1. Ensure that all system and storage system cables are intact and seated properly. You may
need to replace cables.
2. Check the physical proximity of the system to other electrical devices. Since electrical
noise may cause a glitch error, check the AC circuit for other electrical devices.
3. If you continue to receive many of these errors, replace the drive.
NOTE: If the drive has not failed, the above counts simply provide a cumulative record of past
errors that have been corrected.
Failure Indicators
Use the Failure Indicators to determine the cause of a drive failure. Typically, the number of failures
is zero when the drive is operating normally. If a counter is not zero and the drive has not failed,
there could be an intermittent problem that may require the drive to be replaced.
The Failure Indicators are:
•
Spinup Errors—When the physical drive fails due to the failure of a spin-up command, a
Spinup Error occurs. If the failure count is not zero and the drive has failed, replace the drive.
If the counter is not zero and the drive is OK (has not failed), there may be an intermittent
problem that requires drive replacement. If you observe that the count is increasing over time,
replace the drive.
•
Aborted Commands—The Aborted Commands counter records the number of times that a
physical SCSI drive returned an Aborted Command status when a SCSI command was
attempted. This error count indicates unsuccessful termination of the SCSI command. When
the physical drive is failed due to aborted commands that could not be retried successfully,
Aborted Commands errors occur. If the number of errors is not zero and the drive has failed,
replace the drive.
If the counter is not zero and the drive is OK (has not failed), there may be an intermittent
problem that requires drive replacement. If you observe that the count is increasing over time,
replace the drive.
•
Reallocation Aborts—When the physical drive is failed due to an error that occurred when
the controller was trying to reallocate a bad sector, a Reallocation Abort error occurs.
Because of the nature of magnetic disks, certain sectors on a drive may have media defects.
The reallocation area part of the drive is set aside to compensate for these defects. The array
controller writes information addressed from unusable sectors to available sectors in the
reallocation area.
If the number of reallocation abort errors is not zero and the drive has failed, replace the
drive. If the counter is not zero and the drive is OK (has not failed), there may be an intermittent
problem that requires drive replacement. If you observe that the count is increasing over time,
replace the drive.
•
Media Failures—When this physical drive fails due to unrecoverable media errors, a Media
Failure occurs.
If the number of media failure errors is not zero and the drive has failed, replace the drive. If
the counter is not zero and the drive is OK (has not failed), there may be an intermittent
problem that requires drive replacement. If you observe that the count is increasing over time,
replace the drive.
•
Format Errors—When a format operation fails because the controller was unable to remap a
bad sector, a Format Error occurs.
If the number of format errors is not zero and the drive has failed, replace the drive. If the
counter is not zero and the drive is OK (has not failed), there may be an intermittent problem
that requires drive replacement. If you observe that the count is increasing over time, replace
the drive.
