Using Serviceguard Extension for RAC, 10th Edition, April 2013

In this case, Oracle Clusterware quorum and voting disk and RAC database files are stored in raw
logical volumes managed by SLVM or CVM. The management of SLVM or CVM storage for Oracle
Clusterware and database is specified in the package configuration of the respective MNPs.
Use Case 2: Oracle Clusterware storage and database storage in CFS
Figure 16 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.
Use case 3: Database storage in ASM over SLVM
Figure 17 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
