• 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 then selecting Programs>HP System Tools>HP Array Diagnostic Utility.
For the meanings of the various ADU error messages, see the troubleshooting chapter in the server-
specific service guide.
• Event Notification Service
This utility reports array events to the Microsoft® Windows® system event log and the HP Integrity
System Event Log. You can obtain the utility from the HP website (http://www.hp.com/support
).
• POST messages
Smart Array controllers produce diagnostic error messages (POST messages) at reboot. Many POST
messages are self-explanatory and suggest corrective actions. For more information about POST
messages, see the troubleshooting chapter in the server-specific service guide.
