Storage Fault Recovery Tracking The feature tracks over 12 failure-indication parameters, such as time-outs, spin-up, and self-test errors of SCSI drives. You can use these parameters to pinpoint failed storage subsystem components and to recover from controller or hard drive failure. Storage Automatic Reconstruction The feature automatically reconstructs data to an online spare or to a replaced drive if a drive fails. To use the reconstruction feature, you must configure the server for drive mirroring or data guarding. The reconstruction decreases system downtime by allowing enabling recovery to full system operation if a drive fails.

errors of SCSI drives. You can use these parameters to pinpoint failed storage subsystem
components and to recover from controller or hard drive failure.
Storage Automatic Reconstruction
The feature automatically reconstructs data to an online spare or to a replaced drive if a drive
fails. To use the reconstruction feature, you must configure the server for drive mirroring or data
guarding. The reconstruction decreases system downtime by allowing enabling recovery to full
system operation if a drive fails.
