Removing a drive may terminate the current operation and cause data loss. The drive is rebuilding or undergoing capacity expansion. Do not remove the drive. The drive is being accessed, but (1) it is not configured as part of an array; (2) it is a replacement drive and rebuild has not yet started; or (3) it is spinning up during the POST sequence. Do not remove the drive. Removing a drive may cause data loss in non-fault-tolerant configurations. Either (1) the drive is part of an array being selected by an array configuration utility; (2) Drive Identification has been selected in HP SIM; or (3) drive firmware is being updated. The drive has failed and has been placed offline. You may replace the drive. Either (1) the drive is not configured as part of an array; (2) the drive is configured as part of an array, but it is a replacement drive that is not being accessed or being rebuilt yet; or (3) the drive is configured as an online spare. If the drive is connected to an array controller, you may replace the drive online. Recognizing hard drive failure A steadily glowing Fault LED indicates that that drive has failed. Other means by which hard drive failure is revealed are: • The amber LED on the front of a storage system illuminates if failed drives are inside. (However, this LED also illuminates when other problems occur, such as when a fan fails, a redundant power supply fails, or the system overheats.) • A POST message lists failed drives whenever the system is restarted, as long as the controller detects at least one functional drive. • ACU represents failed drives with a distinctive icon. • Systems Insight Manager can detect failed drives remotely across a network. (For more information about Systems Insight Manager, refer to the documentation on the Management CD.) • ADU lists all failed drives. For additional information about diagnosing hard drive problems, refer to the HP Servers Troubleshooting Guide. CAUTION: Sometimes, a drive that has previously been failed by the controller may seem to be operational after the system is power-cycled or (for a hot-pluggable drive) after the drive has been removed and reinserted. However, continued use of such marginal drives may eventually result in data loss. Replace the marginal drive as soon as possible. Effects of a hard drive failure When a hard drive fails, all logical drives that are in the same array are affected. Each logical drive in an array may be using a different fault-tolerance method, so each logical drive can be affected differently. Replacing, moving, or adding hard drives 23
