Other functions of RDR Utility
Clearing MTBF value
When a failure occurs to a disk, the mean time between failures (MTBF) is counted and the value is
saved. In RDR Utility, the value is displayed at [MTBF: Current] and [MtbfThresholdStatus].
These MTBF values can be cleared by the [Clear MTBF] command.
1.
Start [RDR Utility] and right-click a target disk on the tree in the left frame, and click [Clear
MTBF].
2.
In the [Success] dialog box, click [OK].
Performing resynchronization
If disk synchronization by RDR is broken due to causes including a failure, resynchronize disks by
following either of the procedures below:
[Resynchronization by specifying a disk]
Resynchronize the disk where a command is executed from the disk of the paired slot.
1.
Start [RDR Utility] and right-click a target disk in the left frame and click [Resynchronize
This Disk].
2.
In the [Success] dialog box, click [OK].
3.
The [Op State: State] of the disk becomes [Syncing] and resynchronization starts.
