Changing mirror relationship schedules

You can change a schedule that updates mirror relationships for FlexVol volumes and Infinite Volumes if the schedule impacts other backups or updates.

Before you begin

  • You must have created the cluster and Storage Virtual Machine (SVM) peering relationship.

    To know about creating cluster and SVM peering, see the Clustered Data ONTAP System Administration Guide for Cluster Administrators.

About this task

Changing a schedule affects load-sharing mirror copies differently than it does for data-protection mirror copies. If you change a schedule to a load-sharing mirror relationship, Data ONTAP makes the change to the relationships of all the load-sharing mirror copies in the group. Data ONTAP determines the load-sharing mirror group by the SVM and source volume specified by the command. See the Clustered Data ONTAP Logical Storage Management Guide for more information about load-sharing mirror copies.

Steps

  1. Create the new schedule by using the job schedule cron create command.
    Creating a schedule is described in the cron job creation section of the Clustered Data ONTAP System Administration Guide for Cluster Administrators. See the man page for details about the job schedule cron create command.
  2. Change the schedule for a mirror relationship by using the snapmirror modify -schedule command.
    This command must be used from the destination SVM.
    Example

    The following command changes the update schedule used by a data protection mirror relationship for destination volume named "dept_eng_ls1" to a schedule named "dept_eng_mirror_sched":

    vs2::> snapmirror modify -source-path vs1:dept_eng 
    -destination-path vs2:dept_eng_ls1 -schedule dept_eng_mirror_sched
