FILESTREAM File I/O access is enabled, but no listener for the availability group is created. A FILESTREAM PathName will be unable to refer to a virtual network name (VNN) and, instead, will need to refer to a physical Windows Server Failover Clustering (WSFC) node. This might limit the usability of FILESTEAM File I/0 access after an availability group failover. Therefore, we recommend that you create a listener for each availability group. For information about how to create an availability group listener, see SQL Server Books Online.
