What NICs in your chassis? As I mentioned before that "DCB and PFC PAUSE typically used and required by fcoe", but you are using PAUSE and switch cannot be eliminated as you mentioned before, these could affect more to FCoE than other protocols, so can you ensure IO errors are not due to frames losses w/o DCB/PFC in your setup ? While possibly abort issues at target with zero timeout values but you could avoid them completely by increasing scsi timeout and disabling REC as discussed before. Please use inline response and avoid top posts.
