As per FC-LS Rev 1.62 table 46, response codes are handled as follows: 1. If the Req executed is true, PRLI is accepted. 2. If Req executed is not set, if resp code is 5, PRLI is not retried and port is logged out. 3. If resp code is anything apart from 1 or 5, PRLI is retired upto max retry count.
