Creating a DataKeeper Resource Hierarchy

If you are creating a DataKeeper resource hierarchy in a Multi-Site Cluster environment, refer to the procedures at the end of this section after you select the Hierarchy Type.

Perform the following on your primary server:

Select Edit > Server > Create Resource Hierarchy

The Create Resource Wizarddialog will appear.

Select the Data Replication option from the drop down list and click Next to continue.
You will be prompted for the following information. When the Back button is active in any of the dialog boxes, you can go back to the previous dialog box. This is helpful should you encounter any error requiring you to correct the previously entered information. You may click Cancel at any time to cancel the entire creation process.

Field	Tips
Switchback Type	You must select intelligent switchback. This means that after a failover to the backup server, an administrator must manually switch the DataKeeper resource back to the primary server. CAUTION: This release of SteelEye DataKeeper does not support Automatic Switchback for DataKeeper resources. Additionally, the Automatic Switchback restriction is applicable for any other LifeKeeper resource sitting on top of a DataKeeper resource.
Server	Select the name of the server where the NetRAID device will be created (typically this is your primary server). All servers in your cluster are included in the drop down list box.
Hierarchy Type	Choose the data replication type you wish to create by selecting one of the following: Replicate New File System Replicate Existing File System DataKeeper Resource
Bitmap File	Select or edit the name of the bitmap file used for intent logging. If you choose None, then an intent log will not be used and every resynchronization will be a full resync instead of a partial resync.
Enable Asynchronous Replication ?	Select Yes to allow this replication resource to support asynchronous replication to target systems. Select No if you will use synchronous replication to all targets. You will be asked later to choose the actual type of replication, asynchronous or synchronous, when the replication resource is extended to each target server. (See Mirroring with SteelEye DataKeeper for a discussion of both replication types.) If you want the replication to any of these targets to be performed asynchronously, you should choose Yes here, even if the replication to other targets will be done synchronously.

The next sequence of dialog boxes depends on which Hierarchy Type you have chosen. While some of the dialog boxes may be the same for each Hierarchy Type, their sequence and the required information may be slightly different. The next three topics take you through the remainder of the Hierarchy creation process.
