About protecting against SAN client failures

The SAN client, like the SAN media server, does not send backup traffic over the network to the media server. However unlike SAN media servers, which send backup data directly to the storage devices, SAN clients send backup data over a SAN connection to a remote media server.

SAN clients are often used to protect clustered applications. To protect NetBackup against SAN client failures when used in this way, configure the SAN client as application clusters in EMM. This configuration also ensures that the media server controlling the backup always opens a fiber transport connection to the active node of the cluster when a backup is initiated.
