CU menus such as Select Boot Drive, Select Adapter, and Logical Drive menus will completely or partially close when a drive is inserted or removed.

If a Rebuild is in progress when you insert or remove a drive, the CU will first display the message Rebuilding Of Drive Not Complete! Press Esc.. followed by the hot plug message. If the Rebuild was not affected by this hot plug event, it will continue to rebuild from where it left off, provided that Auto Resume is enabled; otherwise, Rebuild will start over from the beginning. If the rebuilding array was affected by the hot plug event, the Rebuild will abort and the array status will change based on the hot plug operation.

If an Initialization is in progress when you insert or remove a drive, the CU will display the message Initialization of Array Not Complete! Press ESC.. followed by the hot plug message.

If a consistency check is in progress when you insert or remove a drive, the CU will display the message CC Not Completed! Press ESC.. followed by the hot plug message.

3-6 Checking Data Consistency

The Check Consistency feature can be used on RAID 1 or RAID 10 logical drives to verify the data consistency between the mirrored physical drives. The MegaRAID BIOS CU automatically corrects any differences found in the data when a consis- tency check is run. Follow these steps to check consistency:

1.On the Management Menu select Check Consistency and press Enter. A list of configured logical drives is displayed.

2.Highlight a logical drive with the arrow keys.

3.Press the spacebar to select the logical drive to check for consistency.

Note: If you select a RAID 0 logical drive, a message appears stating that a Check Consistency cannot be performed. To continue, deselect the logical drive, highlight a redundant logical drive, and press the spacebar again.
