Notice
Note the following for the reconstruction:
Be sure to make a backup copy of data before starting reconstruction.
Reconstruction is disabled in a configuration where several virtual disks are defined in
one disk group
During reconstruction, the responsiveness of the server decreases due to high load.
Reconstruction is disabled for a degraded virtual disk. First, execute rebuild to recover
the virtual disk, and then execute reconstruction.
During reconstruction, do not shutdown or reboot the server. If the server is shutdown
accidentally due to power interruption, turn on the power as soon as possible.
Reconstruction is automatically restarted.
