In the above 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 Ultra160 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 will change on every boot.
3. Still at the EFI shell prompt, type this command to obtain the EFI driver’s handle for the
SCSI interface:
drvcfg
A list of all EFI-capable configurable components in the system is displayed. The output
may look like this:
Shell> drvcfgConfigurable ComponentsDrv[3D] Ctrl[15] Lang[eng]Drv[3F] Ctrl[19]
Lang[eng]Drv[45] Ctrl[17] Lang[eng]Drv[45] Ctrl[18] Lang[eng]
This listing shows which driver controls which device (controller). In the above example,
the SCSI interface information is shown highlighted bold. You can tell the information is
for this SCSI interface because the values shown for Ctrl—17 and 18—are the controller’s
handles for the SCSI interface two channels (from the information displayed by the devtree
command).
