cpqDaPhyDrvReads
Module: CPQIDA-MIB
OID (symbolic): CPQIDA-MIB::cpqDaPhyDrvReads
OID (numeric): 1.3.6.1.4.1.232.3.2.5.1.1.11
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: 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.
What is cpqDaPhyDrvReads?
This integer holds the low-order component of a 64-bit sectors-read counter (equal to phyDrvHReads times 2^32 plus this value) accumulated over the drive's reference time in cpqDaPhyDrvRefHours, useful for calculating rates like average reads per hour. An admin trends this counter to understand read load distribution across the physical drives in an array, spotting a hot drive receiving disproportionate traffic. For example, an admin compares cpqDaPhyDrvReads across all drives in a logical volume to confirm reads are evenly striped rather than concentrated on one disk.
