Technical Changes for Version 5 Release 1--March 2002

The following changes have been made to the product for this edition:

Changes in Defining Drives and Libraries

Device special file names and external library managers are now specified in the DEFINE PATH and UPDATE PATH commands, rather than in the DEFINE DRIVE, UPDATE DRIVE, DEFINE LIBRARY, and UPDATE LIBRARY commands.

See Chapter 5, Configuring Storage Devices. Also see Tivoli Storage Manager Administrator's Reference.

Moving Data by Node
You can use the MOVE NODEDATA command to move data in a sequential-access storage pool for one or more nodes, or move selected file spaces for a single node. You can also use MOVE NODEDATA to move data to another storage pool.

See Chapter 9, Managing Storage Pools and Volumes.

Support for Simultaneous Writes to Primary and Copy Storage Pools
You can specify copy storage pools in a primary storage pool definition. When a client backs up, archives, or migrates a file, the file is written to the primary storage pool and is simultaneously stored into each copy storage pool.

See Chapter 9, Managing Storage Pools and Volumes.

High Availability Cluster Multiprocessing
Tivoli Storage Manager can now use High Availability Cluster Multiprocessing (HACMP). HACMP provides the leading AIX-based clustering solution, which allows automatic system recovery during system failure detection. By using HACMP together with Tivoli Storage Manager, you can ensure server availability.

Tivoli Data Protection for New Network Data Management Protocol Support

New Network Data Management Protocol (NDMP) support now extends to the AIX (32-bit and 64-bit) Tivoli Storage Manager server platform. The new Tivoli Data Protection for NDMP product supports NDMP backup and restore for network-attached storage (NAS) file servers from Network Appliance. NDMP allows a network storage-management application to control the backup and restore of an NDMP-compliant file server without installing third-party software on that server. The NAS file server does not require installation of TSM software. The TSM server uses NDMP to connect to the NAS file server to initiate, control, and monitor a file system backup or restore operation. The NDMP support for NAS file servers enables higher performance backup to tape devices without moving the data over the LAN. TDP for NDMP is a separately priced and licensed product.

See Chapter 6, Setting Up Tivoli Data Protection for NDMP.

Data Validation with Cyclic Redundancy Checking
Tivoli Storage Manager provides the option of specifying whether a cyclic redundancy check (CRC) is performed during a client session with the server, or for storage pools. The server validates the data by using a cyclic redundancy check which can help identify data corruption. Data validation can be enabled for one or all of the following:

New Licensing Method
The new licensing method enables you to register the exact number of licenses that are required, rather than in increments of 1, 5, 10, and 50.

See Registering Licensed Features.

Server Performance Enhancements
There are two new Tivoli Storage Manager performance enhancements:

See Using Server Performance Options.
