cpqFcaPhyDrvWrites
Module: CPQFCA-MIB
OID (symbolic): CPQFCA-MIB::cpqFcaPhyDrvWrites
OID (numeric): 1.3.6.1.4.1.232.16.2.5.1.1.12
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Sectors Written (low).
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.
If the value cannot be determined, 4,294,967,295 is returned.
What is cpqFcaPhyDrvWrites?
This counter provides the low-order 32 bits of the total sectors written to the physical drive during its reference hours, to be combined with cpqFcaPhyDrvHWrites for the full total. An admin tracks this to estimate write-intensive workload on a given disk, useful for identifying drives under heavier duty cycles than others in the same array. For example, comparing Writes counts across all physical drives in a logical volume can reveal an unbalanced write pattern worth investigating.
