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
