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 handle values change on every boot.
3. From the EFI Shell prompt, enter the following command to obtain the EFI driver's
handle for the SCSI interface:
Shell> drvcfg
A list of all EFI-capable configurable components in the system is displayed. For
example:
Shell> drvcfg
Configurable Components
Drv[3D] Ctrl[15] Lang[eng]
Drv[3F] Ctrl[19] Lang[eng]
Drv[45] Ctrl[1C] Lang[eng]
Drv[45] Ctrl[1D] Lang[eng]
This listing shows which driver controls which device (controller). This information
describes a SCSI interface because the values shown for Ctrl—17 and 18—are
the controller handles for the SCSI interface two channels (from the information
displayed by the devtree command).
NOTE: The EFI driver handle values change on every boot.
TIP: From this command (drvcfg), record these two pieces of information for
each channel of each SCSI interface for parameters to be changed:
Drv (the EFI driver handle)
Ctrl (the controller handle)
4. Using the drivers handle [Drv] and the controller handle [Ctrl] from the drvcfg
command, start the EFI SCSI Setup Utility for one channel of this SCSI interface.
At the EFI Shell prompt, enter:
Shell> drvcfg -s drvr_handle cntrl_handle
where
drvr_handle The handle of the driver that controls the channel with the
SCSI ID you want to display or change
