Compaq Fibre Channel Backup Diagnostics for
Windows NT
The Compaq Fibre Channel Diagnostics is a group of hardware diagnostic tests designed to the
Compaq StorageWorks Enterprise Backup Solution. This is a subset of the normal Compaq
Diagnostics for Windows NT specifically to help identify any potential problems with the Fibre
Channel Tape Controller and the DLT 15 Cartridge Library Model 3570 on the Fibre Channel
Arbitrated Loop. It can also be used to upgrade firmware for the Fibre Channel Tape Controller,
the Fiber Channel Tape Controller II, and the DLT Cartridge Library Model 3570.
It is important to note this subset of the Compaq Fibre Channel Backup Diagnostics for
Windows NT can not coexist with normal Compaq Diagnostics for Windows NT potentially
already installed. For the safest operation when switching between the two versions, be sure to
uninstall the current version and install the desired version according to the procedures below.
This ensures proper updating of the registry and other directories.

Channel Tape Controller) and any devices attached. The information returned for each device is
as follows:
