Understanding virus scanning for a vFiler unit

Who can configure virus scanning

You (the hosting storage system administrator) can specify how virus scanning works on files owned by the hosting storage system and files owned by vFiler units. vFiler unit administrators, however, cannot configure virus scanning for vFiler units.

Storage Systems with which virus scanners can be registered

Virus scanners can be registered with the hosting storage system or any vFiler unit. You can determine whether files on a vFiler unit are scanned by virus scanners registered with the hosting storage system or the vFiler unit.

Note
A virus scanner local to a vFiler unit always takes precedence over the virus scanner registered with the hosting storage system. If a virus scanner is registered with a vFiler unit and that scanner is functional, the files on the vFiler unit will be scanned by this scanner. If this scanner becomes unavailable, and the vscan options use_host_scanners command is set to On and a scanner is registered with the hosting storage system, the files on the vFiler unit will be scanned by the hosting storage system's virus scanner until the scanner local to the vFiler unit becomes available.

Virus scanning for vFiler0

Because vFiler0 is the hosting storage system, files on vFiler0 can be scanned only by virus scanners registered with the hosting storage system.

Requirements for virus scanning for a vFiler unit other than vFiler0

These requirements must be met before you can scan files on a vFiler unit other than vFiler0:

Virus scanning must be enabled for each vFiler unit.
A virus scanner must be available for the vFiler unit because one of the following requirements is met:
- A virus scanner must be registered with the vFiler unit.
- A virus scanner must be registered with the hosting storage system and the vFiler unit must be allowed to use it.

Effect of virus scanner availability on CIFS access

Even if virus scanning is enabled and the mandatory_scan option for the vscan command is set to On, CIFS clients of the vFiler unit are not allowed to open any files on the vFiler unit if no virus scanner is available.
