Description: Physical Drive SCSI Bus Number.
The bus number indicates to which SCSI bus this physical drive is attached. The first instance is one and increments for each SCSI bus on a controller. A value of -1 will be returned if the physical drive is attached to a controller that does not support multiple SCSI busses. This is not supported by the IDA, IDA Expansion, or IDA-2 controllers. For SAS and SATA drives, the bus number corresponds to the enclosure where the drive resides.
What is cpqDaPhyDrvBusNumber?
cpqDaPhyDrvBusNumber identifies which SCSI bus a physical drive is attached to, starting at one and incrementing per bus on the controller, with -1 returned on controllers that don't support multiple SCSI buses; the description notes SAS and SATA drives handle bus numbering differently. This lets an admin pinpoint exactly which channel a given drive sits on when troubleshooting bus-wide issues like the resets tracked by cpqDaPhyDrvBadTargetErrs. For example, if bus faults are isolated to bus number 2, an admin would focus diagnostics on the cabling and drives attached to that specific bus.
