Storage monitoring IBM V7000

Storage monitoring IBM V7000

Did anyone succeeded with monitoring IBM V7000 storage?
I have added SMI credential with cluster IP. Then I am trying to "Add storage device" in "Discovery" menu with node IP address, however - when I click "Test connection" I always get an error: "Test connection is failed". Is there a log locally where I can see what message storage has passed to the OpM?
Maybe worth to mention, I am using OpM 12.3.230
