  • ONTAP 9
  • Snapmirror

Answer

  • Yes.
  • Updating the time zone on either the source or destination cluster might affect how the job schedules work.
  • For instance,  snapshots on the source might now be created after the scheduled Snapmirror update, causing the snapshots not to be replicated when expected.
  • The time on the source and destination is important because this determines the timestamps on the file system and snapshots. 
    • If time is configured incorrectly, timestamps will be inaccurate.
  • Review when snapshots are created on the source versus the Snapmirror schedules to ensure replication will continue to work as desired.
