Problem conclusion

• Add validation checks for internal data structures
  to identify from which AIX Major release mount operation
  is triggered from. In nimadm cached environment, mount command
  of 72 Level may be triggerd in AIX 73 Level NIM Server, if
  mount operation is used in post migration phase.
