Switching Between the ALOM System Controller and the System Console

If the system console is directed to the virtual-console device (its default configuration), the serial port and the network management port provide access to both the system console and the ALOM system controller (see FIGURE 1-1).

FIGURE 1-1Switching Between ALOM System Controller and System Console

If the system console is configured to use the virtual-console device, when you connect through one of these ports you can access either the ALOM command-line interface or the system console. You can switch between the ALOM system controller and the system console at any time, but you cannot access both at the same time from a single terminal or shell tool.
