Using Serviceguard Extension for RAC, 6th Edition, April 2008

• Storage Activation (CFS)
When the Oracle Cluster Software required storage is configured on a Cluster File
System (CFS), the Serviceguard package should be configured to depend on the
CFS multi-node package through package dependency. With package dependency,
the Serviceguard package that starts Oracle Cluster Software will not run until its
dependent CFS multi-node package is up and will halt before the CFS multi-node
package is halted.
Setup dependency conditions in Serviceguard package configuration file (SAMPLE).
DEPENDENCY_NAME mp1
DEPENDENCY_CONDITION SG-CFS-MP-1=UP
DEPENDENCY_LOCATION SAME_NODE
DEPENDENCY_NAME mp2
DEPENDENCY_CONDITION SG-CFS-MP-2=UP
DEPENDENCY_LOCATION SAME_NODE
DEPENDENCY_NAME mp3
DEPENDENCY_CONDITION SG-CFS-MP-3=UP
DEPENDENCY_LOCATION SAME_NODE
• Starting and Stopping Oracle Cluster Software
In the Serviceguard package control script, configure the Oracle Cluster Software
start in the customer_defined_run_cmds function
For 10g 10.1.0.04 or later:
/sbin/init.d/init.crs start
For 10g 10.2.0.01 or later:
<CRS HOME>/bin/crsctl start crs
In the Serviceguard package control script, configure the Oracle Cluster Software
stop in the customer_defined_halt_cmds function.
For 10g 10.1.0.04 or later:
/sbin/init.d/init.crs stop
For 10g 10.2.0.01 or later:
<CRS HOME>/bin/crsctl stop crs
When stopping Oracle Cluster Software in a Serviceguard package, it may be
necessary to verify that the Oracle processes have stopped and exited before
deactivating storage or halting CFS multi-node package. The verification can be
done with a script that loops and checks for the successful stop message in the
Oracle Cluster Software logs or the existences of Oracle processes that needed to
be stopped, specifically the CSS daemon (ocssd.bin). For example, this script
could be called by the Serviceguard package control script after the command to
halt Oracle Cluster Software and before storage deactivation.
