You should turn on CVU tracing and look at the trace output. Its not very pretty nor concise, but it's the only option I can think of..... Check the CVU FAQ on Metalink for turning on tracing- I think its setting up a few environment variables. What stumps me is 'user equivalence check' failing- and I can never figure out exactly what test is being performed and what failed. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Ethan Post Sent: Tuesday, September 25, 2007 3:17 PM To: oracle-l Subject: cluvfy -verbose not very verbal $ cluvfy comp nodecon -n foo, foo1 -verbose Verifying node connectivity Verification of node connectivity was unsuccessful on all the nodes. I can ssh from both nodes to foo, foo1, foo-priv and foo1-priv without being prompted by anything. So I expect the above to work, but it says there was a failure, thank goodness for verbose mode or I probably wouldn't even know that! Any ideas on what to do to trouble shoot this? Thanks, Ethan
