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 the section called “Setting
up a Recovery Package on the Recovery Cluster”. There is a slight difference
from the normal Continentalclusters configuration in customizing
the recovery package environment file <bk_package_name>_srdf.env
The PKGR2SYMGRP variable should be set to the Symmetrix device group
name that was defined in the recovery Symmetrix.
The DEVICE_GROUP variable should be set to the Symmetrix device group
name that was defined in the recovery Symmetrix
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
