Rebuild
Choose the Rebuild option to rebuild one or more failed disk drives. Select [Abort
Rebuild] to stop the rebuild process at any time. The drive will revert to its original status
before the rebuild began.
A RAID 1 or 5 configuration has redundancy. If a drive in a RAID group fails, the RAID
subsystem continues to work but no additional redundancy is provided. Another drive
failure will bring the system down. But the failed drive can be replaced and added into the
RAID system by rebuilding the drive. Select Rebuild to perform this function. The rebuild
process can take place while the RAID system is still running, although performance may
be slightly affected.
