BCH Main Menu Commands and Submenus
The following sections provide information and examples of the submenus and commands in

Boot Command
Use the BO (boot) command to initiate the boot sequence from any menu in the interface. You
can enter either a default or specified path to the boot device. This path must be the definition
of a device, for example, FWSCSI.6.0 or PRI. The default is PRI.
Path Command
The PA (path) command displays or sets the current paths. Invoked with only one argument, PA
displays the current path of the entity passed as argument. For example, path alt displays the
current alternative boot path, and path pri fwscsi.6.0 sets up the primary boot path as
the device attached to SCSI controller with ID 6 and LUN 0. You can also set and display the
paths of console (graphics/serial) and keyboard. For example:
Main Menu: Enter command or menu > pa
Primary boot path: intscsia.1
