LIP does interrupt the communication for a while, but ideally everything
would be retried on block devices at least. I don't think you need to
generate LIP in some instances (depends on how you added your LUN, E.g.
if you added new FC disk to FC Fabric switch, the Fabic would generate
an event, RSCN, without interrupting anything).
I don't know SAS world equivalents...
