Configuring BCC for Cluster
1 2
Resources
After you have set up the Novell
using Novell Business Continuity Clustering software, you are ready to configure the cluster
resources for BCC. You can enable one or multiple cluster resources in each of the peer clusters for
business continuity that if you want to be able to fail over between peer clusters. For each resource,
you can specify the preferred peer clusters for failover.

12.1.1 LUNs for Cluster Pool Resources

In a business continuity cluster, you should have only one NSS pool for each LUN that can be failed
over to another cluster. This is necessary because in a business continuity cluster, entire LUNs fail
over to other peer clusters. A pool is the entity that fails over to other nodes in a given cluster.
Multiple LUNs can be used as segments in a pool if the storage systems used in the clusters can fail
over groups of LUNs, sometimes called consistency groups. In this case, a given LUN can
contribute space to only one pool.

12.1.2 Volumes for Cluster Pool Resources

A cluster-enabled NSS pool must contain at least one volume before its cluster resource can be
enabled for business continuity. You get an error message if you attempt to enable the resource for
business continuity if its NSS pool does not contain a volume.
