If you are planning to implement SAN Media Server, this chapter is really relevant for you
Enhanced media server configuration
This configuration is supported for Veritas Cluster Server (VCS), Microsoft Cluster Server (MSCS), Sun Cluster, Service Guard, and HACMP.
In a typical NetBackup environment, the storage unit is associated with a NetBackup entity, such as the master server or media server. In the configuration that is described in this chapter, however, a storage unit is associated with the virtual name of the application in the cluster environment. The storage unit for that application is not associated with any specific node in the cluster and can failover to any node in the cluster. This guarantees that the storage unit follows along with the application, wherever the application is running in the cluster. The NetBackup master server uses the virtual name of the application as the media server name when it backs up the clustered application.
