• The amount of unused capacity on the drives
• The number of drives in the array (for RAID 5 and RAID ADG)
Allow approximately 15 minutes per gigabyte for the rebuild process to be
completed. This figure is conservative; the actual time required is usually less
than this.
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.
When automatic data recovery has finished, the Online/Activity LED of the
replacement drive stops blinking steadily at 1 Hz and begins to either glow
steadily (if the drive is inactive) or flash irregularly (if the drive is active).
CAUTION: If the Online/Activity LED on the replacement drive
does not light up while the corresponding LEDs on other drives in the
array are active, the rebuild process has abnormally terminated. The
amber Fault LED of one or more drives might also be illuminated. Refer
to "Abnormal termination of a rebuild (on page
34 )" to determine what
action you must take.
Abnormal termination of a rebuild
If the Online/Activity LED on the replacement drive permanently ceases to be
illuminated even while other drives in the array are active, the rebuild process
has abnormally terminated. The following table indicates the three possible
causes of abnormal termination of a rebuild.
Observation Cause of rebuild termination
None of the drives in the array have
an illuminated amber Fault LED. One of the drives in the array has
experienced an uncorrectable read error.
The replacement drive has an
illuminated amber Fault LED. The replacement drive has failed.
One of the other drives in the array
has an illuminated amber Fault LED. The drive with the illuminated Fault LED
has now failed.
Each of these situations requires a different remedial action.
Case 1: An uncorrectable read error has occurred.
