Managing client nodes across a firewall
In most cases, the IBM Tivoli Storage Manager server and clients can work across a firewall or the server can securely manage client backup and restore operations and administrative functions across a firewall. Because every firewall is different, the firewall administrator might need to consult the instructions for the firewall software or hardware in use.

Updating client node information
You can issue the UPDATE NODE command to update information such as the client's assigned policy domain, the user's password or contact information, and the client option set used by the node.

Automatic deployment feature for the backup-archive client
The backup-archive client automatic deployment feature helps you schedule updates to one or more backup-archive clients. The updates can be fix packs or new releases.

Renaming client nodes
You can rename a client node by issuing the RENAME NODE command. You might need to rename a client node if the workstation network name or host name changes. For example, with UNIX and Linux clients, users define their node name based on the value returned by the HOSTNAME command.

Locking and unlocking client nodes
You can prevent client nodes from accessing the server with the LOCK NODE command. This prevents client nodes from performing functions such as either backup and restore or archive and retrieve.

Deleting client nodes
You can delete a client node from the server with the REMOVE NODE command. All file spaces that belong to the client node must first be deleted from server storage. After all of the client node's file spaces are deleted, you can delete the node.

Consolidating multiple clients under a single client node name
Backups of multiple nodes which share storage can be consolidated to a common target node name on the Tivoli Storage Manager server. For example, several nodes in an IBM General Parallel File System (GPFS™) cluster, NODE_1, NODE_2, and NODE_3, can back up to the same node (NODE_OLIV) on the server.

Displaying information about client nodes
You can display information about client nodes in different aspects.

Overview of remote access to web backup-archive clients
With the introduction of the web backup-archive client, when a client node is registered with an IBM Tivoli Storage Manager server, an identical administrative user ID is created at the same time. This user ID has client owner authority over the node by default.

Managing client access authority levels
By default, an administrator with system or policy privilege over a client's domain can remotely access clients and perform backup and restore operations.
