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.
Hardware Errors—The Hardware Errors counter records the number of times that a physical
SCSI drive returned a Hardware Error status when a SCSI command was attempted. This
error status indicates unsuccessful termination of the SCSI command. The controller typically
retries this command several times before failing the drive.
If the number of hardware 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.
Not Ready Errors—When a physical drive returns a not ready status when it should be
ready, a Drive Not Ready Error occurs. This error could occur if a drive spins down
unexpectedly or if the drive never becomes ready after the spin up command is issued.
If the number of not ready 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.
Bad Target Errors—When a physical drive performs an action that does not conform to the
SCSI-2 port protocol, the SCSI port is reset.
If the number of bad target 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.
