (volumes) connected to a single controller.

■No failed drives are identified. The array should be in its original configuration with no active spare drives.

■Capacity expansion is not running.

■Controller firmware is the latest revision (recommended).

When the above conditions are met, follow these steps to move drives:

1.Power-down the System.

2.Move drives.

3.Power-up the system. A 1724 POST message should indicate that drive positions were changed and the configuration was updated. If a 1785 (Not Configured) POST message is displayed, turn the system OFF immediately to avoid data loss and return the drives to their original locations.

4.Run the Array Configuration Utility to view the new drive configuration (optional).
