Scenario: The current XenServer pool master needs to be retired. A Citrix Engineer is preparing to transfer the pool master role to another host. Which command should the engineer run to transition…

xe pool-recover-slaves is used to re-synchronize slave hosts that have lost contact with the master after a master failure, not to transfer the master role.

The xe pool-designate-new-master command is designed for planned, graceful master transitions where the current master is still online and healthy. It instructs the pool to elect the specified host as the new master and coordinates the handover cleanly, which is the correct procedure when retiring a functioning pool master.

xe pool-emergency-reset-master resets the master address across the pool in an emergency where the old master is unreachable, not for a planned transition from a running host.

xe pool-emergency-transition-to-master forces a slave to promote itself to master during an emergency when no master is available, and is not appropriate when the existing master is still in a running state.
