Actually, for this exact case, there's a feature propagating through the transport classes called the dev loss timer. It's job, for pluggable transports like FC, is to allow the user time to unplug and replug cables before the system declares the device lost and starts erroring requests (which is what causes the fs to go read only). Since the original reporter seemed to be using fibre, it sounds like this would suit. Beware: the dev loss timer shouldn't be much longer than the SCSI command timeout (say ~30s) or nasty things may happen.
