Diagnostic tools
Several diagnostic tools provide feedback about problems with arrays. The most important are:
• ADU
This utility is a Windows®-based diagnostic tool that sends an email to HP Support when it detects
any problems with the controllers and attached storage in a system.
You can install ADU from the Smart Setup media. When installation is complete, run ADU by clicking
Start and selecting Programs>HP System Tools>HP Array Diagnostic Utility.
The meanings of the various ADU error messages are provided in the HP Servers Troubleshooting
Guide.
• POST messages
Smart Array controllers produce diagnostic error messages at reboot. Many of these POST messages
are self-explanatory and suggest corrective actions. For more information about POST messages,
refer to the HP Servers Troubleshooting Guide.
