HP Library & Tape Tools

HP StorageWorks Library & Tape Tools (L&TT) is the recommended diagnostic and support tool for
your HP tape storage product. It is available on the CD shipped with your product or as a free
download from the HP web site. It is supported on nearly all major operating systems. See 

http://

www.hp.com/support/tapetools

 for compatibility information, updates and the latest version of the

tool.

Installing L&TT

The download version is preferred as it is the latest version.

Install L&TT on any server that can “see” your drive.

This is most likely to be the backup server, but it could be another server if you are using a SAN.

You will need the tape driver installed to run the performance tests.

Running L&TT

1.

Install L&TT.

2.

Turn off services that may lock the tape drive, such as backup software services and Removable
Storage Service (RSM).

3.

Double click on the desktop icon.

4.

Use defaults in pop-ups.
