You can test your DataKeeper resource hierarchy by initiating a manual switchover. This will simulate a failover of the resource instance from the primary server to the backup server.
You can initiate a manual switchover from the LifeKeeper GUI by selecting Edit, Resource, and InService. For example, an in-service request executed on a backup server causes the DataKeeper resource hierarchy to be taken out-of-service on the primary server and placed in-service on the backup server. At this point, the original backup server is now the primary server and original primary server has now become the backup server.
After the switchover, the state of the DataKeeper resource on the target server is set to “Resyncing” in the LifeKeeper GUI. Once the resynchronization is complete the state will change to “Target”, which is the normal Standby condition.
Note: Manual failover is prevented for DataKeeper resources during resynchronization.
If you execute the Out of Service request, the resource hierarchy is taken out of service without bringing it in service on the other server. The resource can only be brought in service on the same server if it was taken out of service during resynchronization.
