Configuring primary and recovery packages as modular packages using 3PAR Remote Copy
When using HP 3PAR Remote Copy in Continentalclusters, the primary and recovery packages
must be created using the dts/cc3parrc module. To use this module, Metrocluster with 3PAR Remote
Copy must be installed on all nodes in the Continentalclusters.
To configure primary and recovery packages in Continentalclusters when using 3PAR Remote Copy
:
1. Run the following command to create a modular primary or recovery package configuration
file using the Continentalclusters module dts/cc3parrc.
# cmmakepkg –m dts/cc3parrc pkgName.config
2. Edit the following attributes in the pkgName.config file:
• DTS_PKG_DIR
• DC1_NODE_LIST
• DC2_NODE_LIST
• DC1_STORAGE_SYSTEM_NAME
• DC2_STORAGE_SYSTEM_NAME
• DC1_STORAGE_SYSTEM_USER
• DC2_STORAGE_SYSTEM_USER
• DC1_RC_VOLUME_GROUP
• DC2_RC_VOLUME_GROUP
• DC1_RC_TARGET_FOR_DC2
• DC2_RC_TARGET_FOR_DC1
• RESYNC_WAIT_TIMEOUT
• AUTO_NONCURDATA
For more information on these attributes, see “Configuring Modular Packages” (page
322).
3. Validate the package configuration file.
# cmcheckconf -P pkgName.config
4. Apply the package configuration file.
# cmapplyconf -P pkgName.config
NOTE: If the value of any parameter needs to be changed, then edit this package
configuration file and re-apply it.
Configuring Continentalclusters Data Sender and Data Receiver Packages as Modular Packages
Data sender and data receiver packages are configured in Continentalclusters recovery groups
using custom integration with logical replication technologies. These packages can be configured
using the HP Serviceguard modules. No special Continentalclusters modules are required to
configure these packages as modular packages.
Configuring Continentalclusters Rehearsal packages as Modular Packages
With Continentalclusters version A.08.00, packages specified as rehearsal packages in recovery
groups can be configured as modular packages. These packages normally use all the modules
that are used to create the recovery package. However, when using any of the pre-integrated
physical replication solutions, the replication technology specific Continentalclusters module must
not be included.
