Diagnostics tasks
The ACU Diagnostics feature replaces the Array Diagnostic Utility supported by SmartStart v8.20 and
earlier. For each controller, or for all of them, you can select the following tasks:
• View Diagnostic Report—ACU generates and displays the diagnostic report.
• Generate Diagnostic Report—ACU generates a report without the graphical display.
For either task, you can save the report. In the SmartStart environment, you can save the report to a
formatted diskette or USB device. In online and offline environments, ACU saves the diagnostic report to a
compressed folder, which contains an XML report, a plain text report, and a viewer file so you can
display and navigate the report through a web browser.
Each ACU Diagnostics report contains a consolidated view of any error or warning conditions
encountered. It also provides detailed information for every storage device, including the following:
• Device status
• Configuration flags
• Firmware version numbers
• Physical drive error logs
ACU Diagnostics never collects information about the data content of logical drives. The diagnostic report
does not collect or include the following:
• File system types, contents, or status
