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

Halting the Complex Workload in the Primary Cluster
You need to first halt the complex workload stack on the node in the primary cluster using the
cmhaltpkg command.
Configuring the Site Controller Package in the Primary Cluster
Complete the following procedure on a node in the primary cluster to configure the Site Controller
Package:
1. Create a Site Controller Package configuration file using the dts/sc and array-specific module
as shown below.
For example, when using Continuous Access P9000 or XP, the command is:
cmmakepkg -m dts/sc –m dts/ccxpca cw_sc.config
When using Continuous Access EVA, the command is:
cmmakepkg -m dts/sc –m dts/cccaeva cw_sc.config
When using EMC SRDF, the command is:
cmmakepkg -m dts/sc –m dts/ccsrdf cw_sc.config
2. Edit the cw_sc.config file and specify the following:
• Name for the package_name attribute
package_name <site_controller_package_name>
• Names of the nodes explicitly using the node_name attribute.
• The Site Controller Package directory for the dts/dts/dts_pkg_dir attribute.
dts/dts/dts_pkg_dir /etc/cmcluster/<site_controller_package_name>
This is the package directory for this Site Controller Package. The Metrocluster environment
file is automatically generated for this package in this directory.
• Specify a name for the log file.
script_log_file <log_file_name>
• Specify the site without any packages.
Do not specify any packages using the critical_package or managed_package
attributes.
site <site name>
• Edit the array specific parameters. For configuring these parameters, see the following
sections based on the type of the array used in your environment.
When using Continuous Access P9000 or XP, see “Configuring primary and recovery
packages as modular packages when using Continuous Access P9000 or XP” (page 67).
When using Continuous Access EVA, see “Configuring primary and recovery packages
as modular packages when using Continuous Access EVA” (page 69).
When using EMC SRDF, see “Configuring primary and recovery packages as modular
packages when using EMC SRDF” (page 71).
3. Apply the Site Controller Package configuration file in the cluster.
# cmapplyconf -P cw_sc.config
IMPORTANT: Ensure there are no packages configured with the critical_package or
managed_package attributes in the Site Controller Package configuration file. These attributes
must be configured only after configuring the Site Safety Latch dependencies. For information on
configuring these dependencies, see “Configuring the Site Safety Latch Dependencies” (page 379).
