Automatic Drive Rebuild - Accusys ACS-8910 User Manual

2.2.3 Automatic Drive Rebuild

When one of the drive fails, the controller will check if there is any local spare drive assigned to this
logical drive first; If yes, the controller will start to rebuild lost data atomatically.
If not, the controller will search for a Global Spare Drive; if the Global Spare Drive is available, the
controller will auto-rebuild lost data.
If neither Local Spare Drive nor Global Spare Drive is available, the controller will not try to rebuild
unless the user applies a forced-manual rebuild.
