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
to collect all possible information about the array controllers in the system and to offer a
list of all detected problems.
NOTE:
Refer to the
Drive Array Advanced Diagnostics User Guide
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, sent to
Compaq for analysis. In most cases, DAAD provides 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.
