This section can help you effectively manage a business continuity cluster with the Novell

Business Continuity Clustering software. It describes how to migrate cluster resources from one

IMPORTANT: Identity Manager must be configured and running on one node in each peer cluster

before any BCC enabled cluster resource changes are made. Make sure that the Identity Manager

server is part of the cluster and that it is working properly whenever you make BCC configuration

changes to the BCC-enabled cluster resources. For information, see

11.1 Migrating a Cluster Resource to a Peer

Cluster

Although Novell Business Continuity Clustering provides an automatic failover feature that fails

over resources between peer clusters, we recommend that you manually migrate cluster resources

between the peer clusters instead. For information about configuring and using automatic failover

for a business continuity cluster, see

11.1.1 Understanding BCC Resource Migration

A cluster resource can be migrated or failed over to nodes in the same cluster or to nodes in a peer

cluster. Typically, you migrate or fail over locally to another node in the same cluster whenever it

makes sense to do so. If one site fails (all nodes in a given cluster are not functional), you can use

iManager to manually BCC migrate resources to any of the peer clusters. Each resource starts on its

preferred node on the peer cluster where you have BCC migrated the resources.
