Data Protector Express recognizes any installed device that is part of the Data Protector Express
management domain and displays them on the Devices view. You can use the Devices view to perform
operations on any physical or virtual device.
Selecting Devices in Jobs
The Device page of a job’s properties lets you select the devices that will be used. You may select as many
devices as you wish for use in a job and Data Protector Express will use the devices as efficiently as it can.
You can view the available devices by either a Device view or by Network view by selecting the
appropriate tab.
The Device view allows you to locate devices according to their class — for example, tape drives. Since
Data Protector Express can read and write CDs and DVDs (optical media) a large domain may have
dozens of devices, many of which are optical devices. This view make it simple to locate the tape drives
or libraries in your network. Each class of device is represented as a node at the top of a tree hierarchy.
By checking the box next to a class of device you are telling Data Protector Expressto use any device
of that class it can find available when the job runs. This is a powerful concept because it allows you
to add additional devices to your network and to your jobs without having to reconfigure your jobs. If
you expand the class by clicking the + next to the class name you will see the names of each device
of that class. Expanding the name will show you which machine the device is attached to. Selecting a
specific device will ensure that only that device will be used in the job.
The Network view presents the same map of your devices but from a different perspective. At the top of
the hierarchy is the Network. Next to each element in this list is a set of checkboxes representing the
supported classes of devices. Selecting the Tape Devices box next to the Network configure the job to
use all tape drives in the network at the time the job runs. Under the Network you will see machines.
Selecting a class of devices next to a machine will limit the job to use only that class of device on that
machine. Finally, when the machine is expanded, all connected devices are displayed. There will be
a checkbox in the column appropriate for the class of device. Checking that box will select just that
device for use with the job.
NOTE:
New devices added to the network after a job has started running will not be available to the job until
the next run.
