To ensure the accuracy of the RAID parity data, RAID controller offers Background checking
and "Rebuild parity data." During checking or rebuilding parity, the performance of the array will
be affected. You could check the progress in the Main view or in the Health Center.
Follow the steps below to select an array to verify, rebuild, or condition.
1. Select the Array to verify, rebuild, or condition.
2. Click the radio button to:
Rebuild the parity data – Rebuilding parity on an array uses the data on the array to create
new parity data, no repair problems with the data.
Verify the parity data – Verify that the data is free of errors.

process scans, rewrites, and scrubs bad data conditions caused by excessive vibration
during drive I/Os, or data degradation caused by Adjacent Track Interference (ATI).
3. Click OK to start the operation.
