Resource
Tag
Select or enter a unique DataKeeper Resource Tag name for the DataKeeper
resource instance.
Bitmap File
Select the bitmap file entry from the pull down list.
Displayed in the list are all available shared file systems that can be used to
hold the bitmap file. The bitmap file must be placed on a shared device that can
switch between the local nodes in the cluster.
Important: The bitmap file should not reside on a btrfs filesystem. Placing data
replication bitmap files on a btrfs filesystem will result in an "invalid argument"
error when LifeKeeper tries to configure the mirror. The default location for the
bitmap file is under /opt/LifeKeeper. This default location should be
changed if /opt/LifeKeeper resides on a btrfs filesystem.

Click Create to create your DataKeeper device on the local disk or partition.
6. An information box appears and LifeKeeper will verify that you have provided valid data to
create your DataKeeper resource. If LifeKeeper detects a problem, an ERROR will appear in
the information box. If the validation is successful, your resource will be created.
Click Next to continue.
7. An information box appears announcing the successful creation of your DataKeeper resource
device. You must Extend the hierarchy to another server in your cluster to begin data
replication and in order to place it on the backup/target server and under LifeKeeper protection.
Click Continue to extend the resource, or click Cancel if you wish to extend your resource at
another time.
If you click Continue LifeKeeper will launch the Pre-extend Wizard. Refer to Step 2 under
Extending Your Hierarchy for details on how to extend your resource hierarchy to another
server.
