- Select the group -> Right click with the mouse -> Add the resource.
- In resource wizard, select a shared disk DR and click the Next button.
The shared volume set of resource wizard will display the drive characters that can be used to compose the shared disk DR and the existing drive characters that are already configured.
You cannot inquire about information at the remote server. So, you need to enter drive characters and IP addresses on your own.Warning The drive characters to be used as the shared disk DR should be same on the both servers that compose a cluster. Data will be copied to the target node from the source node. The remote server cannot be the source. Be careful when you select the drive character where data exists. If you try to add the existing mirror volume, <mirrored> will be added to the volume letter.
[Figure] Shared Disk DR Resource AddedClick the 'Additional Setup' to define the synch mode and the disk test option.
Info <Sync mode> Once selected, the sync mode cannot be reversed. So, be careful.
Sync mode : Response is slow but there is no data loss involved. Async mode : Relatively faster than the sync mode but it can suffer from data loss.
<Disk test option> Set the disk test command option. For more details on the function, refer to MSDN.
[Figure] Shared Disk DR Additional SettingPress the Finish button after adding the shared disk DR resource, the following warning screen will be displayed.
Check again if it is the correct source server selected.
If not, then click on the 'Cancel' button and set it again.

ArgList Factor | Description | Type | Default | Modification | Note |
ChkDsk | When the volume is mounted, according to the 'Disk Test Options', disk is tested for errors. If it is set to true, and if dirty bits are set to the online volume, the ChkdskArg option will be used to run checkdisk. Before running checkdisk, the mirror copying will be automatically stopped and resynchronization will be performed after finished. | BOOLEAN | false | O |
|
ChkdskArg | When the checkdisk (Chkdsk) option is set to true, the check disk command option is activated. | STRING | /F | O |
|
DirtyBit | It means that dirty bits are set to the target mirror volume. In general, if you need to check the integrity of the target volume, the system will set this. | BOOLEAN | false | X |
|
DriveLetter | The mirror volume is assigned to the drive character. It should be configured to obtain the same value at the source and the target systems. | STRING |
| X |
|
DRState | The mirror status of the mirror volume. It is renewed from an event log. | STRING |
| X |
|
DRType | Determine the mirror synchronization mode. Set it to A or S. ( A - async mode, S - sync mode) * If it is set to asynch mode, data loss can occur. | STRING | A | X |
|
ResyncNeed | It represents the total sum of the blocks requiring re-synchronizing. | INTEGER |
| X |
|
ResyncTotal | It is the total sum of the re-synchronizing blocks. | INTEGER |
| X |
|
SharedSrcIp | It is the IP address used to manage the volume shared between two nodes. | STRING |
| X |
|
SharedSrcRole | It represents the role of the shared volume for each node. | STRING |
| X |
|
TargetDRIp | The IP address used to copy the volume. | IP ADDRESS |
| X |
|
TargetDRLetter | It is the drive character for the DR target volume. | STRING |
| X |
|
TargetDRRole | It represents the role of the shared volume for the target DR node. | STRING |
| X |
|
TotalSpace | It represents the total size of the target mirror volume. | INTEGER |
