Advanced Menu in the SCU
The Advanced menu in the SCU allows you to lock/unlock resources and
view system resource assignments. To enter this menu, run the SCU and
select View or edit details (Step 3). Press F7 for the Advanced menu. A
description of each of the options in the Advanced menu follows.
Locking of Resources
The SCU allows you to lock resources for any EISA/PCI expansion board
installed in the server. This allows you to assign resources to that
expansion board (e.g. IRQ, Option ROM address), and then to keep those
resources assigned to that expansion board even if the SCU is rerun. This
is most frequently used to prevent the ROM address on the bootable
controller from being reassigned in the event that new expansion boards
are added to the server.
Enter the Advanced menu in the SCU.
The first item in this list is Lock/unlock boards. Press Enter to select. The
list of integrated and installed options is shown. Move to the option whose
resources you want to lock and press Enter. An exclamation point (!)
appears to the left of that option indicating that the resources associated
with that option have been fixed and will not change when the SCU is run.
To unlock the resource, press Enter again, and the exclamation point
disappears. Press F10 to complete this operation.
View Additional System Information
The SCU provides information to the user regarding resource assignments
and availability. Information on installed expansion boards, assigned and
available resources can also be viewed.
