  3. Entry in /etc/fstab should be as below on RHEL server if you want to mount /cdunix from AIX server on RHEL server at mount point /ABCD.
    =====================================
    [root@RHEL /]# cat /etc/fstab | grep /ABCD
    AIX:/cdunix /ABCD nfs defaults,nfsvers=3 0 0
    ======================================
    nfsvers=3 makes the difference

    1. This seems to be a different error . Have you made the relevant entries in the server tnsa033 ?
