LED) Interpretation
Slow blink
(once every
16 seconds) This display pattern might occur after the system
is powered down. It indicates that the cache
contains data that has not yet been written to
the drives. Restore system power as soon as
possible to prevent data loss. (The battery
lifetime depends on the cache module size. For
further information, refer to the controller
QuickSpecs on the HP website
(

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.
To install ADU, open the
\contents\utilities\smartarray directory on the Smart Setup
media and double-click the cp00xxxx.exe file. 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.
