cpqFcaPhyDrvReads
Module: CPQFCA-MIB
OID (symbolic): CPQFCA-MIB::cpqFcaPhyDrvReads
OID (numeric): 1.3.6.1.4.1.232.16.2.5.1.1.10
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: External Array Physical Drive Sectors Read (low).
The phyDrvHReads and the phyDrvReads together shows the total number of sectors read from the physical disk drive during the reference time (phyDrvRefHours).
The actual number of sectors read equals the phyDrvHReads times 2^32 plus the phyDrvReads.
This information may be useful for determining rates. For instance, if you wanted to calculate the average number of reads 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 cpqFcaPhyDrvReads?
This counter provides the low-order 32 bits of the total sectors read from the physical drive during its reference time, to be combined with cpqFcaPhyDrvHReads for the full 64-bit total. An admin uses this figure, together with the reference hours counter, to estimate the read workload a specific disk is handling. For example, a rapidly increasing low-order Reads counter on one drive versus its neighbors could indicate uneven load distribution across the array.
