To verify or rebuild parity for a RAID array:
1
In the RAID Admin window, click Advanced.
2
If necessary, enter the management password and click OK.
3
Select Verify or Rebuild Parity and click Continue.
4
In the Verify or Rebuild window, select the array for which you want to verify or rebuild
parity data.
5
Select Verify or Rebuild.
The controller automatically selects available drives to add to the array.
6
Click the confirmation checkbox to confirm that you want to verify or rebuild.
7
Click Verify Array or Rebuild Array.
Note: The verification or rebuilding procedure takes a number of hours. You can
continue to use the array during this procedure.
If verifying parity data detects a problem, the recommended procedure for repair is as
follows:
•
Perform an integrity check of the file system in the Finder.
•
Verify data on the volumes.
•
Use the rebuild function to rebuild the array’s parity data.
Rebuilding parity on an array does not repair any problems with the data on the array.
Rather, the data that is present on the array is used to create new parity data.
