Description: SCSI Physical Drive ECC Corrected Read Errors (high).
This is the number of read requests that the drive had to use an Error Correction Code (ECC) algorithm on to recover data during the service time (phyDrvServiceHours).
ECC corrected reads will occasionally occur over time. Having a large number of ECC corrected errors does not necessarily indicate that the drive is failing. However, you may wish to replace a drive with an abnormally high amount in comparison to other similar drives as a precaution.
What is cpqScsiPhyDrvEccCorrReads?
This counter tracks read requests where the drive had to invoke its ECC algorithm to recover the data successfully, over the drive's service time. A modest number of these occurring over time is normal and doesn't necessarily mean the drive is failing, though a high rate may still justify a precautionary replacement. For example, an admin comparing eccCorrReads across otherwise-identical drives might replace the one with an abnormally high count as a preventive measure.
