The MySQL database resource group typically contains the following resources:
HAStoragePlus resource, which manages database storage
Logical host resource, which provides the address to connect with the MySQL replication user
MySQL database resource, which resides on top of the first two resources to make the database highly available locally
On single-node clusters, the HAStoragePlus resource can be omitted. The creation of the database resource group and its resources is the topic of Oracle Solaris Cluster Data Service for MySQL Guide .
The database resource group and its objects can have different names across the clusters.
