HP Integrity cx2600 Maintenance Manual page 95

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 devtree command to obtain the controller's handle
for the SCSI interface.
A tree of all EFI-capable devices installed in the system displays. For example:

This information describes 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 describe the SCSI interface two channels, one line for each channel. The
lines contain the SCSI interface description [LSI Logic Ultra160 SCSI Controller].
The value shown for Ctrl—17 and 18 at the beginning of each line is the controller's handle
for each channel. You need this value for the next step.
NOTE:
The controller's handle values change on every boot.
3. From the EFI Shell prompt, enter the drvcfg command to obtain the EFI driver handle for
the SCSI interface.
A list of all EFI-capable configurable components in the system is displayed. For example:
Shell> drvcfg
