1 Introduction
HP Library and Tape Tools (L&TT) is a collection of storage hardware management and diagnostic
tools for HP tape mechanisms, tape automation, magneto-optical and archival products. L&TT
assembles these tools into a single, convenient program.
LTT 5.x is a new architecture that combines the diagnostics functionality of L&TT 4.x with the
monitoring capability of TapeAssure, and that can be installed in different configurations to offer
flexible usage models all accessed through a web based GUI.
LTT 5.x is delivered in two components; the LTT Service and the WebGUI. The LTT Service runs on
the server that controls the library and tape drives. The WebGUI can be installed on any
Windows-based system that can access the LTT Service. This architecture provides two distinct use
models:
•
Single server – The LTT Service and WebGUI can be installed on the same server for a simple,
localhost-based configuration. Monitoring and diagnostics all run on the same server.
•
Multiple server – The LTT Service is installed on each of the servers that control supported
storage devices with the WebGUI installed on a single computer. With this configuration, you
can monitor drives and run diagnostics on all the servers from a single user interface.

The architecture also enables remote access, either by installing the WebGUI on a local system,
such as a laptop, or the WebGUI can be accessed from a browser on any connected Windows
system. Note that the WebGUI can be installed on more than one system, allowing diagnostic
access from any of those systems, but the monitoring should always be consolidated onto a single
WebGUI so you can see all the systems you are monitoring at the same time. Also, with all the
monitoring data on a single computer, the L&TT algorithms that compare drive and tape health for
multiple drives and tapes are more accurate.
Access to the devices (from the LTT Service) is also improved such that in most cases, there is no
need to stop the backup or application services to pull tickets or run tests. The backup or archive
application should be stopped before running any active tests but the services can be left running.
In addition to having an improved user interface and flexible configurations, LTT 5.x is also easier
to use for running tests, pulling support tickets, and sending test results and tickets by email.
