Parameters

3site_consistency_group_name
(Required) Specifies the 3-site remote copy consistency group name that you want to stop data cycling on. This value is a string with a maximum of 10 characters.

Description

This command has no effect on the 2-site consistency group between the two near sites. Data cycling to the far site is stopped immediately. The freeze_time value that is displayed by the ls3sitercconsistgrp command indicates the time of the most recent consistent image available on the auxiliary-far site. Stopping data cycling leaves the 3-site consistency group in a stopped state. This command does not enable user access to data on the auxiliary-far volume. To get an identical image of the near site data on the far site (latest copy), these steps must be completed by the administrator:
  1. Stop the application on the primary site and record the time at which this step is done.
  2. Wait for at least two cycle periods and check the freeze time on the auxiliary-far site. If it is greater than or equal to the time the application is stopped, then the image on the near sites and the auxiliary-far site are identical.
  3. This command does not make the auxiliary-far site default volume accessible to the user. An administrator is expected to access data from the volume by using a FlashCopy from the default volume.

If the state of the 3-site consistency group is 3site_inconsistent, the stop operation immediately stops the 3-site data cycling, restores the auxiliary-far site volumes to a blank state, and the volumes on the auxiliary-far site are unusable (inconsistent).

This command does not stop synchronous replication between near sites. Running this command on an already stopped 3-site consistency group has no effect.

Warning: You must stop the FlashCopy mapping to a non-3-site volume before you delete that volume.
