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.
