The documentation on setting up disaster recovery is in the following link
Disaster Recovery - CA Performance Management - 3.6 - CA Technologies Documentation
But this requires that passwordless SSH is setup between all nodes in the primary site, with all nodes in the recovery site
In addition, it is required to have port 50000 open for rsync, from all nodes in the primary site, to all nodes in the recovery site; and visa versa. I have verified this with Vertica.
