Linking a reinstalled cluster back to its historical data

No historical data is available for a cluster after reinstalling the cluster connector because reinstallation assigns a new identifier to the cluster. Reinstalling the cluster connector unlinks all historical data from the cluster because the management server identifies the cluster as new. This task enables you to link the cluster back to its historical data.

  Note   This procedure assumes that the cluster connector has already been uninstalled and then reinstalled on the same cluster. If this has occurred, the console displays two clusters of the same name, one in an unknown state and one in an online state.

 To link a cluster back to the appropriate historical data

1. Change the value of the ClusterID attribute of the new CMC_ClusterConfig resource (CMC service group) to the original Cluster ID value.
2. Restart the CMC service group.
3. View all clusters in the enterprise or all clusters in the parent site of the old cluster and then delete the old cluster. Use the Remove Cluster task on the Configuration task menu.

   This action relinks the new instance of this cluster its historical data.
