In layman's terms, when you plug a new device into an arbitrated FC loop, then the loop needs to re-initialize itself. All traffic stops. This might take one second, it could take 30 seconds. Depends on a lot of things. When a disk drive fails in a RAID subsystem, then the backend drives are almost always on an arbitrated loop, so many different hardware failures, replacing controllers, or adding new drives can suspend data flow. There are, of course ways to prevent this, but they all require additional hardware. A LIP is what this Loop Initialization process is called.
