Sun Microsystems T6300 manual Alom sc Prompt

Page 24

The prompt displayed on the terminal or shell tool indicates which channel you are accessing:

■The # or % prompt indicates that you are at the system console and that the Solaris OS is running.

■The ok prompt indicates that you are at the system console and that the server is running under OpenBoot firmware control.

■The sc> prompt indicates that you are at the ALOM system controller.

Note – If no text or prompt appears, it might be that no console messages were recently generated by the system. If this happens, pressing the terminal’s Enter or Return key should produce a prompt. If the ALOM session has timed out, pressing the terminal’s Enter or Return key might not be effective. In that case, it might be necessary to issue the escape sequence, #. (Hash-Period), to return to ALOM.

To reach the system console from the ALOM system controller,

■Type the console command at the sc> prompt.

To reach the ALOM system controller from the system console,

■Type the system controller escape sequence.

By default, the escape sequence is #. (Hash-Period).

For more information about communicating with the ALOM system controller and system console, see the following:

■“Communicating With the Server” on page 1

■“ALOM sc> Prompt” on page 10

■“OpenBoot ok Prompt” on page 12

ALOM sc> Prompt

The ALOM system controller runs independently of the server module and regardless of system power state. When you install the server module, the ALOM system controller immediately starts up and begins monitoring the system.

You can log in to the ALOM system controller at any time, regardless of system power state, as long as you have a way of interacting with the system. The sc> prompt indicates that you are interacting with the ALOM system controller directly. The sc> prompt is the first prompt you see when you log in to the system through the serial port or network management port.
