The aim is to exclude certain file types from scanning by Symantec Scan Engine.
The NetApp Filer submits files to Symantec Scan Engine (SSE) for scanning based on the file extension of the top-level file. Files are scanned when they are accessed from storage (read), renamed (write) and when submitted for storage, if modified (write).
The extensions that are configured on the NetApp Filer have preference over the file types and the extensions configured on SSE. For example, if .doc is included in the extensions include list for the NetApp Filer but is excluded on Symantec Scan Engine, .doc files are still scanned.
A default list of extensions to be submitted for virus scanning is included with the NetApp Filer. To modify the extensions include list, at the command line interface, use the “vscan extensions include add” command to add additional extensions and the “vscan extensions include remove” command to remove extensions from the list.
