Check for Consistency
For redundant-type arrays only, the Consistency Check task is available from the Array drop-down menu.
When this task is selected it starts the process of verifying that the parity (RAID 5) or mirror drive consistency
is correct. If inconsistent areas are found, they are corrected during this process.
Having consistent arrays is very important. If an array is inconsistent and a drive fails, data is lost. RAIDCore is
designed to maintain consistent arrays, but it is good practice to frequently run consistency checks. See
Schedule a Consistency Check
on page 89.
When a redundant array is created using the Create task, and the Skip Initialize option is not checked (the
default setting), a Consistency Check is performed automatically. Although a Consistency Check that runs
during a Create task can be removed (by highlighting the array and selecting
Task
->
Remove
), the array that
is created will not be redundant. Unless a Consistency Check runs from end-to-end, an array is not protected.
After a Consistency Check has been started, adjust the priority of the Consistency Check task relative to user
I/O activity. Use the Task Priority option (see
Change the Priority Level of a Task
on page 87).
A Consistency Check task can be scheduled with the Schedule Consistency Check task (see
Schedule a
Consistency Check
on page 89).
Before you begin...
•
A Consistency Check task can be started at any time on a redundant-type array, as long as another task is
not running on the array.
•
If the array state is Critical, the Consistency Check fails.
•
A Consistency Check task can be started while under I/O load.
•
To estimate how long the Consistency Check will take, look at the percentage of the task that is completed
and the estimate of the remaining time (hours: minutes: seconds). These details are displayed next to the
array in the Array View section of the Array Status window.
Manually start a Consistency Check

Check Consistency
task.
