Rebuild Array
The Rebuild Array option allows you to rebuild a disk in the array while the
system is running without disrupting user or application access to the data set.
Note:
Rebuilding an array can take up to a full day to complete. This operation
occurs in the background and does not impede any work being done. If you
need to shutdown, the rebuild operation continues upon restart.
Use the following procedure to rebuild an array:
9. Identify the affect disk in the array and replace it.
10. Click on
Rebuild Array under Management to launch the NVIDIA Rebuild
Array Wizard.
11. Click Next to continue with the wizard and display the RAID Array
Selection menu.
12. Select the array with that had the affected disk and click Next.
Rebuilding a degrading array adds a new disk to that array. Data from the
healthy disk is rebuilt onto a new disk.
Note:
Rebuilding a healthy RAID array resynchronizes the data set onto a disk.
