Which of the following is a requirement for a concurrent firmware update on a Power Systems server?

Concurrent firmware updates can be applied to fix packs and service packs within an existing release level, not exclusively when moving to a new major release.

A redundant FSP improves resiliency but is not listed as a prerequisite for performing a concurrent firmware update on Power Systems.

The HMC (Hardware Management Console) is a mandatory prerequisite for concurrent firmware updates because it provides the orchestration layer that coordinates the update across the Flexible Service Processor while keeping the system operational. The HMC communicates directly with the FSP to stage and activate firmware without requiring a system power cycle. Without HMC management, the concurrent update workflow cannot be initiated.

Assigning all system resources to a single primary partition is not a requirement and would conflict with normal multi-LPAR operations during the update.
