Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

Configuring Primary and Recovery Packages as Modular Packages
In a Continentalclusters configuration, starting with version A.08.00, packages specified as a
primary_package or a recovery_package in a recovery group can be configured as a
modular package. The packages can be created using any modules supplied with and approved
in HP Serviceguard. For example, for the Oracle application, the ECM Toolkit supplied modular
package for Oracle can be used to create the primary and recovery packages in the
Continentalclusters.
Continentalclusters supports the following pre-integrated physical replication solutions: Continuous
Access P9000 or XP, Continuous Access EVA, EMC Symmetrix Remote Data Facility, and 3PAR
Remote Copy. When any of these pre-integrated solutions are used, the corresponding
Continentalclusters specific module must be included to the primary and recovery packages. For
example, while using Continuous Access P9000 or XP replication, the dts/ccxpca module must
be used to create the primary and recovery packages.
NOTE: If none of the above pre-integrated physical replications is used, then it is not required
to include any Continentalclusters specific module.
The following topics are covered in this section:
• Configuring primary and recovery packages as modular packages when using Continuous
Access P9000 or XP
• Configuring primary and recovery packages as modular packages when using Continuous
Access EVA
• Configuring primary and recovery packages as modular packages when using EMC SRDF
• Configuring primary and recovery packages as modular packages using 3PAR Remote Copy
Configuring primary and recovery packages as modular packages when using Continuous Access
P9000 or XP
When using Continuous Access P9000 or XP replication in Continentalclusters, the primary and
recovery packages must be created using the dts/ccxpca module. To use this module, Metrocluster
with Continuous Access for P9000 and XP must be installed on all nodes in the Continentalclusters.
If Metrocluster with Continuous Access for P9000 and XP is not installed on all the nodes, then the
following error message is displayed:
The file <complete_path_to_module_file> does not exist or read/search
permission not set for a component of the path:
No such file or directory /etc/cmcluster/modules/dts/mc.2:4: Could not
find include .......
All parameters that were previously available in the Metrocluster environment file are now configured
from the package configuration file. When the package configuration is applied in the cluster
using the cmapplyconf command, the Metrocluster environment file is automatically generated
in the package directory on all nodes in the cluster.
CAUTION: Do not delete the Metrocluster environment file that is generated in the package
directory. This file is crucial for the startup of the package in a Continentalclusters.
