cpqDaPhyDrvThrRecvWriteErrs is the factory-set maximum threshold for recovered write errors on a physical drive during its reference time window, corresponding to the cpqDaPhyDrvRecvWriteErrs counter. This threshold lets management software distinguish the normal background rate of recovered write errors from a rate serious enough to warrant attention. For example, an admin would only escalate a drive's recovered write error trend once it actually approaches or crosses this specific threshold value.
