Using the Boot Selection Menu program

The Boot Selection Menu program is a built-in, menu-driven configuration utility program that you can use to temporarily redefine the first startup device without changing settings in the Setup utility.

To use the Boot Selection Menu program, complete the following steps:

1. Connect a keyboard, monitor, and mouse to the console breakout cable, and connect the console breakout cable to the compute node.
2. Turn on the compute node (see Turning on the compute node).
3. Press F12 (Select Boot Device). If a bootable USB mass storage device is installed, a submenu item (USB Key/Disk) is displayed.
4. Use the Up Arrow and Down Arrow keys to select an item from the Boot Selection Menu and press Enter.

The next time the compute node starts, it returns to the startup sequence that is set in the Setup utility.

Note

If no functioning boot device is available, the system would shut down automatically after 50 failed booting attempts.
