Figure 3. Use Case 2 setup
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 document. 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.

How to create a Serviceguard Extension for RAC modular package
In SGeRAC A.11.19, SGeRAC introduces modular package format. With this feature, the user can
use the single SGeRAC package interface to manage SGeRAC Toolkit to simplify Toolkit
management. Please refer to the SGeRAC README for detail.
How Serviceguard Extension for RAC Toolkit maintenance mode works
As of SGeRAC A.11.18, SGeRAC Toolkit supports the maintenance mode, so the user can maintain
Oracle Clusterware and Oracle database instance without halting Oracle Clusterware MNP and
Oracle database instance MNP. To enable this feature, the MAINTENANCE_FLAG for both the
Oracle Clusterware MNP and Oracle database instance MNP must be set to yes. The
MAINTENANCE_FLAG parameter is specified in the respective toolkit configuration files.
Use Case 1: Performing maintenance with Oracle Clusterware
Both the Oracle Clusterware MNP and the Oracle database instance MNP go into maintenance
mode.
