Is it possible to disable a servers vNIC or vHBA? I was unable to find an option to do this via the GUI, maybe CLI? The reason is I would like to ensure the failover mechanisms and paths are correctly configured...
There is no option to disable the vNIC or the vHBA in the GUI or the CLI.
However you can try the following:
Try shutting the ports on the uplink switches for both the ethernet and fc. With the concept of the interfaces pinned to the uplink interfaces in the end host mode the vNIC and vHBA will go down and trigger the failover.
Note: Shutting the uplinks will bring down all the vNIC and vHBA for the fabric, hence you may want to plan the testing accordingly.
Just to add to what Abi said. Testing failover can be tricky. Though adaptors can't be disabled through UCSM you can reset the DCE Interface. This will disrupt any & all vNICs/vHBAs bound to that fabric for that blade. By shuffling the uplink ports you're going to risk disrupting ALL server traffic and assuming there's always at least one path still available traffic will just get re-pinned to the remaining uplinks. The host may/may not activate failover in that regard depending on the timeout settings of the host.
