In a dual-path configuration two HBAs, as a target, I would like to make one
of the paths as "unavailable", so the host will failover quickly to the
second standby HBA. As a target, I could simply drop the I/Os, but I'm
looking for a faster failover. Is there a standard SCSI event that the
target can send to force the HBA to shut down one of the HBAs and use the
other path? Any help would be greatly appreciated.
