Is this connected to some SAN storage? It looks like you have had a temporary outage on your SAN which has caused the host bus adapter to reset. You shouldn't have any serious side effects as long as all of the SCSI retries succeeded, i.e. there were no 'fatal' errors in the log.

I wouldn't worry too much if this is a once off, but if it happens regularly you should start looking for some failing hardware (dodgy GBIC or cables?) in your SAN.
