Log message:
support "failover" style access to volumes, ie, only use one active
path when talking to an array until it goes away, then you fail
over to the next active path.
im using this to talk to ses(4) in my dell, and allows us to support
arrays that have multiple controllers but have no way of reporting
which one is active. using the MRU semantic means we can talk to
them without them flipping the active role between its controllers
all the time. claudios transtec iscsi box is like this.
