I am very new to storage but we are having trouble with performance on our SAN. While troubleshooting I found that one of our switches in the fabric (1 HP C7000 with 2 flexbric interfaces connected to 2 SAN Switches connected to 2 HP 3Par SAN nodes) had pretty much no traffic.
I was wondering if that kind of situation was "expected" (maybe it's using 1 switch as primary and the second as failover) or if it could indicate some problem.
When running a single "porterrshow" on the Brocades, or "portperfshow", I can see a lot of stats on Fabric_A but almost nothing on Fabric_B.
Is it normal to have traffic on just one interface, and not load balanced across interfaces?
Let me know if you need any details on the setup.
