I add that for NetApp aix binaries to be compatible with every AIX version supported on IMT, they must be compiled on the lowest level of AIX (5.3) ou in 5.3 compatibility mode.
AIX supports ascending binary compatibility, not the contrary. A binary compiled on an old AIX will execute on all higer versions of AIX. A binary compiled on AIX 7.1 won't execute properly on AIX 5.3. This could be the problem here ?
Not sure about this, we dont test accessing through CIFS so it isn't something we would officially support. If this is an issue it isn't something we can do anything about either. The SC code is platform indepedent meaning exact same source code in every binary, so this would be a compiler issue if it is issue on SC side.
This sounds like a CIFS or OS issue however, our binaries are compiled for AIX and will run on AIX for systems in the IMT.
Why do you want to access binary's from AIX through CIFS? What problem are you solving by storing binarys on CIFS share?
You can run an scServer on windows box and an scAgent on AIX, that is a much better solution if you are trying to solve centralization problem.
