There are a few tests for the VMAX driver that are causing lots of
unit test failures on various patches. I think the reason is several
tests are using the config file with the same name which is created
during setup and deleted at cleanup. When concurrency is > 1, one test
could have deleted the file while another test is trying to read from
it. So the unit tests need to be re-designed to isolate the impact on
each other. This will be worked on. For the short term, I want to
remove the bad tests to reduce the number of unit test failures on
other patches.
