Working with Solaris Server Consoles using LOM/ ILOM/ ALOM/ ELOM/ RSC

Access Server’s OS Console from the LOM service Processor:

Server Models : SunFire V100/V120/V1280/E2900 and Netra 1280/1290
You can use below command to navigate between Server OS console and LOM port:
connecting to console from LOM prompt:
sc/lom>console
Returning to LOM from the Server console
presss #. ( # followed by a dot)
How to send break signal to console so that we can launch the server at OK> Prompt:
sc/lom>break – server will be landed into ok prompt


Access Server OS Console from SUN ALOM Service Controller :

Server Models : Sun Fire V125, V210, V240, V245, V250, V440, V445, Netra 210, 240, 440 …
Once you connect to the ALOM port, you can use below commands. Please note that any time you want to exit the serial console just press  ‘#.’ ( # followed by dot) you will return to ALOM.
SC > console
Console session already in use. [view mode]
Enter #. to return to ALOM.
(Press #.)
SC > console -f
Warning: User currently has write permission to this console and forcibly removing them will terminate any current write actions and all work will be lost. Would
you like to continue? [y/n]y
Enter #. to return to ALOM.

SC> break  

Access Server’s OS Console from SUN ILOM Service Processor:

Server Models:Sun Fire X4100, X4100 M2, X4140, X4150, X4170, X4200, X4200 M2, X4250, X4270, X4600, X4600 M2 … 
Once you connect to ILOM SP you can use below command to connect to the console. Please note you can use “ESC ( ” to disconnect from console any time, then you will return to ILOM.
-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y
Serial console started.
To stop, type ESC (  (Press Enter key to view serial console) in case if you notice that serial console is already in use just stop it once and restart.
-> stop /SP/console
Are you sure you want to stop /SP/console (y/n)? y
How to send break signal to console so that we can launch the server at OK> Prompt:
-> set /HOST send_break_action=break
and then
-> start /SP/console


 Access Server’s OS Console from ELOM  Service Processor:

Server Models : Sun Fire X2100, X2100 M2, X2200, X2200 M2
Once you connect  to ELOM SP port you can user below commands to start and stop the consoles. Please note that you can use  ESC ( to disconnect from the serial console anytime, then you will return to ELOM. 
/SP -> start /SP/AgentInfo/console
console activate successful
press ESC ( to terminate session…
in case if you notice the Serial console is already in use you can stop it with below command and start it again
/SP -> stop /SP/AgentInfo/console
console de-activate successful

-> set /HOST send_break_action=break
and then
-> start /SP/console

 
Access console from RSC Service Processor

Server Models: Sun Fire v480, Sun Fire V490, Sun Fire v880, Sun Fire V880z and Sun fire V890
Once you connect to RSC Service Processor, you can use below command to navigate betweek OS console and RSC prompt.
RSC> console    <- it will take you to the Server OS console
anytime if you want to return to the RSC prompt from the OS console just press “~.”  ( tilda’~’ followed by a dot ‘.’)incae if the escape character “~” not working you can find it from the OS level using the command
# /usr/platform/`uname -i`/sbin/rscadm show escape_char
escape_char=”*”
if you think someone already using console, or console is busy you can still grab the console by resetting RSC which will forcibly close all the current connection
rsc> resetrsc
or from OS console prompt
#/usr/platform/`uname -i`/sbin/rscadm resetrsc

How to send break signal to console so that we can launch the server at OK> Prompt:
RSC >break – server will be landed into ok prompt
