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 changes 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[17] Lang[eng]
Drv[45] Ctrl[18] 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's handles
for the SCSI interface two channels (from the information displayed by the devtree command).
NOTE: The EFI driver's 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's handle)
Ctrl(the controller's handle)
