File Screening - HP StorageWorks 4000s - NAS Administration Manual

Within each policy, there are a number of configuration screens that are presented in the form
of a wizard. The wizard collects the following information to create a policy:
The notification field allows for the creation of a message to be sent to the eventlog of the
server or via Netbios as a pop up on the client machine. It should be noted that Netbios is not
supported in all customer environments and the pop up function may not be supported.The
notification includes macro functionality and variable definitions for user custom messages.
The help function (?) in the right hand corner of the UI provides an online guide to building
these macro function messages under the topic "Directory Quota Alarm Notification."
To modify any of these settings at a later time the properties button may be selected for a
particular policy or quota. In addition, to policy settings for existing shares, default policies
can be set in advance for new devices added to the system via the preferences button on the
Directory Quota Page.

File Screening

File screening allows the administrator to limit or monitor files based on extension, for
example disallow all .pst and .mp3 files. It should be noted that the filter is merely based on
extensions and not the content of the files. Hence, if a file extension is renamed away from
.mp3 for example to mpp, the filter software will allow the file to be stored. A complete online
help guide in the WebUI is provided for file screening via the ? in the right hand corner of the
UI.
File screening is established in the policy settings. Screening groups contain a collection of
authorized and un-authorized file extensions. Filters determine which folders to exclude.
Alarms, similar to the actions when a quota threshold is exceeded, can be set up when an
unauthorized file type is set up.
