Prerequisites for the disaster recovery process
This runbook assumes that the following is true:
OpenStack Cloud A and OpenStack Cloud B both have an active NetBackup for OpenStack installation with a valid license
OpenStack Cloud A and OpenStack Cloud B have free resources to host additional VMs
OpenStack Cloud A and OpenStack Cloud B have Tenants/Projects available that are the designated restore points for Tenant/Projects of the other side
Access to a user with the admin role permissions on domain level
One of the OpenStack clouds is down/lost
We assume that OpenStack Cloud A is down and the polices are getting restored into OpenStack Cloud B.
In the case of the usage of shared Tenant networks, beyond the floating IP, the following additional requirement is needed: All Tenant Networks, Routers, Ports, Floating IPs, and DNS Zones are created.
