Description: SCSI Physical Drive Recovered Read Errors.
This is the number of read requests that the drive had to use retries or other recovery mechanisms on to recover data during the service time (phyDrvServiceHours).
Retry corrected reads will occasionally occur over time. Having a large number of retry 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 similiar drives as a precaution.
What is cpqScsiPhyDrvRecvReadErrs?
This counter tracks read requests where the drive needed retries or other recovery mechanisms (short of full ECC correction) to successfully return data, over its service time. Occasional recovered reads are considered normal wear, but the count is still useful for comparing relative drive health within an array. For example, an admin auditing several disks might flag the one with a much higher recvReadErrs count for closer monitoring.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.232.5.2.4.1.1.18 snmpwalk -v2c -c public <target> CPQSCSI-MIB::cpqScsiPhyDrvRecvReadErrs
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.232.5.2.4.1.1.18.1 snmpget -v2c -c public <target> CPQSCSI-MIB::cpqScsiPhyDrvRecvReadErrs.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cpqScsiPhyDrvRecvReadErrs.1
