Scheduling a Parity Check
Select Array Administration > Schedule Parity Check to check parity of a specific logical array at scheduled intervals (for example, during off hours).
You can choose to schedule any number of logical drives configured on a
managed server; however, you can establish only one schedule per array controller.
When you schedule multiple logical drives, the check is done in sequence
from the lowest to the highest numbered logical drive.
A parity check requires an average of five minutes per Gbyte of storage.
You can control the amount of resources allocated to the parity check
by changing the rebuild priority. See Rebuild Priority.
A parity check can be stopped once it has started.

-
Select the controller on which you want to schedule the parity check.
-
Select Array Administration > Schedule Parity Check.
