Error description
If commands are timing out to a Fibre Channel Storage device, then Fibre Channel drivers may use Target Reset to bring back the device. Many newer storage devices support LUN Reset, which would only affect that one LUN instead all LUN's under the target. Using Target Reset may result in more errors seen on FC Fabric after command time outs.
