Description: Recovered Read Errors.
This shows the number of read errors corrected through physical drive retries during the reference time (phyDrvRefTime).
Over time, all disk drives produce these errors. If you notice a rapid increase in the value for Recovered Read Errors (or Hard Read Errors), a problem may exist with the drive. The value increases every time the physical drive detects and corrects another error.
Expect more Recovered Read Errors than Hard Read Errors. If you suspect that a problem may exist with the drive, schedule server down time to run diagnostics.
What is cpqDaPhyDrvRecvReadErrs?
cpqDaPhyDrvRecvReadErrs tracks read errors that the physical drive successfully corrected through its own retry mechanism during the reference time period, as opposed to hard read errors it could not recover. Because all disk drives generate some recovered read errors over their lifetime, a slow steady increase is normal, but a rapid spike alongside hard read errors signals a drive heading toward failure. As an example, an admin comparing this counter week over week on an aging drive would treat a sudden tenfold increase as the trigger to schedule a proactive drive swap.
