Drive paths in UEFI
Devices in the server are represented by device paths in the UEFI shell. Each internal SAS drive
could be configured either as:
• RAID mode
• HBA (raw) mode
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.
