We have McAfee 7.1 running both in VMs and a physical machine with no apparent difference. Both show plenty of 0x05 errors, mostly with Excel files. Case closed without solution, for Netapp and McAfee.

For people who are still in the design phase of their AV solution and are worried about performance or if you are having roaming profiles. Avoid using of vscan servers in VM boxes, this is mostly ending in much worse performance then a physical machine.
There is a new version of McAfee upcoming (8.7 afaik) that will be working with epo 4.x.

Andy

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.

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.

We currently use etrust antivirus 8.1 from Computer Associates. Using two HP DL 380's as virus scanners (redundancy and load balancing). The product works pretty good but does tend to have some odd issues.
Sometimes complaining that it cannot update the virus definitions. - This situation caused a denial of service to CIFS files on the filer a couple of times. (even with "vscan options mandatory_scan = off") - This DOS happened with version 7. - Have upgraded to version 8, the update issue just re-occurred yesterday. - Mitigation, we have a *NIX script that monitors the filer's syslog. 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.
Configuration options are limited. - cannot exclude files that are greater than $Size - Old version had problems scanning big files. 100 meg or so. PPT files were especially bad. - New version has similar issues. Have had to exclude .zip .tar .rar as well as .ppt from scanning. Run Norton corporate AV on the desktops which limits our exposure slightly. - Alerting is difficult to configure - product is very noisy by default.
Product also complains about being unable to scan files when it's trying to scan things like Microsoft Word droppings - those ~file.tmp files that office creates. 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".
Over all, the product works okay. If I have my say, I would prefer using something else. Our organization bought it because it was cheap. You get what you pay for.
PS. Current vscan options vscan options timeout: 10 sec vscan options abort_timeout: 10000 sec vscan options mandatory_scan off vscan options client_msgbox off

Hi guys,
We have been using the Symantec scan engine for NetApp for several years now, but we've met more and more problems as of late. As the next license upgrade will be due in a couple of months, that might be a good opportunity to replace it by a different brand altogether.
Hence my question to the list: Which antivirus product do you use and how satisfied are you with it?
Kind regards, Mark Neis
