Manual Creation of a Mirror in WSFC

!Before creating an Empty Role, verify that your mirror(s) are Highly Available by confirming that they are listed in the Failover Cluster Manager\Storage Disk as Available Storage.

If you do NOT see your mirror(s) listed as Available Storage, they are NOT Highly Available –

Return to an elevated command prompt (on the Source) and proceed with the following 3 steps:

1. cd %extmirrbase% (Shortcut to the DataKeeper Directory)

2. emcmd . registerclustervolume (drive letter)

3. Your output should reflect “Status = 0“

Once mirror(s) are highly available using the steps above (if needed), return to Failover Cluster Manager\Storage\Disk. The mirror(s) should be listed as “Available Storage”

Now you’re in a position to Create an Empty Role.

1. Launch Failover Cluster Manager

2. Right click on Roles and select “Create Empty Role”

- A default role called “New Role” will be created

3. Rename “New Role” to “DataKeeper Service”

4. Return to Storage\Disks…Available Storage

5. Right click the Volume/Available Storage, More Actions, Assign to Another Role…

6. Select the Role that you’ve created in Step 3 or in this instance, “DataKeeper Service”

Note: The DataKeeper Mirror(s) has been assigned to the role you have created, thus the DataKeeper Volume(s) are now Highly Available.

This can be tested by:

1. Right clicking the role/DataKeeper Service\Move\Select Node…

2. Select any other servers/nodes available in your cluster, then OK.

Perform another Move to ensure the Role and its related resources/DataKeeper, switch back successfully.
