request system heartbeat-pause set interval <pause-time-in-minutes>
You can view the time remaining in pause interval using the following command.
request system heartbeat-pause show interval

) If you complete vMotion before the pause interval has elapsed, you can end the pause by setting the interval to zero (0).
request system heartbeat-pause set interval 0
