APAR status

  • Closed as program error.

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

  • NFS v3 mount fails if UDP is disabled on NetApp NFS server.
    

Problem conclusion

  • Currently AIX's portmapper calls clntudp_bufcreate() and
    creates an UDP socket. Fix ensures pmap_getport to try UDP and
    then TCP on failure.
    

Temporary fix
