About the MSDP host configuration file
Each NetBackup host that is used for deduplication has a configuration file; the file name matches the name of the storage server, as follows:
storage_server_name.cfg
The storage_server_name is the fully qualified domain name if that was used to configure the storage server. For example, if the storage server name is DedupeServer.example.com, the configuration file name is DedupeServer.example.com.cfg.
The following is the location of the file:
Windows: install_path\Veritas\NetBackup\bin\ost-plugins
UNIX: /usr/openv/lib/ost-plugins
