If you use the BRMS Network feature and use a shared media inventory among systems in the network, BRMS may need to access another system in the network during the backup to take ownership of a scratch volume owned by another system. This usually occurs when all volumes owned by the current system have been used. If this situation occurs while you are in restricted state the backup will end with an exception due to volumes not being available. You can configure BRMS to start up a TCP/IP interface which it can use to communicate with other systems in the network while in restricted state.
