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 Intelligent Drive Array
Controller (IDA), COMPAQ Intelligent Drive Array Controller-2 (IDA-2), or
COMPAQ 32-Bit IDA Expansion Controller. 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, for 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.
Starting DAAD
To start DAAD:
1. Insert the DAAD diskette into drive A and reboot the system. If you are
at the DOS prompt, enter the following:
A:DAAD
2. A dialog box displays indicating the version of DAAD installed. Press
the Enter key to continue.
To exit without continuing, press the Esc key.
3. If you continue, a "Please Wait" panel will display indicating that
DAAD is identifying the system parameters.
DAAD gathers all the information it can from all of the array
controllers in the system. The time it takes to gather this information
depends on the size of your system.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Do not cycle the power because the utility must perform low-level
operations that, if interrupted, could cause the controller to revert back
to a previous level of firmware if the firmware was soft-upgraded.
1. Replace with a working pointing
device and retest.
2. Replace the system board and
retest.
