Features • Predictive failure alert is a powerful problem-prevention feature that warns you when a drive failure is imminent. This feature allows you to take corrective action with minimal effect on critical business operations. Your system must use Compaq Insight Manager and a Compaq Smart Array controller to benefit from predictive failure alert. Instructions for using the predictive failure alert feature can be found in the documentation for Compaq Insight Manager software and Compaq Management Agents. This documentation is located on the Compaq Management CD. NOTE: An online spare will not become active and start rebuilding after a predictive failure alert, because the degraded drive has not actually failed yet and is still online. The online spare is activated only after a drive in the array has failed. • POST or the Array Diagnostics Utility (ADU) also reveals imminent drive failure. • Recovery ROM is a controller redundancy feature that ensures continuous system availability by providing a backup ROM. This feature protects against corruption of a ROM image (caused, for example, by power fluctuation during ROM upgrade). If corruption occurs, the server automatically restarts using the remaining good copy of the ROM image. When you upgrade the ROM, the inactive image (the one not being used by the system) is upgraded. There is not normally any noticeable difference in operation. When you use Recovery ROM for the first time, however, the backup ROM images are upgraded, causing a boot delay of about 20 seconds. Other Compaq options, such as Compaq Insight Manager, provide additional drive failure features. See your Compaq authorized reseller for more information about these products.
