Users could set up the schedule for disk scrubbing for one or all arrays . After
select ON, users could select Once / Once per 1 week/Once per 4 weeks/
Once per 8 weeks/ Once per 12 weeks / Once per 16 weeks / Once per 20
weeks / Once per 24 weeks to execute scrubbing schedule function
When the array is not in the optimal state, the controller will
1.
give up disk scrubbing and record this event in the event
log. Or,
If the controller is not in power-on state at the schedule
2.
time, when restart, the controller will record this event to
notify users that the disk scrubbing is not executed.

Disk Clone
Disk Clone is like as mirroring, it's to prevent failure of hard disks from data
loss and unscheduled performance degradation.
It provides below advantage:
1. Disk cloning can be started and process without halting the host's normal
access, it will impact the system's overall performance.
2. Disk cloning can be started and process for multiple array
simultanelously.
Before disk cloning starts, the array must be in optimal state:
No failed member disk
No background task, such as adding a disk or disk scrubbing or
array expanding or degraded mode
After disk cloning starts,
No background task can be started for the array of the selected
source disk
Array cannot be deleted
User could stop disk cloning manually or by controller cause of
some exception conditions such as controller power off, disk
failures, array failure, or unrecoverable bad blocks on source
disk.
Start Disk Clone
Users can select this function if they want to do disk clone
