System Controller Navigation Procedures
There are two types of connections: telnet and serial. If you are using a telnet connection, configure the system controller network settings before using telnet.You can access the system controller main menu using either the telnet or serial connections.
1. Obtain the system controller main menu by typing telnet schostname (CODE EXAMPLE 2-1).
The system controller main menu is displayed. CODE EXAMPLE 2-1 shows how to enter the platform shell.
The system controller prompt, schostname:SC>, is displayed for the platform shell of the main system controller. If you have a redundant SC configuration, the spare system controller prompt is schostname:sc>.
1. Obtain the system controller main menu by typing telnet schostname (CODE EXAMPLE 2-2).
CODE EXAMPLE 2-2 shows entering the shell for domain A.
The system controller prompt for the domain shell you connected to is displayed. CODE EXAMPLE 2-2 shows entering the shell for domain A, whose prompt is
3. If the domain is active (the domain keyswitch is set to on, diag, or secure which means you are running the Solaris operating environment, or are in the OpenBoot PROM), perform the following steps:
b. At the telnet> prompt type send break (CODE EXAMPLE 2-3).
If the domain is active and the domain keyswitch is set to on, diag, or secure (you are running the Solaris operating environment, are in the OpenBoot PROM, or are running POST), perform the following steps:
CODE EXAMPLE 2-4 shows obtaining the shell for domain A from the domain console. Because the domain is active, you will not see a prompt.
To return to the originating shell, use the disconnect command. In a domain shell, to connect to the domain console, use the resume command. To connect to a domain shell from the platform shell, use the console command.
FIGURE 2-1 shows how to navigate between the platform shell, the domain shell, the domain console by using the console and disconnect commands. FIGURE 2-1 also shows how to connect to both the domain shell and platform shell from the operating environment by using the telnet command.
In the telnet command in FIGURE 2-1, 5000 is the platform shell and
Caution - Note that in FIGURE 2-2, typing the break command suspends the Solaris operating environment.
FIGURE 2-3 illustrates how to navigate between the OpenBoot PROM and the domain shell. This figure assumes that the Solaris operating environment is not running.
When you connect to a domain, you will be connected to the domain shell unless the domain is active, in which case you will be connected to the domain console. When you connect to the console, you will be connected to the Solaris operating environment console or the OpenBoot PROM, depending on which of these is currently executing.
The domain console is available only when the domain is active. To make the domain active, you must turn the keyswitch on. You will be automatically switched from the domain shell to the domain console.
This action powers on and initializes the domain. The domain will go through POST and then the OpenBoot PROM. If the OpenBoot PROM auto-boot? parameter of the setupdomain command is set to true, the Solaris operating environment will boot. For details on the domain parameters, refer to the setupdomain command description in the Sun Fire 6800/4810/4800/3800 System Controller Command Reference Manual.
1. Press and hold the CTRL key while pressing the ] key to get to the telnet> prompt (CODE EXAMPLE 2-5).
Note - If you have a connection to the domain initiated on the platform shell, you must type disconnect twice.
3. Type ~. to end your tip session (CODE EXAMPLE 2-6).
