In this post, we will see the commands for accessing the serial console of different kinds of Sun servers based on ALOM, ILOM, ELOM and other IPMI based Service Processors like V20z/V40z.

1. Accessing Serial console of ALOM systems
2. Accessing Serial console of ILOM systems
3. Accessing Serial console of ELOM systems
4. Accessing Serial console of V20z/V40z IPMI based Service Processors

1. Accessing Serial console of ALOM systems (like Sun Fire V125, V210, V240, V245, V250, V440, V445, Netra 210, 240, 440)

1.1 Logon to the SC.

1.2 Use console command for serial console access or console -f to force writing if the console is in read-only mode.

Hi Prasanna,
I have a Sun T5120 running Solaris10
I want to access the SP console, but donot have a serial-eth cable to connect to the SER MGT port.

My question is,
. Is there anyway to reach the
/SP/console prompt from inside the OS
Is there a Break command?
. I have ssh access to system through NICs
