Veritas NetBackup - Enable unrestricted media sharing for all media servers

This is using Veritas NetBackup 8.1.1. There are 2 Master server in veritas cluster, 4 Linux Media servers, and 2 Windows-based data movers.

Backup jobs to for both physical servers and VMs are working fine. However, backup jobs for a tape is dedicated for a selective media server. For example, if tape a4008 is used by media server nbu03, then this tape is dedicated for job from nbu03 only.

On Media host properties of Master server, I found this options - Enable unrestricted media sharing for all media servers (currently is disabled_. What would be the results with this option enabled? any side impact or other considerations?

The below is from Netbackup website

Configuring unrestricted media sharing

Unrestricted media sharing means that all NetBackup media servers and NDMP hosts in your NetBackup environment can share media for writing.

Note:

Do not use both unrestricted media sharing and media sharing server groups. If you use both, NetBackup behavior is undefined.

To configure unrestricted media sharing

In the NetBackup Administration Console, in the left pane, expand NetBackup Management > Host Properties > Master Servers.
In the right pane, double-click the master server.
Select Media
Select Enable Unrestricted Media Sharing for All Media Servers.
If you allow unrestricted allow media sharing in your NetBackup environment, you do not need to create media sharing groups.
Click OK.
