Explanation
LCM (Life Cycle Manager) has a built-in 'Stop Update' button in the Prism Central UI that gracefully halts the upgrade process after the currently running update task completes. This is the safest and officially supported method to pause an in-progress LCM operation without risking cluster instability. Canceling via ecli (A) is not a recommended or supported approach and could leave the cluster in an inconsistent state. Running lcm_task_cleanup.py (B) is a cleanup script for stale tasks, not a live-stop mechanism. Restarting Genesis (C) would disrupt cluster services broadly and is not a targeted way to stop LCM.
