Which removal statuses allow you to remove a host from an SAP HANA scale-out landscape?

The correct answer is that the removal status "Reorg not required" allows you to remove a host from an SAP HANA scale-out landscape. This status indicates that the system has checked the host and determined that no reorganization of data is needed before the removal process can occur. Essentially, the database is in a healthy state, and there are no dependencies or data fragments that would prevent the removal of the host.

In the context of managing an SAP HANA scale-out landscape, ensuring that the host can be removed without requiring additional data reorganization is crucial for maintaining system performance and availability. It allows for a smooth and efficient process of removing the host without introducing potential downtime or complications associated with data handling.

The other statuses would not permit a host to be removed due to various reasons. For instance, if a status indicates that a reorganization is required or is currently happening, the removal would be prevented until those processes are completed to ensure data integrity.
