Bobby,

I'm running clustered master servers just as you describe, and according 
to our Symantec rep, you do not need SSO licenses for your clustered 
master servers.  However, if those same drives are shared with other 
media servers, then the answer becomes "yes, you do need SSO licenses".

Clustered NBU is not supported in an active/active config, so the drives 
are used on only one of the nodes in the cluster at any one time, so the 
drives really aren't being "shared" between the cluster nodes.  This 
also means that you do not need separate NBU licenses for each node, 
since the license "floats" to whichever node has the nbu_server service 
group.

I just confirmed this last week with our rep as we had someone here who 
wanted to set up a high availability media server.

The Veritas Cluster Server (Storage Foundation HA) agents you need for 
NetBackup are included with NetBackup.  Look at the HA Guide for 
details.  The files are in /usr/openv/netbackup/bin/cluster
