Interesting - first time I'm seeing 0/0/0. The 1st is usually 0x2 (see [1]), and then the rest [2], [3] make sense.

A google search found another user with Clarion with the exact same error[4], so I'm leaning toward misconfiguration of multipathing/clarion here.

Is your multipathing configuration working well for you?

Are you sure it's a EL7 configuration? For example, I believe you should have rr_min_io_rq and not rr_min_io .
