• No more than 32 logical volumes are configured for a controller.
• The array must be in its original configuration with no active spare drives.
• Capacity expansion is not running.
• Controller firmware is the latest version (recommended).
• Controller is a Smart Array controller.
Before moving an array from one controller to another, observe these additional
requirements:
• All drives in the array must be moved at the same time.
• Drive positions of the destination controller must match original drive positions.
When all requirements are met:
1. Power down the system. Refer to “System Power Down” in Chapter 3.
2. Move the drives. Refer to “Hot-Plug SCSI Hard Drive Options” in Chapter 3.
3. Power up the system. Refer to “System Power Up” in this chapter.
A #86 controller display message should appear, indicating that drive positions
were changed and the configuration was updated. If a #121 controller display (no
volumes) message is displayed, power down the system immediately to avoid
data loss, and return the drives to their original locations.
For more information about display messages, refer to Appendix C, “Display
Messages.”
4. Check the new drive configuration by running ACU. Refer to the HP Array
Configuration Utility User Guide on the Documentation CD.
