Special thanks to Darren for exchanging several personal e-mails of trying to
lead me in finding the solution.
Some userful commands are:
prtdiag
psrinfo
Some useful system documentation:
Solution:
After looking into all the info, I was still puzzled to identify the cpu1 which
is in question.
Then I decide to search the sunsolve and here is the info I found:
The order of CPU installation is not the same as the way the O/S numbers the
CPUs.
O/S probes the UPA slots from top to bottom (UPA slot
1=TOP 4=BOTTOM)
UPA slot 1 = CPU 0 J0101
UPA slot 2 = CPU 1 J0201
UPA slot 3 = CPU 2 J0301
UPA slot 4 = CPU 3 J0401
If system panics on bootup or keeps rebooting with RED
STATE EXCEPTION
and a CPU is a suspect disable one CPU at a time.
At the ok prompt:
ok setenv upa-port-skip-list <CPU#>
ok boot
Once the Failing CPU is found system should boot up with
the CPU
disabled. When CPU is replaced set the NVRAM variable back
to original setting.
ok setenv upa-port-skip-list none
you can find above info on the NET at:
http://sunsolve.sun.com/private-cgi/retrieve.pl?doc=srdb%2F21220&zone_32=e450%20cpu
So to my cpu1 panic message, the CPU1 is the J0201 and it is on second slot.

=============================
Here is the original question:
To All Helpers:
I have an E450 system with three CPUs in it running Solaris 2.6. Recently it
crashed with Panic[cpu1] error message indicating the Ecache SRAM data parity
error.
I have got a new CPU to replace, after looking into the Server Owner's Guide, I
am kind of puzzle about which CPU this panic message indicated and which CPU
should I pull.
Could anyone give me some tip on this?
Thanks,
Zion
Here is the part of messages file when system was rebooted:
