Specifying SCSI Parameters
133
For each channel of the SCSI board, you need to note certain information. As an example, look at
the information for the SCSI interface (the first two bold lines). For each channel of this SCSI
interface, note the following information:
• Bus #—identifies the bus the device is on; for the SCSI interface, this is the same for both
channels. In this example, the bus number is 20.
• Dev #—the ID the device is assigned on the bus; for the SCSI interface, 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’s vendor ID; for the SCSI interface, this is the same for both
channels. For all the SCSI interface the ID is 0x1000.
• Device ID—shows the device ID; for the SCSI interface, this is the same for both channels. For
the SCSI interface the ID is 0x0030.
• 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 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)
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. From the EFI shell prompt, type the following command to obtain the controller’s handle for the
SCSI interface:
devtree
A tree of all EFI-capable devices installed in the system displays. The output looks like this:
Shell> devtree
