TIPS:

The verification process is automatically performed every 720 minutes (12 hours). The time required for verification depends on the disk size and load.

Set Resync Priority

Priority of synchronization can be specified for disk mirroring by RDR.

By changing the priority, I/O load during synchronization can be reduced.
