Parity Verify
To access this function, from the Advanced Setup menu:

Drive screen.

Select the Parity Verify option and press Enter.
The redundancy information calculated during an array build or rebuild is stored on a
dedicated logical drive (RAID 4), or is distributed over all logical drives of the array drive
(RAID 5). This information is often called
parity data . The calculation is made with an
exclusive OR function (XOR). If a logical drive of an array drive fails, its data can be
recalculated by means of the data present on the other logical drives of the array drive and
the parity data. The
Parity Verify function allows you to check the consistency of an array
drive's parity data. The verification may take quite a long time, but you can terminate it by
pressing <Esc>.
Note:
If you press the escape key <Esc>, the progress indicator ( Figure 10-87 ) will close.
However, parity verify continues to run unless you press the <A> key to abort the parity
verify.
Note:
Parity verify has the capability to repair bad parity sectors automatically.
