Hello Experts,

I have a simple query.

Let say i am having two computer which are connected on fiber channel
switch. How can i check the connectivity between these two computer. For
eg if the same two computer are connected on ethernet i can use tcp/ip
protocol and i can ping command to test the connectivity similarly how
can i check the connectivity between two computers when connected using
fiber channel.

Assuming the fiber channel switch's mapping is flat (every port can see
every other port), you could query the HBA on one server to see if it
sees the WWNs of the other server. You'd probably need one of the tools
that come with your HBAs to do this (e.g. "scli" for QLogic cards).
