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

Installing and configuring a redundant copy of the application in the
recovery site
Install the application at the secondary site and configure it to use the same replicated disks as in
the previous step. Then, configure the application and its resources as a Serviceguard package.
Configuring the Continentalclusters primary and recovery packages
The packages can be created using any modules supported by HP Serviceguard for Linux .
For example, for Oracle application, the Serviceguard Oracle toolkit for Linux can be used to
create the primary and recovery packages in Continentalclusters.
Continentalclusters for Linux supports the following pre-integrated physical replication solutions:
• Continuous Access XP P9000
• Continuous Access EVA 6000
• 3PAR Remote Copy
When any of these pre-integrated solutions are used, the corresponding Continentalclusters specific
module must be included in 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 pre-integrated physical replications listed here are used, it is not required
to include any Continentalclusters specific module.
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 XP P9000 for Linux must be installed on all the nodes in the
Continentalclusters.
To configure the primary and recovery packages as modular packages using Continuous Access
P9000 and XP with Continentalclusters for Linux:
1. Run the following command to create package configuration file:
# cmmakepkg –m dts/ccxpca temp.config
NOTE: Continentalclusters is usually used with applications such as Apache. So, the
application toolkit module must also be included when Continentalclusters is used in conjunction
with an application.
For Example, when Continentalclusters is used in conjunction with the Apache toolkit, the
Apache toolkit module and other required modules must also be included with the
Continentalcluster module. Run the following command:
# cmmakepkg –m dts/ccxpca –m sg/filesystem -m sg/package_ip -m
tkit/apache/apache temp.config
2. Edit the following attributes in the temp.config file:
• dts/xpca/dts_pkg_dir
This is the package directory for this modular package. This value must be unique for all
packages.
