if certain types of processor cards are installed in the system, this menu remains not applicable. for other types of processor cards, this menu will be active after the first boot as notes below.

    the first time the system is booted after nvram is cleared, not applicable displays under l3 mode menu on the screen. this may also happen if the service processor is replaced, or the processor cards are upgraded.

    if option l3 is selected when not applicable is on the screen, the system responds with not applicableand redisplays the system information menu. the setup menu can be displayed after the l3 mode is set, which happens the first time the system is rebooted.

    the default l3 mode is set by firmware during ipl. the default mode, private or shared, provides the optimum performance for hardware configuration of the system. the l3 mode is systemwide; it cannot be set on a per-partition basis.

    you can override the default setting by using the l3 mode menu. the l3 mode menu is similar to the following:

   

    selecting option 1 allows you to toggle between private and shared mode.
