To Use Ilom Set /Host Send_Break_Action=Break, Start /Sp/Console Commands, Or Break Key - Sun Oracle Netra T5440 Administration Manual

You can also perform a graceful system shutdown from the ILOM service processor
command prompt using the stop /SYS command.
▼ To Use ILOM set /HOST send_break_action=
break, start /SP/console Commands, or Break Key
When it is impossible or impractical to shut down the system gracefully, you can get
to the ok prompt, if you have an alphanumeric terminal attached to the server, by
pressing the Break key.
1. Type set /HOST send_break_action=break to force a running Sun Netra
T5440 server to drop to a menu:
-> 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 #.
2. Press the Enter key
The server responds with:
c)ontinue, s)ync, r)eboot, h)alt?
3. Type c to get OpenBoot firmware control.
When init 0 is used, the server drops to this menu:
r)eboot, o)k prompt, h)alt?
From this menu, you can type o to get OpenBoot firmware control.
If the operating system is already halted, you can use the start /SP/console
command instead of set /HOST send_break_action=break to reach the ok
prompt.
Note – After forcing the system into OpenBoot firmware control, be aware that
issuing certain OpenBoot commands (such as probe-scsi, probe-scsi-all, or
probe-ide) might hang the system.
Note – These methods of reaching the ok prompt will only work if the system
console has been redirected to the appropriate port. For details, see
