Verifying Arrays

If a mirrored or RAID 5 array becomes inconsistent,
data will be lost if an array drive fails. Follow these
steps to verify the consistency of data on an array:
1
From the Main menu for the array, select Verify
Functions.
2
Select Start Verify.
3
Indicate the priority of the operation by typing a
number from 0 through 9 (0 = lowest priority;
9 = highest priority).
To schedule routine verifications, see Scheduling
Tasks on page 8.
Reconstructing Data
Follow these steps to reconstruct data on a replace-
ment disk if a disk fails in a mirrored or RAID 5 array
and no spare disk is available. (If a spare is available,
the spare replaces the failed disk and the data is
reconstructed automatically.):
1
Physically replace the failed disk, if necessary.
Note:
If your drive enclosure requires all host
adapter activity to stop while you replace a
drive, select Hot Swap Pause before you
replace the drive. When you have finished,
press any key to resume SCSI bus activity.
2
From the Main menu for the array, select
Reconstruct Functions.
3
Select the reconstruction option you want. If the
array is mirrored, for example, select Re-mirror
Single Drive or Re-mirror all DOWN Drives.
4
Indicate the priority of the operation by typing a
number from 0 through 9 (0 = lowest priority;
9 = highest priority).
