6.3 HP StoreAll Storage File System User Guide (TA768-96093, June 2013)

Recommendations for Antivirus scans:
• Run Antivirus scans when the system is not being heavily used.
• Configure your Antivirus scans so that a huge number of files in a subtree are not assigned
to an Antivirus scan.
• Do not run Antivirus scans on many file systems at the same time as there is a resource limitation
on the AV daemon.
Keep in mind the following in regards to Antivirus scans:
• Antivirus scan task let you specify a file system or directory path under which all the files will
be subjected to antivirus scans, which is different from on-access scanning, where a scan is
triggered, when the file is accessed by an application, typically during a open/read operation.
On-access scanning is done automatically by the kernel. The AV feature defines a mechanism,
which lets you run or schedule periodic Antivirus scans on an entire file system or directory
at any time.
• Antivirus scans are independent of on-access scanning, and they can be run in parallel.
• Antivirus scans are similar to on-access scans in that they continue to honor exclusion rules
defined by you.
When you set an Antivirus scan, you are asked to enter a value for the duration scan. The maximum
duration scan that can be provided is 168 hours (7 days). If a duration time is not provided for
the scan, all files in the given path are scanned without any timeout.
You can plan the scheduling option so that Antivirus scans run on multiple directories in serial. For
example, assume you have five directories on which you want to run Antivirus scans in a particular
priority order. You could schedule an Antivirus scan to run on the first directory for 2 hours maximum
(value in the Duration of Scans text box) at a set time. Then, schedule the scan task on the next
directory after 2 hours (T+2.15 (15 minutes extra as a previous Antivirus scan needs a few minutes
for cleanup)). Do the same steps for the next three directories.
Starting or scheduling Antivirus scans
You can start Antivirus scans by using the Management Console or the CLI. Only the Management
Console provides the functionality for scheduling Antivirus scans.
Management Console
To start a scan or schedule periodic scans on the Management Console:
1. Select the file system to be scanned from the Filesystems panel.
2. Select Active Tasks > Antivirus Scan from the lower Navigator panel.
3. Click Start on the Antivirus Task Summary panel
You can also click New on the Active Tasks panel and then select Antivirus Scan as the task
type on the Starting a New Task dialog box.
4. Complete the Scan Settings tab on the New Antivirus Scan Task dialog box. Specify the
directory path to be scanned and the maximum number of hours (optional) that the scan should
run. At the end of that time, the scan is stopped and becomes an inactive task. You can view
the scan statistics of an inactive task in the Inactive Tasks panel.
5. Antivirus scans can be scheduled or started immediately. If you click OK on the Scan tab
without populating the Schedule tab, the scan starts immediately.
