Also Abhishek, run lsdev command on AIX and see if you are able to DFC devices on AIX, the output should be something like this:
DDdfc Available Data Domain DDdfc Release 22.214.171.124
DDdfc1 Available Data Domain DDdfc Release 126.96.36.199
this command will only revert with this output when you have the right DFC driver in AIX host as well. Read this KB article this should help you as well: https://support.emc.com/kb/464964
let me know if this works and you are able to see devices on AIX server.
