Are any counted against the CPU? If there are errors, check the errorlog. Try DIAGNOSE or Compaq Analyze. Also check SHOW CPU/FULL for clues.<BR /><BR /> If you can't find anything, log a hardware case with your local Customer Support Centre.

This node has 4 CPU's. I tried START/CPU 3 and it first went into INIT then back to TIMOUT. What can be possible causes and how can I check for errors?
