The masks= is set to *.* and the antivirus engine is configured to scan all files. a. If masks=*.*, renames will not trigger scanning. If the masks option does not equal *.* (that is, *.exe, *.bat), then a trigger will occur. NOTE: When virus checking is enabled, two clients cannot concurrently write to the same file. The first client that requests the file opens the file for write access. The second client must wait until the file is closed by the first client, and, if the first client modified the file, until the file is checked by the AV machines. Configuring viruschecker.conf The viruschecker.conf file defines virus-checking parameters for each VNX Data Mover or Unity NAS server in the domain. For CAVA to work properly, some parameters, such as the addr parameter, must be configured. Other parameters are optional and you can configure them if you want to control the scope and style of the virus scanning. This guide describes only the command-line procedures. In a Windows Server environment, you can also use the Dell Unity/VNX/VNXe NAS Management snap-in to modify the antivirus agent parameters on the Data Mover or NAS Server. EMC Unity/VNX/VNXe NAS Management is installed as an MMC snap-in to Unisphere. Installing Management Applications on VNX for File provides instructions on installing the snap-in. Create and edit viruschecker.conf For Unity systems, you can either retrieve the configuration file in Unisphere and edit it, or you can upload a configuration file that you create offline. The antivirus configuration is found in Unisphere at Storage > File > NAS Servers > Properties > Security > Antivirus. For VNX systems, ensure that the viruschecker.conf file resides in the /.etc directory on the Data Mover before editing. You can either create a new viruschecker.conf file or retrieve the existing viruschecker.conf file and edit the contents: ● If the viruschecker.conf file exists in the /.etc directory, type the following command to retrieve this file for editing: $ server_file -get viruschecker.conf viruschecker.conf ● If the viruschecker.conf file does not exist in the /.etc directory, copy the template viruschecker.conf file from the /nas/sys directory on the Control Station to another directory, such as /nas/site for editing with a text editor. 64 Unity and VNX CAVA Information
