SI-13(4) — Standby Component Installation and Notification
If system component failures are detected: Ensure that the standby components are successfully and transparently installed within {{ insert: param, si-13.04_odp.01 }} ; and {{ insert: param, si-13.04_odp.02 }}.

Supplemental Guidance
Automatic or manual transfer of components from standby to active mode can occur upon the detection of component failures.
Practitioner Notes
Install standby components that can take over automatically when primary components fail, and notify administrators when a failover occurs.
Example 1: Deploy Windows Server Failover Clustering for critical services like SQL Server, file shares, and domain controllers. The standby node takes over within seconds of a primary failure, and the cluster sends email alerts to your operations team about the failover.
Example 2: Configure your firewall in an active/passive HA pair. The standby firewall continuously mirrors the primary's state table. If the primary fails, the standby takes over with no dropped connections. SNMP traps alert your team about the failover event.
