Every quarter, technicians perform a UPS and generator test at the datacenter. During the test, the diesel generators did not function correctly resulting in a datacenter black out. After the…

A monitoring policy defines how systems are observed for performance and availability, but while monitoring might detect the problem, it doesn't address the procedural failures that led to the incomplete recovery.

A change management policy defines procedures for implementing and reviewing changes to IT systems, including testing, rollback plans, and post-implementation validation. The datacenter blackout during a generator test, the subsequent manual and unverified recovery, and the service outage all point to a lack of adherence to or an inadequacy in the existing change management process for critical infrastructure changes and incident response.

A service level agreement (SLA) policy outlines the expected level of service, but it doesn't dictate the operational procedures or incident response steps required to prevent or recover from service disruptions.

A boot sequence policy would specify the order in which VMs or services should start, but the core issue was the lack of verification after recovery, which falls under broader change management and incident response, not just the boot order itself.
