Currently, there is no resolution or workaround.
Currently, VMware does not recommend running NX-OS 7.3 on Cisco MDS switches until Cisco has provided a code fix. This is due to the fact that VMware cannot guarantee a successful path failover in the event of storage array controller maintenance or upgrades that require rebooting the controller.
