Refer to the standard Serviceguard manual Managing Serviceguard to
learn about creating and editing a cluster configuration file and how to
apply it to initialize a cluster with cmquerycl(1m) and
cmapplyconf(1m). The following section assumes that a cluster is up
and running on the intended primary node and all failover nodes.
Logon as root on the primary host.
IS400 Installation Step:
Create a Serviceguard package directory. This directory will be used by
all packages that belong to the SAP System with a specific SAP System
ID <SID>.
mkdir -p /etc/cmcluster/<SID>
IS410 Installation Step:
The swinstall process copied relevant files to a staging area at
/opt/cmcluster/sap for reference.
The following files need to be copied from the repository to the SAP
package directory:
cp /opt/cmcluster/sap/sap.functions \
/etc/cmcluster/sap.functions
cp /opt/cmcluster/sap/SID/sap.config \
/etc/cmcluster/<SID>/sap.config
cp /opt/cmcluster/sap/SID/customer.functions \
