Multiple interfaces are assigned IP addresses on the Vscan server side. Interface 1 192.168.1.200 > For vscan service Multiple data LIF is configured on the ONTAP side Only one Vscan server-side IP is added to the "scanner-pool" on the ONTAP side. It's meaning the other one of the Vscan server's IP(172.16.67.200) is not allowed to initiates the Vscan connection.
