What happens if the reorganization process is required for a host in a scale-out landscape?

In a scale-out landscape, when the reorganization process is needed for a host, it indicates that the storage and resources of that particular host need to be optimized for performance or manageability reasons. In this situation, the host cannot be removed because it is crucial for maintaining the system's availability and performance during the reorganization.

When reorganization is underway, it often involves redistributing load or reorganizing data across the nodes in the landscape. Removing a host during this process could lead to imbalances or resource contention that could affect the performance of the entire landscape. Therefore, to ensure data integrity and continuity, the host remains active and fully engaged until the reorganization is complete.

This context clarifies why the other options do not align with the principles of managing a scale-out landscape. A flagged active state, migration initiation, or the need for additional resources doesn't accurately capture the protocol that requires the host to stay in operation during the reorganization process.
