Hardware Problems Predictive Failure Alert The predictive failure alert is a powerful problem-prevention tool that warns you when the system has determined that a drive failure is imminent. This alert allows you to proactively schedule downtime for maintenance and not interrupt critical business operations that rely on your server. In addition, with hot-pluggable drives connected to Smart Array Controllers you can remove and replace one or several drives within a server while the system is online. This minimizes the interruption of the network, server downtime, and data loss. Refer to your Insight Manager 7 (or previous version) and Management Agents documentation, found on the Management CD, for instructions on implementing this function. CAUTION: Failure to follow these guidelines can result in data loss. IMPORTANT: It is recommended that some level of fault tolerance be utilized in your RAID configuration. Refer to the Smart Array Controller user guide for information on fault-tolerance options. IMPORTANT: You must use Insight Manager 7 (or previous version) and a Smart Array Controller to manage the drive array on your server if you wish to implement the predictive failure alert. Predictive Failure Replacement Guidelines To minimize server downtime and data loss, use these guidelines when Insight Manager 7 (or previous version) issues a predictive failure alert. The alert indicates that a drive is degraded and should be replaced. • Be sure that all physical drives in the affected array are present and that the online LEDs are illuminated before removing the degraded hot-plug drive. If any online LEDs are flashing (indicating a rebuild) or are not illuminated, the degraded drive should not be removed. For step-by-step instructions on connecting a hot-plug hard drive, refer to the user documentation for your server. • If you are upgrading to larger drives in the array, follow the previously stated rules and be sure that each drive has completed its rebuild before adding the next new drive to the array. 2-30 HP Servers Troubleshooting Guide
