You may run into a situation where a Prism Central task becomes hung and is not, or will not progress. Thankfully there's a simple fix for that using cli.

  1. Connect to your Prism Central VM, and execute the following ecli task command:
nutanix@PCVM:~$ ecli task.list include_completed=false
Task UUID                             Parent Task UUID                      Component   Sequence-id  Type                  Status

2. Update the status of the task by using the identified UUID. You may also update the task status to succeeded if desirable. 

nutanix@PCVM:~$ ergon_update_task --task_uuid='<Task UUID>' --task_status=aborted

This should update the task status in the prism UI showing the correct status.
