cpqDaPhyDrvHWrites
Module: CPQIDA-MIB
OID (symbolic): CPQIDA-MIB::cpqDaPhyDrvHWrites
OID (numeric): 1.3.6.1.4.1.232.3.2.5.1.1.12
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Sectors Written (high).
The phyDrvHWrites and the phyDrvWrites together shows the total number of sectors written to the physical disk drive during the reference hours (phyDrvRefHours).
The actual number of sectors written equals the phyDrvHWrites times 2^32 plus the phyDrvWrites.
This information may be useful for determining rates. For instance, if you wanted to calculate the average number of writes per hour of operation, divide this number by the reference hours.
What is cpqDaPhyDrvHWrites?
This integer holds the high-order component of a 64-bit sectors-written counter (equal to this value times 2^32 plus cpqDaPhyDrvWrites) accumulated over the drive's reference hours in cpqDaPhyDrvRefHours. An admin only needs this high-order value once the low-order sector-write counter has wrapped on an extremely busy drive. For example, this becoming nonzero on a drive under sustained heavy write load for years confirms the low-order phyDrvWrites counter has wrapped around.
