Unhappy Sun Blade 2000 power on problem


Hi,

I seem to be having a problem with my Sun Blade 2000 workstation. Obviously I know there's a hardware forum, but it seems more likely someone here might be able to help with this one.

I powered down my workstation, and added a new 73GB FC-AL disk internally, powered the system back on and booted into Solaris 9. Unfortunately, when running the format command, the new disk wasn't seen. I powered the system down and removed the new disk, closed up the case and powered back on.

Now I get the power be applied to the system, I hear the drive spinning up (which is the 73GB FC-AL disk that has been in the system ever since I had it) then I get a single tone via the internal speaker and the machine powers off.

All I'm getting on the serial console before the system removes power is ths:

Code:
CPU seeprom format: 0000.0000.0000.0002
I've had a look at the Service Manual on docs.sun.com and not really found anything that looks like this problem - my best guess is it's related to the CPU module. The CPU module is the 1.2GHz UltraSPARC III CU module. Anyone else seen this before or got any ideas?

Cheers,
Steve

Hi SteveK1979,

You may need to check your PSU, try the following;

Unplug the power cord from the PSU, wait 10 minutes and re-connect the power cord to the PSU, if the system powers off, you may need to replace the PSU, (Power Supply Unit).

I hope this is of help.

Hi,

Thanks for the reply. I did manage to get the machine up and running, and once booted it seemed to be absolutely fine. I didn't spot anything obviously wrong from prtdiag etc.

This is the only slightly suspicious thing so far:
Code:
============================ Environmental Status=======================
Fan Speeds:
---------------------------------------------
Location * * * Sensor * * * * *Status * Speed
---------------------------------------------
+stem-fan-slot system-fan * * *okay * * 19% * * * * * *
+/cpu-fan-slot cpu-fan * * * * okay * * 19% * * * * * *
+r-supply-slot power-supply * *okay * * 100% * * * * * *

Temperature sensors:
-----------------------------------------------------------------------------
Location * * * Sensor * * * * Temperature *Lo * LoWarn *HiWarn * *Hi *Status
-----------------------------------------------------------------------------
+em-board/cpu0 Die * * * * * * *77C * * * -10C * *0C * * 88C * * 90C *okay
+em-board/cpu0 Ambient * * * * *22C * * * -10C * *0C * * 40C * * 60C *okay
Power supply fan being listed at 100% speed - that doesn't seem quite
right. I'm sure it was listed like that before though, but I can't completely remember.

I tried to switch to runlevel 0 to take the machine down to firmware and the OpenBoot console to run some hardware diagnostics, and it seems this is where problems started again. The system seemed to shut down to the OpenBoot console, however I couldn't seem to do anything via a serial console. This may be a problem with my serial cables though.

After a short while, perhaps 60 seconds, the system powered off. I have not been able to get it running again since. I removed power as you suggested, and I can power the machine on with the same results as described above (system powers up, appears to start POST, I see the CD-Rom light come on, hear the hard drive spin up, then it powers off again) so if you've got any more ideas, or if the above output looks wrong please let me know.

I am wondering if it might be worth taking the power supply out and putting it back, making sure all the cables are connected properly etc. as per the procedure in the service manual.

Cheers,
Steve

YES! carry out a re-seating of the PSU, but I would suggest obtaining and replacing the PSU.

I hope this is of help.

Any time you install a new piece of hardware under solaris, you need to do a reconfiguration reboot, and run devfsadm.


reboot -r

Hi Kahless,

Thanks for your reply. I've had a read of the link you posted and I see where you're coming from, however I was under the impression that a reconfigure reboot wouldn't be required in this case.

I thought that Solaris should pick up the disk as effectively it's just another drive that has been added to an existing fibrechannel loop, the same as if you had inserted a new disk into an external array acting as a JBOD, only the shelf in this instance happens to be inside the case of the machine? I could be completely wrong about that of course.

More pressing right now though is getting the thing to power on reliably.

Cheers,
Steve

you ALWAYS need a reconfiguration reboot when adding hardware on solaris.

and I am sorry, I gave you the wrong syntax. its reboot -- -r

running devfsadm when the system comes up from said reboot is a good best practice as well. Its redundant if everything works properly, but 10% of the time it is nesseary, and it never hurts anything.



Unlike Linux, Solaris DOES NOT automatically probe for new hardware on every boot.
