We use Macfee for Netapp v7.1 currently.  We have assigned a VM box with a 1gb connection to each filer.  Each filer also has secondary connections configured over normal Production interfaces to non-primary servers.  This mesh ensures no disruptions if the primary drops its connection.  We have mandatory_scan=yes.  

Some issues we ran into:

1.  7.1 has no upgrade path that I know of.  Our server/desktop environment is supported via EPO, and in the latest release (4.0) there is no support for 7.1 Netapp agent.  This means we will need to manually manage the AV settings outside of the normal process
2.  Bug with resetting the LAD date on Excel files.  Fixed with - priv set diag; setflag smb_ignore_vscan_set_mtime 1; priv set
3.  Bug with resetting the LAD on manual scans.  Fixed with patch from Macfee (can't remember the #)
4.  Random service crashes/stops/hangs on the AV servers.  Can't determine an exact cause, but each filer will lose connection.  Happens randomly about twice a week across 16 filers.  Having secondary_scanners enabled helps with the problem.

Regards,
Scott

Re: CIFS virus scan




I'm looking to deploy some windows homdir filers with virus scan
protection.  I'm curious what people think of McAfee's product.

If the script detects that one of the virus scanners has disconnected, the script issues a "vscan off" command to the filer. Usually a reboot of the scanner box that is having problems fixes this. I have found when this starts happening, I need to go look for a driver update on CA's site and get it installed. When the newer driver is installed, the problem goes away for several months.

The weird thing is that it only complains about this once in a while. When it dos complain, it complains a lot. The error message is also odd too something like "File Infected with <space character> detected".
