If I remember correctly the vHBA will never go down when all FCuplinks go down. For ethernet you can configure this behaviour but not for FC. UCS relies on the HA features (multipathing) within FC to detect an uplink failure from the FI towards the SAN. It might also be unwanted behaviour as FC uplinks are not always required for example when the FI is in FC switch mode and the storage array is connected directly to the FI.
I did some test once and when you remove one uplink it does a new flogi on the remaining uplink of that FI if all uplinks are gone the path goes down.
create a test / dummy VSAN, something which does not carry your production data and is not configure on the uplinks. Assign the VSAN to the vhba and that will take the vhba down without having to shut your fc uplinks.
