Symptoms

Occasionally multipath configuration for Sun StorEdge[TM] 3510 (SE3510) with a dual-controller configuration does not work as expected when a single controller failure has taken place.

It is expected that a dual-controller configuration should exhibit controller redundancy during a controller failure. There should not be any disruption to host I/O when dual-path host connections to different RAID I/O module(s) are set up and multipathing has been configured.
