2. The MSM starts the Media Agents (MAs) on the system that has devices used
for the media management session.
3. Media Agents perform the requested operation and send generated messages
to the Data Protector user interface, where you can track the progress. The session
is also stored in the IDB.
4. When the session is complete, the MSM closes the session.
How many sessions can run?
A number of media management sessions can run in the cell at the same time if they
do not use the same resources, such as devices or media.
