When attempting to update the configuration on the EMC Celerra tab of the file File Server Properties the following is displayed. Unable to send requests to the Celerra file server server_name.

A Dtrace of the EVFileSvrArcMngr process will display the following-
(EVFileSvrArcMngr) <21640> EV-L {PlaceHolder.GetFIPSRegistryConfig} FIPS setting: 1
(EVFileSvrArcMngr) <21640> EV-L {PlaceHolder.CreateServerUri} https://UnityServer.Domain.com:5080/dhsm
.
.
(EVFileSvrArcMngr) <21640> EV-L {PlaceHolder.GetWebResponseStream} HTTP Request:
(EVFileSvrArcMngr) <21640> EV-L {FileServerArchiveManager.KVS.EnterpriseVault.FileServerArchive.IAdminClientManagement.ValidateDataMoverUserAccount} Web Exception occured while communicating with https://UnityServer.Domain.com:5080/dhsm Error message: The underlying connection was closed: An unexpected error occurred on a send.
This looks to be an issue with FIPS being configured on the EV server. When this is configured the process will default to an HTTPS connection. HTTPS connections are not currently supported with Unity file servers.
If possible disable FIPS on the EV server to allow for the HTTP connection. If FIPS cannot be disabled the Unity server will not be able to support placeholder creation and Internet shortcuts will have to be configured.
This update should allow for the Unity configuration to be saved and placeholder creation to occur properly.
