Building Disaster Recovery Serviceguard Solutions Using Continentalclusters for Linux B.01.00.00

• DC2_RC_VOLUME_GROUP
The Remote Copy volume group name configured on the HP 3PAR storage system, which
is located in Data Center 2, containing the disks used by the application.
• DC1_RC_TARGET_FOR_DC2
The target name associated with the Remote Copy volume group on data center 1 for
the HP 3PAR storage system in Data Center 2.
• DC2_RC_TARGET_FOR_DC1
The target name associated with the Remote Copy volume group on data center 2 for
the HP 3PAR storage system in Data Center 1.
• RESYNC_WAIT_TIMEOUT
The timeout, in minutes, to wait for completion of the Remote Copy volume group
resynchronization.
• AUTO_NONCURDATA
Parameter used to decide whether package can start up with non current data or not.
3. Validate the package configuration file.
# cmcheckconf -P pkgName.config
4. Apply the package configuration file.
# cmapplyconf -P pkgName.config
Configuring the monitor package
The template file for creating a monitor package ccmonpkg is available in the /opt/cmconcl/
scripts directory. This package configuration file includes the Continentalclusters monitoring
daemon /opt/cmconcl/bin/cmclsentryd as a pre-configured service.
To configure the monitoring daemon as a modular package:
NOTE: The file /etc/cmcluster.conf contains the mappings that resolve symbolic references
to $SGCONF, $SGROOT, $SGLBIN, etc. used in the pathnames in the following subsections. If
the Serviceguard variables are not defined on your system, then include the file /etc/
cmcluster.conf in your login profile for the root user. For more information on these parameters,
see Understanding the Location of Serviceguard Files and Enabling Serviceguard Command Access
in Managing Serviceguard for Linux A.11.20.10 available at http://www.hp.com/go/
linux-serviceguard-docs .
1. On any node in the monitoring cluster, create a directory to store the configuration file of the
monitor package.
For Example:
# mkdir $SGCONF/ccmonpkg
NOTE: It is required to create a monitor package ccmonpkg only at recovery cluster
2. Copy the modular package template file, /opt/cmconcl/scripts/
ccmonpkg_modular.config to the directory created in step 1.
# cp /opt/cmconcl/scripts/ccmonpkg_modular.config
/$SGCONF/ccmonpkg/ccmonpkg.conf
3. Skip this step if you are not using the Disaster Recovery rehearsal feature.
For more information about Disaster Recovery rehearsal feature, see “Performing Disaster
Recovery rehearsal in Continentalclusters” (page 34).
