An UNKNOWN_PROTOCOL error may be returned when attempting to create Placeholder Files on a VNX target
During File System Archiving (FSA) placeholder creation the UNKNOWN_PROTOCOL error is returned when using an HTTPS secondary connection on the VNX.
The following error will be seen in the FSA task report file when Reports are set to Full on the archiving task properties.
*** Error *** - Error making file: \\?\UNC\vnxserver.domain.com\share\folder\filename.doc a placeholder file. UNKNOWN_PROTOCOL
This issue affects Enterprise Vault version 12.3.0 and higher. It is caused by an issue resolving the HTTPS secondary connection path on the VNX.
Archiving of files from the file server is not affected by this issue. If possible, an HTTP secondary connection can be used as a workaround to allow for placeholder files to be created properly.
