Using ILOM on T5120/T5220

Default Service Processor (SP) Username/Password

 Username: root
 Password: changeme

Changing the default SP password

 set /SP/users/root password

Sending a Break to the OS

So the boot PROM on T2 processor based systems works very differently. As the boot PROM code is shared by the base OS with any LDOM's that may be present. As such, the boot PROM code is loaded into memory on startup of the hardware, or the LDOM, and then dropped. So it's not always running as it is on older systems. So in order to break to the boot PROM you need to do the following:

1. From the SP, send the break:

 set /HOST send_break_action=break

2. From the SP, start the console

 start /SP/console

3. At the console, you will see the following prompt:

 c)ontinue, s)ync, r)eset?

You want to reset, so:

 c)ontinue, s)ync, r)eset? r

4. Type #. to break out of the console and back to the SP.

5. Send the break signal again to force the boot PROM to break and stop at the OK prompt

 #.
 set /HOST send_break_action=break

6. Now start the console again to get to the OK prompt.

 start /SP/console

Seem overly complicated to you? I think so too!! Oh and you need to be quick about it, as the system is rebooting and will continue to do so unless you send that break in then you want it.
