Module: CPQSCSI-MIB
OID (symbolic): CPQSCSI-MIB::cpqScsiPhyDrvLowWriteSectors
OID (numeric): 1.3.6.1.4.1.232.5.2.4.1.1.14
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: SCSI Physical Drive Sectors Written (low).
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 cpqScsiPhyDrvLowWriteSectors?
This counter is the low-order 32 bits of a 64-bit total sector-write count for a physical drive, paired with cpqScsiPhyDrvHighWriteSectors for the full total. It's used for calculating write-activity rates on a given disk over its service hours. For example, an admin might graph lowWriteSectors over time to confirm that write load is evenly spread across the drives backing a striped volume.
