I have installed McAfee VirusScan 7.1 onto a scanning server. It connects to the filer successfully and on the filer it is registed as a Vscan Server. However, if I check the statistics of the AV scanners in the NetApp Appliance AV console - it is 0. If I turn off the AV Scanning server - I am still allowed to write files, even though the mandatory_scan option is set to on on the filer. The On Access scan properties are to read from disk, write to disk and scan network drives.
