Re: Checking Fabriclog output

I have a issue ,couple of ports are flapping and able to see in fabriclog -s output.

 

So i wanted to confirm issue is there from SAN Switch port side or from served end. Hope now its clear.

Re: Checking Fabriclog output

the simple way is the command "porterrshow" port_number

 

if the port is flapping, in most case is caused by defective SFP on Switch Side, or HBA, or cable.

 

have you tried to run SAN-Health ?

Re: Checking Fabriclog output

the port show some error, but nothing dramatic.

 

I would try to replace the SFP, if the error persist the check the cable.
