For the PROD Oracle RAC database, we created three volume groups:
We created a dedicated ORA_DATA volume group that included DATA volumes, REDO volumes, and FRA volumes and put the TEMP in a separate volume group, ORA_TEMP. This design meets the requirement for a consistent snapshot of all the DATA, REDO, and FRA volumes to enable the creation of a snapshot database based on these volumes. The TEMP volume is not required to be a part of the snapshot.
The following table shows the volumes for the PROD Oracle RAC database:

We created a host group to map these production database volumes to two PROD database servers. As shown in the following figure, this host group consists of two PROD database hosts, R740_92J-21 and R740-92-J19:
Each of the PROD database hosts has four initiators that are based on the HBAs installed on each of the hosts, as shown in the following figure:
