Utilities Specifying SCSI Parameters • Slot #-identifies the physical card slot in the system where the SCSI interface is installed; for the SCSI interface, this is the same for both channels. In this example, the SCSI interface is on the system board therefore the in slot number is xx. • Path-identifies the device's path; for the SCSI interface, this is the same for both channels. In this example, the SCSI interface path is Acpi(HWP0002,200)/Pci(1|0) for channel A and Acpi(HWP0002,200)/Pci(1|1) for channel B. Using the SCSI interface information from the example above, the pieces of information that, combined, tell you this is a SCSI interface are the following (shown in bold, for highlighting purposes): 00 20 01 00 0x1000 0x0030 xx Acpi(HWP0002,200)/Pci(1|0) 00 20 01 01 0x1000 0x0030 xx Acpi(HWP0002,200)/Pci(1|1) Looking at all of the above information together, the vendor (0x1000) and device (0x0030) are the IDs for a SCSI interface. Of the devices with those IDs, this device has two channels (Fnc # of 00 immediately followed by Fnc # of 01). Also, this SCSI interface has a non-numeric (XX) slot # indicating that it is on the system board. Step 2.

Specifying SCSI Parameters

•
Slot #
—identifies the physical card slot in the system where the SCSI interface is installed;
for the SCSI interface, this is the same for both channels. In this example, the SCSI interface is
on the system board therefore the in slot number is
xx
.
•
Path
—identifies the device’s path; for the SCSI interface, this is the same for both channels. In
this example, the SCSI interface path is
Acpi(HWP0002,200)/Pci(1|0)
for channel A and
Acpi(HWP0002,200)/Pci(1|1)
for channel B.
Using the SCSI interface information from the example above, the pieces of information that,
combined, tell you this is a SCSI interface are the following (shown in
bold
, for highlighting
purposes):
00
20
01
00 0x1000 0x0030
xx
Acpi(HWP0002,200)/Pci(1|0)
00
20
01
01 0x1000 0x0030
xx
Acpi(HWP0002,200)/Pci(1|1)
Looking at all of the above information together, the vendor (
0x1000
) and device (
0x0030
) are the
IDs for a SCSI interface. Of the devices with those IDs, this device has two channels (Fnc # of
00
immediately followed by Fnc # of
01
). Also, this SCSI interface has a non-numeric (XX) slot #
indicating that it is on the system board.
Step 2.
Still at the EFI shell prompt, type this command to obtain the controller’s handle for the SCSI
interface:
devtree
A tree of all EFI-capable devices installed in the system is displayed. The output could look like
this:
