Group should be configured as IP address dependent on network interface card, ORACLE server dependent on disk where database is stored, ORACLE listener dependent on ORACLE server to provide proper service.
IP address cannot be assigned without network interface card, process related to ORACLE can be bring online after disk completed online. If there is more than a group defined on a cluster, one group will failover without affecting the other groups.
