Array Configuration Utility
ACU Version 6.0 is a browser-based utility with the following features:
• Supports online array capacity expansion, logical drive capacity 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
The minimum display settings for optimum performance are 800 × 600 resolution
and 256 colors. The server must have Microsoft Internet Explorer 5.5 (with Service
Pack 1) installed and be running Microsoft Windows 2000, Windows NT 4.0, or
Linux. Refer to the README.TXT file for further information about browser and
Linux support.
For more information about ACU Version 6.0, refer to the HP Array Configuration
Utility User Guide on the Documentation CD.
Moving Array Controller Drives and Arrays
CAUTION: Back up all data before removing drives or changing configurations.
Failure to do so could result in permanent loss of data. Before moving drives and
arrays, run ACU.
Drives can be moved to other ID positions on the same array controller. You can also
move a complete array from one controller to another, even if the controllers are on
different servers or storage devices. Arrays on different controllers can also be moved
to another controller.
Before moving drives, observe the following requirements:
• No drives are failed, missing, or degraded.
• The move does not result in more than 14 physical drives.
