NOTE
In some literature, hot fix drives are also referred to as hot spare drives. You can also add or
remove hot spare drives using .
Remove Hot Fix Drive
This option allows you to remove a hot fix drive from an existing array drive.
Hot Fix Pool Access
By selecting the Hot Fix Pool Access option, the access of a specific array drive to the hot fix pool
can be enabled or disabled.
Parity Verify
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
When using the escape key <Esc>, the progress indicator will close. However, parity verify
continues to run unless the “A” key is used to abort parity verify.
✏
NOTE
Parity verify has the capability to repair bad parity sectors automatically.

Periodic Parity Verify
If the parity information of a given array drive is defective, the Parity Recalculate function may be
used to recalculate it.
Allows you to schedule parity verify activity as described in previous section. Configurable
variables include: Start Parity Verify (frequency of days to run, default is none), At Time (what
time to run on the days specified), and Error Handling (what to action to take when an error in
encountered during the parity verify).
