Navigate to the Delete Array button and hit Enter to bring up the
Delete Disk Array display. Check that the correct drives are listed.
Select the OK key to confirm deleting the array or Cancel to reject
it. Recall that the array is not actually deleted and no data will be
overwritten until you have finished making all your changes and
selected the F8 key.

How to maintain or verify a disk array

The Maintain Disk Array (see Figure 12) shows the current disk
array configuration that you have selected. The array's Write
Cache State can be changed. Refer to Select write cache proper-
ties paragraph in the Creating a disk array section. Verify Array
can be specified as no or yes. The default is no. Yes launches a fore-
ground process that checks the data integrity of a fault tolerant

Note:
Fault tolerant arrays can not be verified until
after they are initialized. For RAID 1 and 10 arrays the
initial verify must first be done in 3DM, otherwise the
initialization will not be done.

Rebuilding a mirrored disk array

Escalade ATA RAID Controllers allow you to create fault tolerant
disk arrays by selecting a mirrored RAID 1 or RAID 10 array.
These disk arrays store identical data on two or more drives to pro-
tect against drive failure. If one or more of the drives of a mirrored
