I don't think panic should be the answer in this type of scenario, as
there is redundant path to the LUN and Hardware Raid is in place inside
SAN. From what I gather there is work being carried out to find a better
solution. What is the proposed solution or when it will be availble is
the question ?


But Roshan, if your pool is not replicated from ZFS'
point of view, then all the multipathing and raid
controller backup in the world will not make a difference.
