Description: SCSI Physical Drive Sectors Written (high).
The phyDrvHighWriteSectors and the phyDrvlowWriteSectors together show the total number of sectors written to the physical disk drive during the service time (phyDrvServiceHours).
The actual number of sectors read equals the phyDrvHighWriteSectors times 2^32 plus the phyDrvLowWriteSectors.
This information may be useful for determining rates. For example, if you want to calculate the average number of writes per hour of operation, divide this number by the service time.
What is cpqScsiPhyDrvHighWriteSectors?
This counter is the high-order 32 bits of a 64-bit total sector-write count for a physical drive, combined with the low-order counter via multiplying this value by 2^32. It helps track cumulative write volume on a disk for wear analysis, particularly relevant on drives with limited write endurance. For example, on a heavily-written log volume, highWriteSectors climbing from zero indicates the drive has now written more than 4 billion sectors' worth of data.
