We are trying to get our UCS environment setup to do SAN boot to LUNs on our NetApp storage. We have a pair of Nexus 5Ks with the Enterprise / SAN license on them and the 6-port FC module installed. What needs to be done to configure the Nexus 5000 to operate as the SAN switch between the storage target and the UCS environment?
Are you seeing the 6120 WWPNs on the N5Ks? What is the output of "show flogi database" and "show int br"
Did you map the FC ports on the 6120 to the correct VSAN?
Is npiv enabled?
