IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive ...

2. Register each node with the Tivoli Storage Manager server, if it does not exist.Register the common target node name to be shared by each of the agent nodesused in your shared data environment.3. Register each of the nodes in the shared data environment with the TivoliStorage Manager server. This is the agent node name that is used forauthentication purposes. Data will not be stored using the node name when theasnodename option is used.4. Grant proxy authority to all nodes in the shared environment to access thetarget node name on the Tivoli Storage Manager server, using the grantproxynode command (Tivoli Storage Manager administrator).5. Use the query proxynode administrative client command to display theauthorized user’s client nodes, granted by the grant proxynode command.Suggestions:v All agent nodes in the multiple node environment should be of the sameplatform type.v Do not use target nodes as traditional nodes, especially if you encrypt your filesbefore backing them up to the server.Restrictions enforced within a proxied session:v You cannot access another node (either from GUI drop down or use of theFromnode option).v You cannot perform NAS backup or restore.Related reference“Asnodename” on page 267Use the asnodename option to allow agent nodes to back up or restore data onbehalf of another node (the target node). This enables concurrent operations frommultiple nodes to store data to the same target node and file space in parallel.Enabling multiple node operation from the GUIThere are some steps you must follow to enable multiple node operation from theGUI.1. Verify that the client node has proxy authority to a target node (or authorizedto act as the target node) using the query proxynode administrative clientcommand.2. Select Edit → Preferences to open the preferences window.3. Select the General tab and fill in the As Node Name field with the name of thetarget node.4. Click Apply and then OK to close the preferences window.Perform one of the following steps to verify that your client node is now accessingthe server as the target node:vvOpen the tree window and check that the target node name specified by the AsNode Name field appears.Verify the target node name in the Accessing As Node field in the ConnectionInformation window.To return to single node operation, delete the As Node Name from the AccessingAs Node field in the General → Preferences tab.Chapter 4.
