HP StoreEver MSL6480 Tape Library User and Service Guide

• Do not back up individual mailboxes.
• Do not back up specific records or do a record-by-record backup.
• Do not back up when the database is in heavy use.
Connection from the archive/backup host server to the library
For the best performance, the connection from the host server to the library must have enough
bandwidth to provide enough data to keep the tape drive streaming. Current LTO tape drives take
advantage of some of the fastest interfaces available so the type of interface used to connect the
library to the host server is not likely to be the cause of a performance issue. However, issues with
cables and connectors can limit performance.
Verify that the system is using cables that are listed in the QuickSpecs, are in good condition, and
do not exceed recommended cable lengths.
Media
The type and condition of the media also affect backup performance. For best performance, use
HP media that is the same LTO generation as the tape drives. If you suspect a performance issue
related to media, use the L&TT media assessment test to evaluate the condition of the tapes.
Using HP Library & Tape Tools to diagnose problems
With HP Library & Tape Tools installed on the host server you can:
• View detailed configuration, identification, inventory, and drive information for the devices
attached to the server.
• Easily update device and drive firmware.
• Run advanced diagnostic tests, including connectivity, read/write, media validation, and
testing the functionality of the device.
• View device and drive error logs.
• Generate a detailed support ticket that can be e-mailed or faxed to your support representative
for analysis.
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.
• L&TT 4.x is a single, small executable with some functionality not yet available in L&TT 5.x.
L&TT 4.16 and newer versions support the MSL6480 library.
• L&TT 5.x is a new architecture that combines the diagnostics functionality of L&TT 4.x with the
monitoring capability of TapeAssure, that can be installed in different configurations to offer
flexible usage models all accessed through a web based GUI. L&TT 5.1 and newer versions
support the MSL6480 library.
L&TT can be downloaded free of charge from www.hp.com/support/TapeTools.
To diagnose problems with L&TT:
1. Install L&TT using the instructions from the applicable L&TT user guide.
2. Generate a support ticket for the library.
3. Look at the device analysis results for additional information about the library’s operation.
