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:
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:
