NOTE:
A SAS drive in RAID mode is identified by "Scsi" in the device path A SAS drive in HBA mode is
identified by “SAS” in the device path.
NOTE:
Unlike parallel SCSI, you cannot correlate UEFI device paths to internal SAS disk drive bays with
SAS regardless of RAID/HBA mode. The UEFI device paths currently do not contain any
information that could be used to determine the physical location of the drives.
