Array Diagnostic Utility (ADU)
The Array Diagnostic Utility (ADU) is a Windows-based software tool designed to run on all
Compaq servers that support Compaq array controllers installed with SmartStart 4.10 or later.
The two main functions of The 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.
The 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, the ADU provides enough information to initiate problem
resolution immediately.
NOTE: The ADU does not write to the drives, destroy data, or change or remove configuration
information.
Starting the ADU
1. Insert the SmartStart CD into the CD-ROM drive.
2. Restart the system from the SmartStart CD.
3. Select Array Diagnostic Utility (ADU) from the System Utilities menu.
A “Please Wait” panel displays, indicating that the ADU is identifying the system
parameters. The 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, the ADU displays the main screen or a panel
indicating any problems detected.
CAUTION: Do not cycle the power during this process. The 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 select Save Data from the Command menu.
