Hi, i do have an active-passive Storage where the LUN could be used by both Controllers but one is bloody slow. I tried all /sbin/mpath_prio_* ways do determin which is the "active" one but none of them worked. Is there a way to set this manually? Is there a different way to determin which is which rather than using the existing Commands?
