Stopping replication on an auxiliary-far site for maintenance

Edit online

Before you can complete maintenance on a system at the auxiliary-far site in a 3-site configuration, you must stop replication. After the maintenance tasks are complete, you can restart replication in the 3-site configuration.

When you are completing system maintenance, such as replacing hardware, you can use the management GUI or the command-line interface to stop and restart replication.

Using the management GUI

To stop replication in the management GUI, complete these steps:
  1. In the management GUI, select Copy Services > Remote Copy.
  2. On the 3-Site Partnership page, select a 3-site consistency group to open the details page for the group.
  3. Select Actions > Stop Group.
  4. Click Confirm.
  5. When the process completes, verify that graphic for the overall 3-site consistency group shows that asynchronous copy as stopped.
  6. Repeat these steps for all of the 3-site consistency groups in the 3-site partnership.

After you verify that all the 3-site consistency groups are stopped, complete the system maintenance tasks on the system. When the system maintenance tasks are complete, use the management GUI to restart replication on the 3-site consistency groups.

To start 3-site consistency groups, complete these steps:
  1. In the management GUI, select Copy Services > Remote Copy.
  2. On the details page for the 3-site partnership, select a 3-site consistency group to open the details page for the group.
  3. Select Actions > Start Group.
  4. Click Start.

Using the command-line interface

To complete system maintenance on a system on the auxiliary-far site in the command-line interface, complete these steps:

  1. Enter the stop3sitercconsistgrp command to stop replication.
    [root@ORCH-HOST cli]# stop3sitercconsistgrp CG0
[root@ORCH-HOST cli]# ls3sitercconsistgrp
name state            primary periodic_copy_source sync_copy_state         periodic_copy_state freeze_time cycle_period   status
CG0  stopped          AuXNear AuXNear              consistent_synchronized idling                        0 350            online
  2. Complete the maintenance operations on the auxiliary-far site.
  3. Enter the start3sitercconsistgrp command after maintenance of the auxiliary-far site is complete. 
    [root@ORCH-HOST cli]# start3sitercconsistgrp CG0
[root@ORCH-HOST cli]# ls3sitercconsistgrp
name state            primary periodic_copy_source sync_copy_state         periodic_copy_state freeze_time cycle_period    status
CG0 3site_consistent AuXNear AuXNear              consistent_synchronized stopped                       0 350              online
