This display pattern occurs after the system is

powered down if the cache contains data that

has not yet been written to the drives. Restore

system power as soon as possible to prevent

data loss. (A fully charged battery pack can

preserve cached data for up to three days.)

The life expectancy of a battery pack is

typically three years or more, depending on the

cache module size. For further information, see

the controller QuickSpecs on the HP website

(http://www.hp.com

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.
