HP Serviceguard Extension for RAC (SGeRAC) manual Use case 3 Database storage in ASM over Slvm

Use Case 2: Oracle Clusterware storage and database storage in CFS

Figure 14 Use Case 2 Setup

In this case, Oracle Clusterware quorum and registry device data is stored in files in a CFS. Oracle database files are also stored in a CFS.

For each CFS used by Oracle Clusterware for its quorum and registry device data, there will be a dependency configured from the Oracle Clusterware MNP to the mount point MNP corresponding to that CFS. The mount point MNP has a dependency on the CFS system MNP (SMNP).

Similarly, for each CFS used by the RAC database for database files, there will be a dependency configured from the RAC database MNP to the mount point MNP corresponding to that CFS. Only the Oracle Clusterware and RAC DB Instance MNPs, and their dependencies, in this use case are to be configured and managed as described in this chapter. The rest of the multi-node packages shown for this use case are created via the CFS subsystem. Configuration and administration procedures for these MNPs are specified in the SGeRAC user guide.

Figure 15 Use Case 3 Setup

The above diagram can be considered as one use case. Here we have one Oracle Clusterware MNP, three ASMDG MNP, and four RAC database MNP. All the ASMDG MNPs should be made
