Operations Guide, Fourth Edition - HP Integrity rx1620

• 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.
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:
