●

Data Mover or NAS server restarts — The list of unscanned files is stored in a directory reserved by the panic handler

software. When the Data Mover or NAS server restarts, the virus checker reads the list of unscanned files, and then scans

the files.

●

Virus checking is stopped or a file system is unmounted — The list of unscanned files is stored in a special file on the file

system. When the virus checker is restarted or the file system is remounted, the virus checker reads the unscanned list and

scans the files.

The list of unscanned files is stored in the /.etc/viruschecker.audit file on each Data Mover or NAS server.

On a VNX, use this command to manually update this file.

1.

Store the list of unscanned files by using this command syntax:

$ server_viruschk

<movername>

-audit

where:

<movername>

= name of the Data Mover

For Unity systems, use Unisphere to manually update configuration information.

1.

Under

.

2.

Select the relevant NAS Server, and then select the

Edit

icon.

3.

On the

Security

tab, select

.

4.

Select

Retrieve Current Configuration

.

5.

Edit the configuration file, and then save the changes.

6.

Select

Upload new configuration

to upload the updated configuration file.

CAVA sizing tool

The CAVA sizing tool runs on Windows-based systems. The tool assists the system administrator in determining how many AV

engines are necessary to provide adequate AV scanning across VNX and Unity systems.

The tool gathers information based on the specified AV machines queried, and returns statistics on each AV machine.

When you install CAVA on the AV machines, the CAVA sizing tool, cavamon.exe, is also installed. In addition, you can use the VB

script, cavamon.vbs, to monitor the AV machines. However, cavamon.vbs does not perform sizing.

The heuristic in the sizing tool is set to size the CAVA environment for an average 60 percent saturation level (or workload

level) in all AV machines in the environment. Users wanting to use their own heuristic for sizing can use the cavamon.vbs script

for gathering CAVA statistics. These statistics can then be used as input to custom algorithms.

Configure the sizing tool

describes configuration procedures.

CAVA sizing tool configuration overview

Configure one or more AV machines in the network as the monitoring CAVA sizing tool server—this is the server that you use

can to monitor and size all other AV machines. The monitoring system, and all AV machines that you want to monitor, must be

running the WMI subsystem. WMI is built into Windows systems.

NOTE:

The CAVA sizing tool must run on an AV machine—you cannot run the sizing tool from any Windows machine in the

domain.

The CAVA sizing tool must be enabled on the AV machines that you monitor. However, you do not have to configure the sizing

tool on these machines. If you want the ability to monitor CAVA from multiple machines in the network, you can enable and

configure the CAVA sizing tool on multiple machines.

The monitoring sizing tool server:

●

Monitors all other Windows Servers running CAVA

●

Monitors and gathers statistics on the AV engines

●

Gathers and lists workload information for each individual AV engine

●

Provides recommendations on how many AV engines are required to provide optimal antivirus protection
