Array Diagnostic Utility (ADU)
Array Diagnostic Utility (ADU) is a Windows-based software tool designed to run on all
Compaq servers that support Compaq array controllers, and are running SmartStart 4.10 or later.
The two main functions of ADU are to collect all possible information about array controllers in
the system and to generate a list of detected problems. The error messages and codes listed
include all codes generated by Compaq products. The system generates only codes applicable to
the configuration and options in the server.
ADU works by issuing multiple commands to the array controllers to determine if a problem
exists. This data can then be saved to a file. In severe situations, this file can be sent to Compaq
for analysis. In most cases, ADU provides enough information to initiate problem resolution
immediately.
NOTE: ADU does not write to the drives, destroy data, or change or remove configuration information.
Starting ADU
1. Insert the SmartStart CD into the CD-ROM drive.
2. Reboot the system from the SmartStart CD.
3. Select Array Diagnostic Utility (ADU) from the System Utilities menu.
A “Please Wait” panel displays, indicating that ADU is identifying the system parameters.
ADU gathers information from all of the array controllers in the system. The time it takes to
gather this information depends on the size of the system. When the information gathering
process is complete, ADU displays the main screen or a panel indicating any problems
detected.
CAUTION: Do not cycle the power during this process. ADU must perform low-level operations
that, if interrupted, could cause the controller to revert to a previous level of firmware if the
firmware was soft-upgraded.
4. To generate an ADU report, select File then Save Data from the command menu.
