Re: SAN switch portshow
it seems to be the faulty SFP on the switch port or the switch mainboard port itself. You are probably using the wwn-based zoning or no zoning at all. It is good to run the porterrshow to see if the CRC errors are continuously increasing or stable and if they are growing you can run the supportshow/supportsave command and send them to the vendors FTP.

Point to errors on the other side of the cable (the HBA).
