Install and Use RAID Administration and Monitoring Utilities
The RAID administration utility alerts the user via the speaker and display if a drive becomes DDD or if a Predictive Failure Analysis (PFA) alert occurs. PFA support on disk drives recognizes potentially bad drives, and alerts systems administrators allowing them to replace the unit before a catastrophic drive failure. The PFA alert prompts you to replace the drive before actual failure, so that a HSP is always present.
The RAID administration utility monitors RAID operations, displaying results on the RAID Administration Screen and logging these RAID events to a file. You can specify whether you want the utility to save the file to a diskette drive, local hard drive, or network hard drive, however, the recommended policy is to use the diskette drive or network drive. This practice makes it easier to recover from situations where the operating system is not accessible due to the failure. The logs themselves are required to recover data from systems when multiple DDD drives occur. The logs also provide essential RAID history for that server when troubleshooting and isolating the defective part in cases where it is not the drive that is defective.
