There are two steps to adding an IP to a vfiler and another for having it remain after a reboot, the first is to make the IP available to the vfiler, the second is to make it active on the system, but this does not make persistent across reboots. The ifconfig line for the alias must be added to /etc/rc for persistence.
You run ifconfig <interface> alias <ip_address>, but that does not attach it to the vfiler.
You run vfiler add <vfiler> -i <ip_address> but it does not add it to the /etc/rc for persistence across reboots
By running both commands, the vfiler can use the IP immediately and then once the required alias entry is added to /etc/rc it will remain when the controller is rebooted.
