Target client nodes own data and agent nodes act on behalf of the target nodes. When granted proxy node authority to a target node, an agent node can perform backup and restore operations for the target node. Data that the agent node stores on behalf of the target node is stored under the target node's name in server storage.
Agent nodes are considered traditional nodes in that there is usually a one-to-one relationship between a traditional node and a physical server. A target node can be a logical entity, meaning no physical server corresponds to the node. Or, it can be a predefined node which corresponds to a physical server.
By using the GRANT PROXYNODE command, you can grant proxy node authority to all nodes sharing data in the cluster environment to access the target node on the Tivoli® Storage Manager server. QUERY PROXYNODE displays the nodes to which a proxy node relationship was authorized. See the Administrator's Reference for more information about these commands.
Proxy node relationships will not be imported by default; however, the associations can be preserved by specifying the PROXYNODEASSOC option on the IMPORT NODE and IMPORT SERVER commands. Exporting to sequential media maintains proxy node relationships, but exporting to a server requires specifying the PROXYNODEASSOC option on EXPORT NODE and EXPORT SERVER.
