That is an Old Timey Isilon OneFS release - its REST implementation was a little.... interesting.
One of the things Isilon did in those early 8.0.0.x releases was drop in some HTTP hardening stuff: I believe that some early 8.0.0.x OneFS do not have CSRF support, but then on a certain release, you must pass some CSRF hardening attributes in your requests.
CI is going to default to doing that CSRF stuff because most folks are on OneFS > 8.0.0.x
We have an "Expert" property that allows this stuff to be disabled for a given array - it may be that 8.0.0.4 needs that.
Finally, I would recommend saving the collector and letting it run - our "test" code is not necessarily identical to what we do at runtime for various reasons - we as a rule try to knock down the most common misconfiguration aspects with our test functionality, but we don't necessarily test for every possible situation - it may well be that given how old 8.0.0.x is, we are not testing properly for those non-CSRF releases that are > 5 years old
