Description: SCSI Physical Drive Sectors Read (high).
The phyDrvHighReadSectors and the phyDrvlowReadSectors together show the total number of sectors read from the physical disk drive during the service time (phyDrvServiceHours).
The actual number of sectors read equals the phyDrvHighReadSectors times 2^32 plus the phyDrvLowReadSectors.
This information may be useful for determining rates. For example, if you want to calculate the average number of reads per hour of operation, divide this number by the service time.
What is cpqScsiPhyDrvHighReadSectors?
This counter is the high-order 32 bits of a 64-bit total sector-read count for a physical drive, combined with the low-order counter via multiplying this value by 2^32. It lets monitoring software compute a drive's cumulative read volume over its service time for capacity and wear trending. For example, a busy database server's disk might accumulate enough reads that highReadSectors becomes nonzero, signaling the low counter alone has wrapped.
