    5.0 Advanced Operations 5.1 Volume rebuild If one physical disk of the RG which is set as protected RAID level (e.g.: RAID 3, RAID 5, or RAID 6) is FAILED or has been unplugged / removed, then the status of RG is changed to degraded mode, the system will search/detect spare disk to rebuild the degraded RG to a complete one.
  • Page 73 Rebuild operation description: Disk striping. No protection for data. RG fails if any hard RAID 0 drive fails or is removed. Disk mirroring over 2 disks. RAID 1 allows one hard drive RAID 1 to fail or be removed. One new hard drive needs to be inserted into the system and the rebuild will complete.
