HP Smart Array P830 User Manual page 24

CAUTION: Because data rebuild time operates at the rate of 200GB/15 minutes, the system
could be unprotected against drive failure for an extended period during data recovery or a
drive capacity upgrade. When possible, perform rebuild operations only during periods of
minimal system activity.
When automatic data recovery has finished, the drive status LED changes from flashing green to solid
green.
If the drive status LED on the replacement drive changes to flashing or solid amber, the rebuild process
has terminated abnormally.
If an abnormal termination of a rebuild occurs, identify the cause and appropriate corrective steps in
"Abnormal termination of a rebuild (on page 24)."
Abnormal termination of a rebuild
If the activity LED on the replacement drive permanently ceases to be illuminated even while other drives
in the array are active, the rebuild process has terminated abnormally. The following table indicates the
three possible causes of abnormal termination of a rebuild.
Observation
None of the drives in the array have an
illuminated amber drive status LED.
The replacement drive has an
illuminated amber drive status LED.
One of the other drives in the array
has an illuminated amber drive status
LED.
Each of these situations requires a different remedial action.
Case 1: An uncorrectable read error has occurred.
Back up as much data as possible from the logical drive.
1.
CAUTION: Do not remove the drive that has the media error. Doing so causes the logical
drive to fail.
Restore data from backup. Writing data to the location of the unreadable sector often eliminates the
2.
error.
Remove and reinsert the replacement drive. This action restarts the rebuild process.
3.
If the rebuild process still terminates abnormally:
Delete and recreate the logical drive.
1.
Restore data from backup.
2.
Case 2: The replacement drive has failed.
Verify that the replacement drive is of the correct capacity and is a supported model. If these factors are
not the cause of the problem, use a different drive as the replacement.
Case 3: Another drive in the array has failed.
A drive that has recently failed can sometimes be made temporarily operational again by cycling the
server power.
Power down the server.
1.
Remove the replacement physical drive (the one undergoing a rebuild), and reinstall the drive that it
2.
is replacing.
Power up the server.
3.
If the newly failed drive seems to be operational again:
Cause of rebuild termination
One of the drives in the array has
experienced an uncorrectable read error.
The replacement drive has failed.
The drive with the illuminated amber LED
has now failed.
