Hi,

I am trying to install the Oracle Clusterware 10g as part of my RAC setup.
I have configured RHEL 4 in 2 nodes (rac and rac2). But when I run the runcluvfy utility, I get the below error:

[oracle@rac cluvfy]$ ./runcluvfy.sh stage -pre crsinst -n rac,rac2
Performing pre-checks for cluster services setup
Checking node reachability...
Node reachability check passed from node "rac".
Checking user equivalence...
User equivalence check failed for user "oracle".
Check failed on nodes:
rac
WARNING:
User equivalence is not set for nodes:
rac
Verification will proceed with nodes:
rac2

The problem is only with the first node(rac). The second node passes succesfully.
ssh works fine. Not sure what is wrong!

Thanks!
