Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access for P9000 and XP A.11.00

NOTE: While the Device Group Monitor (DGM) is used, the online package
re-configuration of the DGM parameters is not supported. The online package
re-configuration of the 3DC parameters is supported only for the following:
• AUTO_SVOLPSUS
• AUTO_SVOLPSUE
• AUTO_SVOLPFUS
• AUTO_PSUSSSSWS
• AUTO_PSUEPSUS
• AUTO_NONCURDATA
• AUTO_FENCEDATA_SPLIT
When DGM is not used, the online package re-configuration of all 3DC parameters
is supported.
b. Un-comment the service parameters for the Device Group Monitor and provide a unique
name to the service_name parameter. Do not edit the service_cmd parameter. It is
auto generated. For Example:
service_name mcxpca_dgmonitor
service_cmd "/usr/sbin/DRMonitorXPCADevGrp
${DTS_dts/dts/dts_pkg_dir}/${SG_PACKAGE_NAME}_xpca.env"
service_restart none
service_fail_fast_enabled no
service_halt_timeout 300
If you do not want the package to fail upon device group monitoring failures, you can
set the service_restart to unlimited.
4. Validate the package configuration file.
# cmcheckconf -P pkgName.config
5. Apply the package configuration file.
# cmapplyconf -P pkgName.config
After the modular primary package is created in the primary cluster, if the value of any 3DC
parameter needs to be changed, then edit this package configuration file and re-apply it.
Starting the primary packages in the primary cluster
Ensure all Continuous Access Device groups are paired appropriately according to their 3DC
topology. Start all the primary packages at their DC1 site in the primary cluster, using the cmrunpkg
command.
Installing and configuring the application at the recovery cluster
Install and configure the application in the recovery cluster. The application must be configured at
the recovery cluster using the replicated disks at the recovery cluster.
Configuring Recovery Packages in the Recovery Cluster
A recovery package must be created using Metrocluster 3DC recovery module
dts/recovery_xpca3dc. All 3DC parameters must be configured in the recovery package
configuration file itself. There is no need to edit the Metrocluster environment file. The
