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.
