Which tool or function can minimize the impact of planned operating system downtime on active workloads?

Integrated Visualization Manager is not a recognized IBM PowerVM feature related to workload migration or minimizing OS downtime impact.

Live Application Mobility is an IBM PowerVM feature that enables active applications and workloads to be moved from one LPAR to another while they continue running. This allows administrators to evacuate workloads before taking an LPAR down for scheduled OS maintenance, preventing service interruption. Unlike Live Partition Mobility, which relocates an entire LPAR between physical servers, Live Application Mobility targets specific workloads within the virtualized environment.

Partition Flexibility Mirror is not a standard IBM PowerVM feature and does not describe a workload migration capability.

Dynamic Hosting Environment is not a standard IBM term for any workload mobility or downtime-mitigation technology.

Micro-Partitioning enables fine-grained CPU resource allocation across LPARs but does not provide any mechanism for migrating workloads away from a partition being taken offline.

Live Partition Mobility moves an entire running LPAR between physical servers to address physical hardware maintenance, not OS-level downtime within a partition.

Shared Storage Pools provide shared virtual storage resources across LPARs but do not facilitate workload migration during planned OS downtime.
