When automatic data recovery has finished, the online LED of the replacement drive stops blinking

and begins to glow steadily.

Failure of another drive during rebuild

If a non-correctable read error occurs on another physical drive in the array during the rebuild

process, the Online LED of the replacement drive stops blinking and the rebuild abnormally

terminates. If this situation occurs, restart the server. The system might temporarily become

operational long enough to allow recovery of unsaved data. In any case, locate the faulty drive,

replace it, and restore data from backup.

Handling disk drive failures

If the controller was configured with hardware fault tolerance, complete the following steps after

a disk drive failure:

1. Determine which physical drive failed. On hot-plug drives, an amber drive failure LED

illuminates.

2. If the unit containing the failed drive does not support hot-plug drives, perform a normal

shutdown.

3. Remove the failed drive and replace it with a drive that is of the same capacity. For hot-plug

drives, after you secure the drive in the bay, the LEDs on the drive each flash once in an

alternating pattern to indicate a successful connection. The online LED flashes, indicating that

the controller recognized the drive replacement and began the recovery process.

4. Power on the server, if applicable.

5. The controller reconstructs the information on the new drive, based on information from the

remaining physical drives in the logical drive. While reconstructing the data on hot-plug drives,

the online LED flashes. When the drive rebuild is complete, the online LED is illuminated.
