The filter rules may be set for the whole domain and will be applied automatically to all tasks. Or,
they may be set and applied at job level. Any filter rules applied at job level overwrite the default
domain settings.

Initialization Process

The traditional loader inventory mechanism is accomplished by running an identify job on all the slots
in a library. This complete inventory can take a very long time, so Data Protector Express uses a "light
inventory" process, which is known as an initialization process. This initialization process consists of ...
• Checking that the loader is ready for use. If the magazine door is open, this step will fail, and
initialization will fail as a result.
• Querying the number of physical storage, import/export and device elements that the library
contains. (These elements will be displayed in the Tape Library view.)
• Binding the loader to its physical devices. This ensures that the devices are associated with the
library in the Data Protector Express catalog.
• Updating the status for each element in the loader. Barcodes are read at this time, and are
associated with each element regardless of status (i.e. both Invalid and Valid elements get a
barcode shown in the loader status pane).
Initialization occurs when the library driver starts (at service startup or when the driver is manually
started), when the user selects the Initialize command on the load object in the user interface or when
Data Protector Express detects that a user has changed the state of the loader (either by opening the
front door or by using the front panel).
During initialization, the library will attempt to perform barcode based identification of media. If a match
is found, the loader will set that element's status to Probably Valid. This means that if a user is using
barcodes with their tape library, they will almost never need to run an identification job.
When the job loads the tape it makes sure that the tape is really what the catalog says it is and, if
necessary, updates the catalog to indicate what is really there. If the tape is, in fact, not usable because
of the supplied media rules, the tape is re-stowed and another media is tried.
Barcodes and the Identify Job
An Identify job will always physically mount media, and reassociate media to barcodes. This provides a
mechanism for users to update barcodes on their media, should they ever need to. It also handles the
case where barcodes are added to media after they have been used without barcodes.

Media Management

There are no specific media tasks that must be carried out before you run the first backup job. As long as
you have loaded valid media, Data Protector Express will automatically use it.
NOTE:
Media is invalid if it has been used by another backup product, is dirty or has been corrupted, or simply
has not been identified.
Similarly, if you are restoring data from media that is already within the Data Protector Express catalog,
there are no media management tasks. However, if you are restoring media from a different domain, you
must first import it so that Data Protector Express can add the media to the database and associate all
data objects on the tape with that media.
For a detailed description of all media management jobs, please refer to the relevant section of this guide.
This section describes the following media management jobs that are appropriate to tape libraries:
• Import Media: used to add media to the catalog (this job applies to all devices, not just tape
libraries).
