HP Integrity BL860c i2, BL870c i2 & BL890c i2 Server Blade User Service Guide

Drive paths in UEFI
Devices in the server blade 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.
