Media server disk discovery
This Discovery process probes all the media servers associated with the management server to gather disk-based information such as capacity and free space on the media server file systems. This information is then displayed in the Disk Usage and Performance report. If the Media Server Disk Discovery process is not enabled, disk-based information will show as Unknown in reports. If you have several primary servers in your environment, and they have media servers and disk storage units attached to them, you must enable the Media Server Disk Discovery module on each of the primary servers.
