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 data in a single node with selected file spaces. You can also use MOVE NODEDATA to consolidate data for offsite disaster recovery storage, or move data to another storage pool.

See Administrator's Guide for more information.

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 Administrator's Guide for more information.

See the following changed commands:

DEFINE STGPOOL

QUERY SESSION

QUERY STGPOOL

REGISTER NODE

UPDATE NODE

UPDATE STGPOOL

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 Manger, you can ensure server availability.

See Administrator's Guide for more information.

Tivoli Data Protection for New Network Data Management Protocol Support

New Network Data Management Protocol (NDMP) support now extends to the AIX(R) (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 IBM and 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 Administrator's Guide for more information.

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:
