SGI: Hardware

Hi all,

My TEZRO with IP59-PIMM had not started up Power On Diagnostic because of subjected reason.

Some days ago, my TEZRO came to be stopped and reported "TLB refilll exception" error many times.
When I checked status of components from PROM console(issued enableall or so),
system had suddenly stopped that reason, and after re-plug power cable, POD stopped staring up.
(The reason of TLB refill error may trouble of DIMMs.
Because when I inspected the DIMMs, I found some ceramic capcitor had removed from component side of DIMMs.
Now these DIMMs group had removed.)

When I issued "pwr u" from L1 console, fans, Hdds are spinned up, but POD is not started up.
And issued "leds" after that, system reported following messages.

001c01-L1>leds
CPU A: 0x9a: FLED_DISABLED: CPU is disabled by env variable.
CPU B: < CPU not present >
CPU C: 0x9a: FLED_DISABLED: CPU is disabled by env variable.
CPU D: < CPU not present >

Ofcause, all CPUs enabled in L1 level.

001c01-L1>cpu
CPU Present Enabled

0A 1 1
0B 0 0
0C 1 1
0D 0 0

I had also reflashed L1 firmware from software L2 emulator, but could not re-enable.

Here is my logs and related infomations.

The reason of this error is some strange data had written to PROM or NVRAM because of brokened DIMM, I think.
Does anyone have any solution to re-enable the CPUs?
And sorry for my poor English, I'm not native speaker.

You probably did this already but just in case : did you do an < enableall > from the prom ?

Out of curiosity, is this a deskside Tezro or a rackmount ?

Thank you for your reply.

Unfortunately, I have not tried "enableall" from PROM console.
Because PROM could not started up due to CPU disabled problem.
I'm also tried entering PROM console (console mode <Ctrl + D>) from L1,
system reported "no response from 001c01" and no PROM's POD message displayed.

And my TEZRO is a deskside one.

Okay, this won't help you much but maybe give you some hope ...

I did something similar once with some bad memory. POST disabled the memory slots due to the bad memory so I switched them into the other memory slots, so the computer could disable all the memory. ( Fuel )

After that it didn't want to boot

I did manage to fix it via some hardware-switching and using the L1 so you should be able to do the same.

Sorry I can't be more exact : Oldtimer's is hell.


Cool. I was just wondering if it was the rackmount that was on yahoo auctions. I'm still kicking myself for not buying that

Hi!



Try moving the DIMMs from slots 4,6,5,7 into slots 0,2,1,3.

Then if you can get into the PROM, type "enableall", followed by "update", and finally "reset".

Thank you for your kind advice.

I tried moving DIMMs and powered up, but PROM does not start up.

I had also tried all DIMMs removed, but same resulted, PROM could not start runnning.
(If PROM starts normally, PROM's POD should report "no DIMMs error" in such a case, I think.)

Did you read this thread: viewtopic.php?f=3&t=7894 ?

Do you get any kind of prompt when you power up the system ('pwr u') after it print the message about disabled CPUs?

You may have to set the virtual dip switches to boot the system into POD or CAC mode instead of booting the regular PROM. Then, from there, the 'clearallogs / initalllogs / flush / reset' sequence mentioned in the link above (and other places on this board).

Sorry, I don't have a link handy to the virtual debug switch documentation. If nobody can help you with those I can dig a little deeper.

That's a good idea.

Type "debug 0x10d" in the L1 console to do that. This will disable power-on diagnostics, enable verbose output, enable booting directly into POD mode, and most importantly: ignore disabled CPUs and memory.

Once in POD mode, type "go cac" and the commands jan-jaap suggested. Before you enter "reset" in POD mode, type "dbg 0" to disable the debug switches (you can also escape to the L1 prompt and type "debug 0" for the same effect).

After the system restarts, you might still need to do "enableall", "update", and "reset" within the PROM.

Thank you for your valuable advice.
My TEZRO's CPU now seems to be re-enabled.

I had read the article you suggested,
but I did not consider that procedure is available for my environment.
(Because TEZRO is O3000 based architecture, in contrast contents of article is O2000)

I tried some commands that you suggested.

Here is my procedure.
