Chapter 4 Using Advanced Features of RAID Admin 39
The RAID controller begins restriping data across all the drives. The added drives’
capacity is added to the array as an unmapped slice. To make the added drive or drives
available to the array, merge the slices on that array.
To complete the expansion procedure by merging:

Return to the Advanced window, select Slicing, and merge the slices on the array that
you just expanded.
See “Merging Slices in an Array” on page 37 for details on merging slices.
Verifying or Rebuilding Parity for an Array
You can verify the integrity of an array that uses parity (RAID 3 or 5) on an Xserve RAID
system. If necessary, you can also rebuild the parity data for an array.
Note: Verifying or rebuilding parity on an array does not affect the file system or the
data on the array. These procedures make sure the array’s data is protected and verify
the integrity of the RAID set.
When you verify or rebuild parity for an array, the operation takes several hours and the
results are reported in the list of events (in the Events pane of the RAID Admin
window).
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.
