What is upstream swith and downstream switch

Yes, they need to be in the same VSAN for them to login to Fabric and see each other.You also need to configure Zone and activate the zone-set for the storage and server to talk to each other. If they are in different VSAN's, you have to use IVR and IVR zones for them to see each other.

Re: What is upstream swith and downstream switch

Thanks for the link.

I guess, I need to ask more particular questions. The following is what I excerpted from page 5-3 on this document: http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/troubleshooting/guide/n5K_ts_sans.pdf

"A server port connected to the NPV edge switch does not come online, and the show interface command

indicates a status of NPV upstream port not available.

Possible Cause:

The upstream NP_Port(s) and the downstream server F_Port(s) on the NPV edge switch may not be in

the same VSAN. "

Just wanted to confirm with understand the issue. To resolve the problem, in the case as following, fc2/2 on the upstream switch should be in the same VSAN as the port fc1/5 on the downstream switch? Am I understanding it right?

fc2/2, NP_Port, To a storage
