'''Video summary:''' "Signxca DR related training to service team" -- a long (~45+ minute), mixed Hindi/English hands-on training session on the SignXCA disaster-recovery setup, aimed at the service/support team. Opens with the conceptual architecture: the primary datacenter (DC) runs both the eSign and Traditional environments across four oVirt/RHV hosts backed by a shared, partitioned storage array, while the DR site is a smaller, half-capacity mirror (fewer hosts, its own storage) connected to the DC via one-way storage-to-storage replication that gets reversed once a DR drill or real failover ends. A key design point is an L2 network extension between DC and DR, meaning VMs can come up at the DR site with the exact same IPs they had at the DC -- during a real DR event, the DC side is shut down, replication is paused, and the full environment (normally ~200-300 VMs, though DR is provisioned at reduced capacity) is expected to boot at DR unchanged. The session then moves into hands-on DR-drill execution: navigating the oVirt "Disaster Recovery" role, generating the DR configuration file (`dr.conf`) from a template using the manager's API credentials, hostnames, and CA certificate copied from the currently-active site, correcting auto-generated/commented-out fields for the secondary (DR) site, verifying host DNS/hosts-file entries and reachability between manager and target hosts, and applying the resulting Ansible playbook-driven failover. Also covers checking storage/data-domain visibility from the DR-side manager UI and using the `admin@internal` oVirt account for command-line/API operations. The recording includes real troubleshooting back-and-forth (access/OTP issues, a mid-session interruption) rather than a clean scripted demo, consistent with an authentic live training call.
