start /CH/BL#/SP/cli

Just getting a T5220 out of the box, the auto-boot? parameter is set to true.
This means that one does not have access to the ok prompt when powering up the server the first time.
Due to the new release of iLOM, the break command does not end on the ok prompt.

According to Sun documentation one can send a graceful shutdown (init 0)
to get to the ok prompt. The following menu is then displayed:

-> set /HOST/bootmode script="setenv auto-boot? false"
Set 'script' to 'setenv auto-boot? false'

-> set /HOST send_break_action=break
Set 'send_break_action' to 'break'

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y
Serial console started.  To stop, type #.

Switching between ALOM and ILOM shells

Here are the commands needed to switch between the ALOM and ILOM shells on the T5xx0 SPARC CMT servers. I’m saving this here because I can never easily find it when I go searching Google or docs.sun.com for it.

ILOM -> ALOM
sc> userclimode admin default
sc> logout

ALOM -> ILOM
-> set /SP/users/admin cli_mode=alom
-> exit
