SUMMARY: SUN E220R - panic[cpu0]/thread=10408000: cpu 2 failed to start (2)

Thanks to everyone who responded to my issue.

The solution I used was to wait for the SUN tech to replace the faulty CPU.
After the CPU was replaced the system booted up clean and my database issues
cleared up.

Here were some other suggestions:

>If you cannot boot then your only option here is to remove the complaining
cpu

>If the machine boots, you can disable a CPU using psradm.  There is a
OBP equivalent but I don't recall what it is.   You could also pull
the CPU from the chassis, but that is more work (although you would
need to in order to replace the CPU anyway, but then you would be
opening it up twice).

>Don't know about removing the CPU but can you bring it up to single
user mode and try running 'psradm -f' - you'll need to pass the cpu to
take off line as an argument.

ISSUE:
I have a dual processor SUN E220R running Solaris 8 with latest patches.
The box has been running with no issues but this morning my Informix
database crashed hard.  I brought the Informix database back online and it
crashed about 2 hours later.  I also noticed that when I ran the uptime
command I got a "Segmentation Fault".  I then decided to reboot the server.
After the system was sync'd and rebooted, it failed to reboot.  I got an
"Instruction access exception" and panic[cpu0]/thread=10408000: cpu 2 failed
to start (2).

I have called SUN support and I am waiting on a Site Engineer to respond.
Can I just remove the second cpu and reboot the system?

I have tried several commands to take the second cpu offline but cannot find
an OBP command that will work.

Any help would be appreciated.

Thanks
