User Service Guide, Third Edition - HP Integrity rx4640 Server

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 I/O baseboard.
2. To obtain the controller’s handle for the SCSI interface, enter the devtree command at the
EFI shell prompt.
A tree of all EFI-capable devices installed in the server displays. The output could look like
this:

In the preceding example, the SCSI interface information is shown highlighted bold. You
can tell the information is for the SCSI interface because the path on the first
line—Acpi(HWP0002,100)— is the path from the information displayed by the info io
command. The next two lines are for the SCSI interface two channels, one line for each
channel (they contain the SCSI interface description [LSI Logic Ultra320 SCSI
Controller]). Note the value shown for Ctrl—17 and 18—at the beginning of each of
those lines; this is the controller’s handle for each channel. You need to know it for the next
step.
NOTE: The controller’s handle values change on every boot.
3. to obtain the EFI driver’s handle for the SCSI interface, enter the drvcfg command at the
EFI shell prompt.
