Need a simulator of Isilon onefs 7.1

Hi Team,

        I have a doubt regarding isilon commands as there is a version conflict. I think, some commands executed in servers version 7 and 9 are different. For example,  to list a network interface,

version 7: " isi network list interface " and

version 9:  "isi network interface list" .And also, i'm confused whether listing smb shares (isi smb shares list) command works in both the versions. To check this, i need a simulator of version 7 . I haven't found any download page regarding this. plaese do the needful.
