Process for Very Large NTP Offset

If the NTP offset is very large:

  1. To verify the NTP server is configured correctly and works on the MPE/MRA device, use ntpq-pn.
  2. If the MPE device has the active role in the cluster, please run a switch over of this cluster to make this device use standby role.
  3. Perform these commands in order:
    1. service qp_procmgr stop
    2. service comcol stop
    3. service ntpd stop
    4. service ntpdate restart
    5. Wait one minute for the sync between device and the NTP server to complete.
    6. service ntpd start
    7. date
    8. wclock
    9. ntpq -pn
    10. Check sync is done and the time is accurate for the server time and BIOS clock.
    11. service comcol start
    12. service qp_procmgr start
  4. Monitor the system for several minutes and then verify the system status is functioning normally, and that all the alarms are cleared.
