• Mirrored Memory Mode-Provides protection against uncorrectable memory errors that would otherwise result in system failure. In this mode, the system maintains two copies of all data. If an uncorrectable memory error occurs, the system automatically retrieves the good data from the mirrored copy. The system continues to operate normally without any user intervention. If the system supports hot-plug memory, the failed memory can be replaced while the system continues to operate. • RAID Memory Mode-Provides protection levels similar to Mirrored Memory Mode, and it requires less memory allocation than full redundancy. Array Configuration Utility ACU is a browser-based utility with the following features: • Runs as a local application or remote service • Supports online array capacity expansion, logical drive extension, assignment of online spares, and RAID or stripe size migration • Suggests the optimum configuration for an unconfigured system • Provides different operating modes, enabling faster configuration or greater control over the configuration options • Remains available any time that the server is on • Displays on-screen tips for individual steps of a configuration procedure For optimum performance, the minimum display settings are 800 × 600 resolution and 256 colors. Servers running Microsoft® operating systems require Internet Explorer 5.5 (with Service Pack 1) or later. For Linux servers, refer to the README.TXT file for additional browser and support information. For more information, refer to the Configuring Arrays on HP Smart Array Controllers Reference Guide on the Documentation CD or the HP website (http://www.hp.com). 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 Software tools and solutions 67
