cpqFcaPhyDrvHReads
Module: CPQFCA-MIB
OID (symbolic): CPQFCA-MIB::cpqFcaPhyDrvHReads
OID (numeric): 1.3.6.1.4.1.232.16.2.5.1.1.9
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: External Array Physical Drive Sectors Read (high).
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 cpqFcaPhyDrvHReads?
This counter provides the high-order 32 bits of the total sectors read from the physical drive during its reference time, to be combined with cpqFcaPhyDrvReads (the low-order bits) by multiplying this value by 2^32. An admin uses the combined 64-bit count to calculate read throughput rates on drives that have accumulated more reads than a single 32-bit counter can hold. For example, a nonzero HReads value on a busy drive indicates it has processed billions of sector reads over its lifetime, requiring the two counters together for an accurate total.
