8 Repeat this procedure for all LUNs and hosts you want to map, using the Add Host
button to enter a new WWPN for that host.
9 You can make other adjustments in LUN masking with the buttons below the list of
LUNs on the right. These adjustments include:
• All On: maps all LUNs to the selected host
• All Off: maps no LUNs to the selected host
• Copy: copies LUN map settings for the selected host
• Paste: applies the previously copied LUN map settings to the selected host
10 Click OK.
The LUN masking takes effect when the Xserve RAID system restarts.
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).
