ssacli parsing failure with problems

[Marc Hagen]

I've some G10 servers that failed parsing with ssacli.

While its not throwing errors, it is saying there are 3 controllers in the system.
But there is only one.

Python output for getting controllers
```

  'module is not attached. Please re-attach the': None,
