Scott,
Nice to meet you. You seem pretty knowledgeable with how vscan operates.
I put something to you.... This, http://media.netapp.com/documents/tr-3107.pdf, and my interest is squarely on Figure 1.

And, Step 2.
So, I have an issue with a filer that when you issue the command 'vscan', and it shows you, at the bottom of the output, 'Number of files scanned', 'Number of scan failures', 'Number of throttled requests', the Number of files scanned does not increment.
Who's jurisdiction is it to appropriately increment this counter.
The filer, alone ? I think yes, if vscan is enabled. Or does it need to be 'registered'/'associated' with a relevant AV vendor's scanning server/solution ? And it only increments if this successful registration is made ?
