- Tivoli Storage Manager Device Driver
- The Tivoli Storage Manager Server device driver is now available on
HP-UX. It replaces the use of the SCSI Pass-through driver for
autochangers, and can be used to optimally support SCSI tape and optical
drives.
See Chapter 4, Attaching Devices to the Server System.
- LAN-Free Data Movement
- Tivoli Storage Manager supports LAN-free data movement in storage area
network (SAN) environments. The support allows client data to move
directly from the client system to a server-managed storage device on the
SAN. This enhancement reduces data movement on the LAN so that more
bandwidth is available to other applications.
See LAN-Free Data Movement.
See Tivoli Storage Manager Managed System for SAN Storage Agent
User's Guide for more information.
- Devices Attached to HP Systems that Use Precision Bus SCSI Adapters
- Devices attached to HP systems that use Precision Bus SCSI adapters are no
longer supported. This is because the architecture is no longer
current. If you are using such a system, do not migrate to Version
5.1.
- Changes in Defining Drives and Libraries
-
Device special file names 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.
- Tivoli Data Protection for New Network Data Management Protocol Support
-
New Network Data Management Protocol (NDMP) support now extends to the
HP-UX (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.
