Version of HACMP and type of configuration (IPAT / IP Aliases) will make a difference here but ...

Can you ping the IP addresses for prod1 from prod2?

Check that all the IP names for prod1 are defined in the HACMP config

Check that all the IP names for prod1 are in /etc/hosts

I did that once basically deallocating and reinstalling damaged /took about a day/ node and then setting back into cluster /i do not recommend doing that if you ever has any use of HACMP/
HACMP is very sensitive to DNS failures, so is AIX's libc.
