In the TSM software, by default, a client node can access only the backup storage objects that it creates. For instance, when a backup is performed on client node1, all ARCMAIN backups are registered in the TSM server catalog as belonging to node1 and all other nodes are prevented from accessing the storage objects created by node1. However, it is possible to grant authorization for nodes to access other backups by creating a pseudo node that is used by all clients performing backups.
To create a pseudo node, use the TSM register node command that provides the node name and password. Then set the BACKDELETE option to YES. If this option is not set to YES, backup objects cannot be deleted with the TDDSMC utility. For information about the TSM register node command, refer to the Tivoli Storage Manager Administrators Guide on the IBM web site.
