Solaris

Hi,

So what if any output do you see when you do a poweron from the ALOM?

Hi gull04,


Thanks for your ongoing patience with this thread!


I'm not at the machine, but off the top of my head `poweron:





About the fans, one fan failure message was a CPU fan, I removed that CPU entirely as I believe the system should work with only 1 CPU anyway. There was also one chassis fan failure. Again I don't think that would stop the system booting. (I have spares which I will fit if I can get the system to boot).


IIRC, once the system is in the poweron state, `console -f` should give an 'ok>' prompt after hitting 'console -f' (and enter twice).



I can get you the exact ALOM messages later when I'm at the system.

I replaced the fans on the CPU.


The console output looks like this:

Code:

sc> poweron
sc> 
SC Alert: SC System booted.

sc> console -f
Enter #. to return to ALOM.

SC Alert: VOLTAGE_SENSOR @ MB.BAT.V_BAT has exceeded low warning threshold.

I can hit enter as many times as I like, but no 'ok' prompt.


If the CPU were bad, the ALOM would know, right?

I also tried resetting nvram, and provideing a bootscript like:

Code:

setenv output-mode ttya

no cigar.

Hi,

Can you show the output of sc> showlogs and sc> showenvironment - I seem to remember reading that the button battery either a CR2025 or a CR2032 I think shouldn't make a difference if it fails. But that there had been instances of being unable to get the server powered on.

I'll get you the output from those commands later when I'm at the machine again.


And I'll get a new battery in case that is the issue!


Thanks

Hi Vext01,

The battery may not be the issue - although I'm sure that it's not helping in any way. From memory there was a SUN document published (Probably about 10 Years ago) that mentioned issues with the ALOM when the battery was discharged. It shouldn't have made any difference as the settings were all stored in NVRAM, but the flat battery could cause unpredictable behaviour (or something like that ).

I'd like to give this some more attention, but I'm preparing loads of stuff or auctioning things for a sequence of "Disaster Rehearsals" - so can only be here and active when the Auditors and Business Users are off patting themselves on the back!

Regards

Hi Gull,


I've replaced the battery and it hasn't helped, I'm afraid.


Any last ideas before I source a new mainboard?


Cheers

Hi Guys,

I've read this discussion with interest. My one comment is that, AFAIR, the default ALOM userid/password combination for this series of SPARC is either admin/changeme or, on later models, root/changeme

And, yes, the means of resetting the ALOM password is to install Solaris (or boot a 'live' DVD) and use 'scadm' command.

Without successfully logging into the ALOM it won't let you do much.
