Solution  1011808.1 :   Sun Enterprise [TM] e250/450 only shows 3 out of 4 CPU's under psrinfo or prtdiag  


PreviouslyPublishedAs
216174

Symptoms
psrinfo and/or prtdiag shows only 3 of 4 CPU's installed on
a Sun Enterprise [TM] e250/450

Resolution
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.

The document doesn't need further update. It is used in the Poirot rulesets for E250/E450 as
systemboard/cpu replacement preventer.

comment : This document is perfect and is the same as 17716.
I suggest this one stay and 17716 be removed but they
are duplicates.
