Failure Of Another Drive During Rebuild; Recovering From A Power Failure Reported From The Backplane - HPE D6020 Maintenance And Service Manual

The amount of unused capacity on the drives
The number of drives in the array (for RAID 5 and RAID 6 with ADG)
Allow approximately 1 minute per gigabyte for the rebuild process to be completed.
System performance is affected during the rebuild, and the system is unprotected against further
drive failure until the rebuild has finished. Therefore, replace drives during periods of low activity
when possible.
CAUTION:
glows, or if other drive LEDs in the array go out, the replacement drive has failed and is producing
unrecoverable disk errors. Remove and replace the failed replacement drive.
When automatic data recovery has finished, the Online LED of the replacement drive stops
flashing 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, reboot the node. The system may 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.

Recovering from a power failure reported from the backplane

The flashing LED pattern is indication of power failure reported from the backplane. To recover:
1. Simultaneously press and hold the Power button and the flashing UID button until the power
button LED is solid amber (after approximately 4 seconds).
2. If Step 1
other UID button.
48 Troubleshooting the system
If the Online LED of the replacement drive stops blinking and the amber Fault LED
did not work, repeat the step, except press and hold the Power button and the
