Drive Array Advanced Diagnostics
(DAAD)
Drive Array Advanced Diagnostics (DAAD) is a DOS-based tool designed to run on all
Compaq products that contain a Compaq Drive Array Controller. The error messages and
codes listed include all codes generated by Compaq products. Your system generates only
codes applicable to your configuration and options.
The two main functions of DAAD are:
■
Collecting all possible information about array controllers in the system
■
Offering a list of all detected problems
NOTE
: Refer to the
Drive Array Advanced Diagnostics User Guide,
found
on the SmartStart CD
,
for complete details and procedures about this
diagnostic tool.
DAAD works by issuing multiple commands to the array controllers to determine if a problem
exists. This data can then be saved to a file and, in severe situations, this file can be sent to
Compaq for analysis. In most cases, DAAD will provide enough information to initiate
problem resolution immediately.
NOTE
: DAAD does not write to the drives or destroy data. It does not
change or remove configuration information.
