Specifying SCSI Parameters
104
• Vendor ID—shows the device’s vendor ID; for the SCSI board, this is the same for both channels. For all
SCSI board HBAs, the ID is 0x1000.
• Device ID—shows the device’s device ID; for the SCSI board, this is the same for both channels. For all
SCSI board HBAs, the ID is 0x0021.
• Slot #—identifies the physical card slot in the system where the HBA is installed; for the SCSI board, this is
the same for both channels. In this example, the HBA is in slot 03.
• Path—identifies the device’s path; for the SCSI board, this is the same for both channels. In this example, the
HBA’s path is Acpi(HWP0002,200)/Pci(1|0) for channel A and Acpi(HWP0002,200)/Pci(1|1) for
channel B.
Using the SCSI board’s information from the example above, the pieces of information that, combined, tell you
this is a SCSI board are the following (shown in bold, for highlighting purposes):
00 40 01 00 0x1000 0x0021 03 Acpi(HWP0002,200)/Pci(1|0)
00 40 01 01 0x1000 0x0021 03 Acpi(HWP0002,200)/Pci(1|1)
Looking at all of the above information together, the vendor (0x1000) and device (0x0021) are the IDs for a SCSI
board. Of the devices with those IDs, this device has two channels (Fnc # of 00 immediately followed by Fnc # of
01). Also, this SCSI board has a numeric (non-XX) slot # (03, in this example).
Step 2. Still at the EFI shell prompt, type this command to obtain the controller’s handle for the SCSI card:
devtree
A tree of all EFI-capable devices installed in the system is displayed. The output could look like this:
