Module: CPQFCA-MIB
OID (symbolic): CPQFCA-MIB::cpqFcaPhyDrvRecvReadErrs
OID (numeric): 1.3.6.1.4.1.232.16.2.5.1.1.16
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
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, run diagnostics.
If the value cannot be determined, 4,294,967,295 is returned.
What is cpqFcaPhyDrvRecvReadErrs?
This counter reports the number of read errors that were successfully corrected through the physical drive's own retry mechanism during the reference time. An admin monitors this because although occasional recovered errors are normal for any disk, a rapid increase in this value alongside hard read errors suggests the drive is beginning to fail. For example, a recovered read error count climbing sharply week over week on one specific drive would flag it as a replacement candidate before it produces uncorrectable errors.
