<Commands for RDR Virtual Disk>
Verify RDR Virtual Disk
Whether the synchronization by RDR is performed normally can be checked.
1.Start RDR Utility and
2.In the [Success] dialog box, click [OK].
The progress of verification can be viewed using RDR Utility.
| Verifying | Verification completed | |
[Status] of RDR Virtual Disk x | Verify x percent | None | |
(x=1,2,3) | (x=0, 10, 20, …, 90) | ||

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.
1.Start RDR Utility,
2.When a dialog box appears, select Low, Normal or High (a default is Normal) and click [OK].
3.In the [Success] dialog box, click [OK].
Set RDR LUN Load Balancing
On or off of load balancing can be specified.
When the load balancing is on (default), the read process is performed alternately from two physical disks forming the RDR Virtual Disk to improve performance. When it is off, the read process is performed from the physical disk specified as Active RDR Disk.
1.Start RDR Utility,
2.When a dialog box appears, select On or Off (a default is On) and click [OK].
