Ctrl[95] LSI Logic Ultra160 SCSI Controller
Ctrl[0A] Acpi(HWP0002,700)
Ctrl[96] Acpi(HWP0002,700)/Pci(1|0)
Ctrl[97] Acpi(HWP0002,700)/Pci(1|1)
Ctrl[98] Acpi(HWP0002,700)/Pci(2|0)
In the above example, this SCSI board's information is shown in bold, for highlighting purposes.
You can tell the information is for this SCSI board because the path on the first
line—Acpi(HWP0002,200)— is the HBA's path from the information displayed by the info io
command. The next two lines are for the SCSI board's two channels, one line for each channel (they
contain the SCSI board's description [LSI Logic Ultra160 SCSI Controller]). Note the value shown for
Ctrl—82 and 83—at the beginning of each of those lines; this is the controller's handle for that
channel. You need to know it for the next step.
NOTE
Step 3. Still at the EFI shell prompt, type this command to obtain the EFI driver's handle for the SCSI
card:
drvcfg
A list of all EFI-capable configurable components in the system is displayed. The output may look
like this:
Drv[26] Ctrl[79]
Drv[34] Ctrl[83]
Drv[35] Ctrl[82]
Drv[36] Ctrl[92]
Drv[37] Ctrl[91]
Drv[38] Ctrl[95]
Drv[71] Ctrl[7D]
Drv[71] Ctrl[7E]
This listing shows which driver controls which device (controller). In the above example, this SCSI
board's information is shown in bold, for highlighting purposes. You can tell the information is for
this SCSI board because the values shown for Ctrl—82 and 83—are the controller's handles for the
SCSI board's two channels (from the information displayed by the devtree command).
NOTE
TIP
Step 4. Using the information (the driver's handle [Drv] and the controller's handle [Ctrl]) from the
drvcfg command, start the EFI SCSI Setup Utility for one channel of this SCSI board. Still at the
EFI shell prompt, type this command:
drvcfg -s drvr_handle cntrl_handle

The EFI driver's handle values will change on every boot.
From this command (drvcfg), we recommend you record these two pieces of
information for each channel of each SCSI board HBA you want to change the SCSI
parameters for:
• Drv (the EFI driver's handle)
• Ctrl (the controller's handle)
