Diagnostic tools

Several diagnostic tools provide feedback about problems with arrays. The most important are:

•ADU

This utility is available on both the SmartStart CD and the HP website (http://www.hp.com/support). 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.

•Server Diagnostics

To use Server Diagnostics:

a.Insert the SmartStart CD into the server CD-ROM drive.

b.Click Agree when the license agreement appears, and click the Maintenance tab.

c.Click Server Diagnostics, and follow the on-screen prompts and instructions.
