Tivoli Storage Manager for Sun Solaris Administrator's Guide


Registering Nodes with the Server

TSM administrators can register TSM clients, Tivoli Data Protection application clients, HSM clients, and TDP host servers as client nodes.

When a node is registered, TSM automatically creates an administrative user ID with client owner authority over the node. You can use this administrative user ID to access the Web backup-archive client from remote locations through a Web browser. If an administrative user ID already exists with the same name, an administrative user ID is not automatically defined. For more information, see Overview of Remote Access to Web Backup-Archive Clients.

Note:To connect to a Web backup-archive client directly from a supported Web browser or from a hyperlink in the Web administrative Enterpise Console, you must specify the node's URL and port number during the registration process or later update the node with this information.

Accepting Default Closed Registration or Enabling Open Registration

Before a user can request TSM services the node must be registered with the server.

Closed registration is the default at installation. The administrator must register client nodes when registration is set to closed.

Open registration allows the client nodes to register their node names, passwords, and compression options. On UNIX systems, only the root user can register a client node with the TSM server.

With either registration mode, by default, an administrative user ID with client owner authority is created over the node.

Note:Changes to the registration process do not affect existing registered client nodes.

Closed Registration

To add a node with closed registration, an administrator uses the REGISTER NODE command to register the node and specify the initial password.

The administrator can also specify the following optional parameters:

To add a node with closed registration, an administrator registers the node, specifies the initial password, compression options, the policy domain to which the node belongs, and whether the user can delete backups and archives from server storage.

Open Registration

To add a node with open registration, the server prompts the user for a node name, password, and contact information the first time the user attempts to connect to the server. The server allows users to delete archive copies, but not backups for the server. The server automatically assigns the node to the STANDARD policy domain. TSM administrators can enable open registration by entering the following command from an administrative client command line:

   set registration open

For examples and a list of open registration defaults, refer to the Administrator's Reference.

To change the defaults for a registered node, use the UPDATE NODE command.

Node Compression Considerations

When you enable compression, it reduces network utilization and saves server storage, but causes additional central processing unit (CPU) overhead to the node. Data compression is recommended only when there is insufficient network capacity. Server data compression has no effect on Tivoli Data Protection host server data.

Attention: Nodes should use either client compression or drive compression but not both. For details, see Using Data Compression.

To optimize performance or to ease memory constraints at the workstation, a TSM administrator can restrict file compression. You can select one of three options:

Registering Nodes with Client Options Sets

Administrators can use client options sets in conjunction with the client options file to register nodes with the server. Client option sets are considered advanced implementation and are discussed in Modifying Client Option Files. You can specify an option set for a node when you register or update the node. For example:

   register node mike pass2eng cloptset=engbackup

The client node MIKE is registered with the password pass2eng. When the client node MIKE performs a scheduling operation, the schedule log entries are kept for 5 days.

Registering a Source Server as a Node on a Target Server

A virtual volume is a volume that appears to be a sequential media volume on a source server. The volume is actually stored as an archive file on a target server.

To use virtual volumes, register the source server as a client node on the target server.

The REGISTER NODE and UPDATE NODE commands have a default parameter of TYPE=CLIENT. To register a source server as a node, you must specify the TYPE=SERVER parameter. For more information, see Using Virtual Volumes to Store Data on Another Server.

Registering an Application Programming Interface to the Server

Workstation users can request TSM services by using an application that uses the TSM application programming interface (API). An administrator uses the REGISTER NODE command to register the workstation as a node.

Understanding How to Set the Compression Option

For applications that use the TSM API, compression can be determined by:

For more information on setting options for the API and on controlling compression, see Tivoli Storage Manager Using the Application Program Interface.

Understanding How to Set the File Deletion Option

For applications that use the TSM API, the file deletion option can be set by:
