Configuring Cluster Resource Groups
Manage cluster-wide resources using Cluster Resource Groups (CRGs).
A CRG manages resources within an IBM® i high availability environment. Users can perform many cluster management functions through tasks that access CRGs. Each CRG has a recovery domain that defines which cluster nodes a cluster resource represented by the CRG can be accessed.
There are 3 CRG types commonly used in high availability environments: device (used mostly for external storage), data (for logical replication), and application (often used with logical replication to start applications).
