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:

Shell> devtree
