Goal
This document details procedures for how to navigate between the various "shells" on a Sun Fire[TM] 3800, 4800, 4810, 6800, E4900, or E6900 Server's System Controller (SC).

 Video - How to navigate SC shells (5:00) 
Solution
Sun Fire 3800, 4800, 4810, 6800, E4900, and E6900 System Controller (SC) software contains multiple shells. Each have specific functionality regarding administration of the platform. The shells include:
- Domain Console (Solaris[TM] Operating Environment or OpenBoot PROM (OBP))
- Domain Shell
- Platform Shell
Refer to the above picture for an overview of navigation between the
Platform shell, Domain shell and Domain Console (from the Sun
Fire Midrange Systems Platform Administration Manual).
Definition of
Terms Used in Diagram:
Domain Console: The domain's
console device connection (/dev/console). When connected, the user
will have one of the following prompts:
- OpenBoot Prom (OBP)
- console login
Domain Shell: A shell on the
system controller with the ability to administer a specific domain
on the platform
Platform Shell:
A shell on the system controller with the ability to administer the entire platform
escape sequence: A set of
keystrokes which trigger the BREAK control character to be sent to
the system controller.
- Firmware 5.16.X or greater provides
the setescape/showescape commands which allow the user
to set the escape sequence.
- The default escape sequence is
#.
- Some applications have their own escape
sequence; see the application's manual for details. Here are
two examples:
- Solaris telnet: CONTROL-] (aka. ^])
- Solaris tip: ~#
NOTES:
To interrupt a domain running Solaris and bring it to the
OpenBoot PROM (OBP) ok prompt, issue the break command
from the Domain Shell. - The resume command will result in an ok prompt for the OpenBoot PROM (OBP) if Solaris is not
running on the domain. Otherwise, it will result in a console
login prompt.
- The disconnect command will only return to the
Platform Shell if the Domain Shell was obtained via the console command from the Platform Shell.
Otherwise it will disconnect the user from the system
controller.
To disconnect from the Platform Shell, issue the disconnect command. - If the connection to the system controller is made via the
serial port and the user does not issue a disconnect
when complete, the session on the serial port will remain open in
the state at which the user left it.
For firmware less than 5.16.X, if a sequence of applications
which all share the same escape sequence are run to connect to the
system controller, the first instance of the application will pick
up the BREAK control character sent via the escape sequence.
To ensure the correct application instance receives the BREAK
control character, an ESCAPE control character must be sent for each additional
instance in the sequence. For example, using Solaris
telnet: workstation% telnet admin_workstation
or
admin_workstation% telnet sunfire_sc0
Type 0 for Platform Shell
Type 1 for domain A console
Type 2 for domain B console
Type 3 for domain C console
Type 4 for domain D console
Input: 1
Enter password:
schostname:A> console A
hostname console login: ^] <- (send telnet sequence)
telnet> send escape
(If the above step is not taken, the user will be taken to the
workstation% prompt after running send break on the next step)
telnet> send break
schostname:A>
