Rebuilding Arrays
NOTE: Rebuilding applies to Fault Tolerant arrays (RAID 1) only.
If an array Build process (or initialization) is interrupted or critical with one member missing, you must perform a Rebuild to
get the array to Optimal status. For a critical array Rebuild operation, the optimal drive is the source drive.
NOTE: If no spare exists and a hard disk drive fails, you need to create a spare before you can rebuild an array. See
" Add/Delete Hotspares " before continuing your Rebuild.
1. From the Main Menu, select Manage Arrays.
2. From the List of Arrays, select the array you want to rebuild.
3. Press <Ctrl><r> to rebuild.
Verifying Drives
If you are notified of a mismatch of data during a build of RAID 1, you have an option of synchronizing your drives.
NOTE: You only have the synchronize option available if the array is Optimal. If the array has failed, you need to
rebuild the array.
1. Select the drives you need to synchronize.
2. Press <Ctrl><s>.
3. Select Yes when the following prompt is displayed:
Do you want utility to automatically fix errors? (Yes/No)
When the synchronization is complete, you are notified with a fix message.
Deleting Arrays
NOTICE: Back up the data on an array before you delete it. Otherwise, all data on the array is lost. Deleted arrays
cannot be restored.
To delete an existing array:
1. Turn on your computer and press <Ctrl><a> when you are prompted to access the ARC utility.
2. From the ARC menu, select Array Configuration Utility (ACU) and press <Enter>.
3. From the ACU menu, select Manage Arrays using the up- and down-arrow keys.
4. Select the array you want to delete and press <Delete>.
