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
( http://www.hp.com ).)
Diagnostic tools
Several diagnostic tools provide feedback about problems with arrays.
• ADU
This utility is available on the SmartStart CD in the controller kit and also on the HP website
(
http://www.hp.com/support ). For more information about the meanings of the various ADU error
messages, see the HP Servers Troubleshooting Guide.
• Event Notification Service
This utility reports array events to the Microsoft® Windows® system event log and the Integrated
Management Log. You can obtain the utility from the SmartStart CD or 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 HP Servers Troubleshooting Guide.
• HP Insight Diagnostics
HP Insight Diagnostics is a tool that displays information about the system hardware configuration
and performs tests on the system and its components (including hard drives if they are connected to
Smart Array controllers). This utility is available on the SmartStart CD and also on the HP website
( http://www.hp.com/servers/diags ).
