Hi we have 2 e450's of similar spec.

Basically one of them died, so we decided to take out the processors all 4 of them and fit them into another box. They are 200mhz sparc ii processors.

However I can only get one of them to show in psrinfo. I have gone throught installation properly by following this doc
any ideas what i am doing wrong?

lsi# uname -a
SunOS lsi 5.8 Generic_117350-02 sun4u sparc SUNW,Ultra-4
lsi# psrinfo
0 on-line since 05/14/08 14:56:38
lsi# psrinfo -v
Status of processor 0 as of: 05/14/08 16:53:15
Processor has been on-line since 05/14/08 14:56:38.
The sparcv9 processor operates at 200 MHz,
and has a sparcv9 floating point processor.

there is an env setting to disable upa slots. I have in the past seen these set where a cpu slot would not be probed when booting the OS. see sun info doc 18357.

also here is the jist of it;

Set the upa-noprobe-list to 0 :

At the OK prompt....

OK setenv .upa-noprobe-list 0
OK reset-all


That's it, all 4 cpu's should now show up with psrinfo or prtdiag.

NOTE:
Depending on the version of OBP on an e250/450, the upa-noprobe-mask variable may be named differently. It may be seen in one of the following forms:

upa-noprobe-list
upa-noprobe-mask

On the latest versions of OBP it is a hidden variable

.upa-noprobe-mask

You will need to use printenv -a at the OK prompt to see this variable with the most current version of OBP. Although the name of the variable has changed a couple of times, its' function remains the same.

If printenv -a does not return anything then try running the following command from the ok prompt:

ok printenv .upa-noprobe-mask

Note: This variable (upa-noprobe-list) can also be viewed and changed from Solaris using the eeprom command.

Thanks

Isn't there also directives to disable a CPU? I've done this before where a CPU went bad.
 
Hi thanks for reply.

I tried all three at obp but command was not recognised.

Any ideas?

Scunningham99;

Couple questions;

1) can you post a printenv output

2) you did move the dc to dc converters over correct? I have to ask this question but am sure you did.

3) Does the banner show all 4 cpu's at the OBP level?

Thanks
