IBM AIX client fails to connect to Red Hat Storage over NFS protocol.

Issue

• AIX clients unable a to mount a RHS share over NFS by using below mount command

  # mount -o vers=3,proto=tcp 10.65.200.166:/testvol /tmp/gluster
  

• Able to mount when port=38467 option is specified, however some files/folders are no longer visible after certain OS operation like cd,ls.

  # mount -o vers=3,proto=tcp,port=38467 10.65.200.166:/testvol /tmp/gluster
  

• How can AIX clients mount a RHS share over NFS without specifying the port option.

• Native NFS shares are not having any issues and can be mounted without specifying the port option.
