IMPORTANT:
Note the following for the Reconstruction:
● Be sure to make backup copy of data and perform Consistency
Check before starting Reconstruction.
● The Reconstruction is disabled in the configuration where several
virtual disks are defined in one disk group
● During Reconstruction, the processing rate is decreased due to
heavy load.
● The Reconstruction can be performed for the degraded virtual disk.
However, it is recommended to execute Rebuild to recover the
virtual disk, then execute Reconstruction.
● During Reconstruction, do not shutdown or reboot the server.
● In some configuration, Background Initialize may start
automatically upon completion of Reconstruction.
