Comment 2 Eric Harney 2018-01-29 15:38:36 UTC

Hi,

It looks like the Unity driver is skipping the test_force_detach_volume test in upstream Unity Cinder driver CI.  As this is a normal tempest volume test, it should be enabled and functioning for this driver.

Required changes for the driver to pass this test should be made upstream, and then we can consider backporting those changes to OSP12.

Thanks,
Eric
