Creating a DataKeeper Volume Resource in WSFC

Automatic Creation of a Mirror in WSFC

  1. Use the SteelEye DataKeeper GUI to configure a mirror.

  2. At the completion of the mirror creation operation, the following dialog box will pop up which will allow you to automatically add the mirror as a DataKeeper volume resource into WSFC.

If Yes is selected, then the DataKeeper mirror will be added as a DataKeeper volume resource to "Available Storage" in WSFC. However, if No is selected or an error is encountered, follow the steps in the section “Manual Creation of a Mirror in WSFC”, to create the mirror manually.

Whether the mirror is created automatically or manually, the DataKeeper volume resource(s) is placed in "Available Storage." The DataKeeper volume resource(s) can now be utilized just as if it were a physical disk resource. While clustering some applications (SQL for example), the DataKeeper volume resource is recognized and treated exactly the same as a physical disk resource. This means that during the cluster create process, the DataKeeper volume resource will be pulled automatically into the cluster resource and the dependencies will be created automatically. Other applications, notably the Hyper-V “Virtual Machine” resource, are hard-coded to look for a physical disk resource and will not automatically pull the DataKeeper resource into the cluster configuration. In these circumstances, the DataKeeper volume resource can be easily added to the cluster resource and the dependencies can be created manually through the WSFC GUI.

Use the DataKeeper GUI to monitor the mirroring states. It provides more information than the Failover Cluster manager UI.
