Wrong port type on a Silkworm 3250

Extracting some info available via SNMP from our Silkworm 3250 8 ports fabric switch, we found that a port (number 5) linked to a QLogic QLA231x/2340 (rev 02) hba installed on a sun V40z shows a very high (around 250k errors/s) sustained errors rate (the oid polled is connUnitPortStatCountError), while all the other 4 ports seems to behave kindly.--

Check the configuration on the Qlogic hba. I'm sure it's configured in arbitrated loop mode rather than fabric mode. The switch will report the connection type received from the target. (hba)

I think it's an HBA misconfiguration issue. You should be able to disable loop in your HBA config file so that it only negotiates Fabric.Let us know if this works.

You should check the driver conf file to make sure that you are using Fabric mode.Also portcfglport locks the port to only do loop it will not try fabric login with the device. The command to skip loop init on a port is portcfggport, but if the device is configured only for loop this not help, so I would start at the device configuration and if it is ok then lock the port as a g-port
