Description: Physical Drive Size in MB.
This is the size of the physical drive in megabytes. This value is calculated using the value 1,048,576 (2^20) as a megabyte. Drive manufacturers sometimes use the number 1,000,000 as a megabyte when giving drive capacities so this value may differ from the advertised size of a drive. This field is only applicable for controllers which support SCSI drives, and therefore is not supported by the IDA or IDA-2 controllers. The field will contain 0xFFFFFFFF if the drive capacity cannot be calculated or if the controller does not support SCSI drives.
What is cpqDaPhyDrvSize?
cpqDaPhyDrvSize reports a physical drive's capacity in megabytes, calculated using 1,048,576 bytes per megabyte rather than the 1,000,000-byte convention drive makers often use for advertised capacity, and only applies to controllers supporting SCSI drives. Because of that calculation difference, an admin should expect this SNMP-reported size to read slightly lower than the number printed on the drive's label. For instance, a drive marketed as 300 GB might report a slightly smaller MB figure here purely due to the binary-versus-decimal megabyte difference, not because of any fault.
