This section only describes the required changes to the package
control script to support the cascading failover configuration.
To create a recovery package on the recovery cluster, the reader
should follow the procedure in “Setting up a Recovery Package on the Recovery
Cluster”. There
is a slight difference from the normal ContinentalClusters configuration
in customizing the recovery package control script <bk_package_name>.cntl:
Leave commented the PKGR1SYMGRP variable.
The PKGR2SYMGRP variable should be set to the Symmetrix device group
name that was defined in the recovery Symmetrix.
The elements of the R2HOST array variable should be set to the hostnames
of the systems that connect to the recovery Symmetrix
The CLUSTER_TYPE variable should be set to "continental"
Before running cmapplyconf command for the recovery cluster, make sure to split
the SRDF logical links, between the secondary Symmetrix and the
recovery Symmetrix, for the disks associated with the application
package. Run the following command on a node that connects to the
primary Symmetrix# symrdf -g <prisymdevgrpname> split -rbcv -v
