Module: CPQFCA-MIB
OID (symbolic): CPQFCA-MIB::cpqFcaPhyDrvHardReadErrs
OID (numeric): 1.3.6.1.4.1.232.16.2.5.1.1.15
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, run diagnostics to verify that a problem exists.
If the value cannot be determined, 4,294,967,295 is returned.
What is cpqFcaPhyDrvHardReadErrs?
This counter reports the number of read errors on the drive that could not be corrected by the drive's own Error Correction Code or by retries, accumulated during the reference time. An admin watches this counter increase over time as a sign that a problem may exist with the physical drive itself. For example, a hard read error count that jumps from zero to a nonzero value between polling cycles would prompt the admin to schedule diagnostics on that disk.
