Error Recovery Storage Fault Recovery Tracking This feature tracks more than 12 failure-indication parameters for SCSI drives, such as time-out, spin-up, and self-test errors. You can use these parameters to pinpoint failed storage subsystem components and to recover from controller or hard drive failures. Storage Automatic Reconstruction This feature automatically reconstructs data to an online spare drive or to a replaced drive if a drive fails. To use the reconstruction feature, you must configure your server for drive mirroring or data guarding. The reconstruction decreases system downtime by allowing rapid recovery to full system operation. Network Interface Fault Recovery Tracking This feature tracks over 20 failure indication parameters, such as alignment errors, lost frames, and frame copy errors, of Ethernet and IBM Token-Ring network interfaces. Network interface fault recovery tracking decreases network downtime by enabling diagnosis of actual network interface failures. Memory Fault Recovery Tracking This feature inspects the operation of the memory subsystem looking for noncorrectable memory errors. HP Servers Troubleshooting Guide 5-19
