Module: CPQIDA-MIB
OID (symbolic): CPQIDA-MIB::cpqDaPhyDrvHardReadErrs
OID (numeric): 1.3.6.1.4.1.232.3.2.5.1.1.16
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Hard Read Errors.
This shows the number of read errors that have occurred on a drive that could not be recovered by a physical drive's Error Correction Code (ECC) algorithm or through retries during the reference time (phyDrvRefTime). Over time, a disk drive may produce these errors. If you receive these errors, a problem may exist with your drive.
The value increases every time the physical drive detects another error.
The severity of these errors depends on whether the monitored system is running in a fault tolerant mode. With fault tolerance, the controller can remap data to eliminate the problems caused by these errors. In either case, if you see an increase in these errors, schedule server down time to run diagnostics to verify that a problem exists.
What is cpqDaPhyDrvHardReadErrs?
cpqDaPhyDrvHardReadErrs counts read errors on a physical drive that its own Error Correction Code and retry logic could not recover during the reference time window. A rising count here is a direct sign the drive's magnetic media or read head is degrading, since healthy drives should log few or none of these permanent read failures. For instance, if a technician watches this counter climb steadily on one disk in an array over several days, that pattern points to that specific drive needing replacement before it drops data entirely.
