For each channel of the SCSI board, note certain information. For example, look
at the information for the SCSI interface. For each channel of this SCSI interface,
note the following information:
Bus #: Identifies the bus the device is on. This is the same for both channels.
In this example, the bus number is 20.
Dev #: Identifies the ID the device is assigned on the bus. This is the same
for both channels. In this example, the SCSI interface is device 01.
Fnc #: Identifies the channel of the device (00 for channel A, 01 for channel
B, and so on). In this example, because the SCSI interface has two channels,
one channel is 00 and the other is 01.
Vendor ID: Shows the device vendor ID. This is the same for both channels.
For all SCSI interfaces, the ID is 0x1000.
Device ID: Shows the device ID. This is the same for both channels. In
this example, the SCSI interface the ID is 0x0030.
Slot #: Identifies the physical card slot in the system where the SCSI
interface is installed. This is the same for both channels. In this example,
the SCSI interface is on the system board, therefore the slot number is xx.
Path: Identifies the device path. 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 this example, the combined information
that tells you this is a SCSI interface are the following (shown in bold, for
highlighting purposes):
00 20 01
00 20 01
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.
2. From the EFI Shell prompt, enter the following command to obtain the controller
handle for the SCSI interface:
devtree
A tree of all EFI-capable devices installed in the system displays. For example:
