APAR status
Closed as fixed if next.
Error description
If customer decides to disable UDP on NFS server for security reasons or else, NFSv3 mount on AIX NFS client fails as UDP protocol is required by default for portmapper.
Local fix
Use NFSv4
Problem summary
Changes are in a very common code path, and changes are risky since it changes the pmap_getport routine which is a very basic function called during mount call, Hence it is recommended only for development releases. This is a very rare case this issue will occure only if server disables UDP for portmapper which is a very rare case.
Problem conclusion
Temporary fix
