Is there a way to test vNIC or hba failover on an individual blade. I don't want to have to turn a fabric interconnect off to validate that I have setup a vNIC or hba appropriately on a single blade so is there anyway from the Fabric Interconnect cli to disable a vNIC / hba or force it to failover to the other fabric?
Unfortunatley not, would be nice to be able to do a "Shut" on a veth in NXOS mode but you can't (not yet anyway.)
The best way I have found to test blade failover with MINIMAL disruption is to pull the FEX - FI link out, that that blade Pins to. THIS CAN EFFECT other blades depending on your setup.
I.e. if you only have a single FEX link obviously all your blades will be using it.
Best scenario is to use 4 FEX links (If using Gen 1 kit, with discrete pinning) then if you have a full chassis of half width blades you will have 2 servers pinned to each uplink. i.e. 1/5 to link 1, 2/6 to Link 2, 3/7 to link 3 and Blades 4/8 to link 4.
So if you pull FEX link one on FEX A out in the above scenario, all vNICS mapped to Fabric A will failover (if configured to do so) on blades 1 and 5.
Not ideal but better and much quicker than failing a whole FI as you were thinking about.
Obviously the above will not work if you have port-channelled the FEX - FI links.
You can test fibre channel failures by putting one of the vHBA's into another VSAN. This will break the zoning for that vHBA. You can just create a dummy VSAN if you don't have one to put it into. This will test your multipathing to the target. vfc's will not failover like a veth will on loss of connection or FI.
There are requests to be able to shut/no-shut a vif, but, nothing so far.
