Recovering from an active-periodic link failure

Edit online

To recover from an active-periodic link failure, you enter CLI commands to verify the state of the consistency group and recover from the link failure.

Verify that the 050993 3-site consistency group is now in STOPPED State notification is received. To view the event notification, see Informational events.

Enter the ls3sitercconsistgrp command to verify the state of the consistency group.

In the resulting output, the state of the consistency group is stopped.

[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            active_link_offline

To complete the link failure recovery, use one of the following options:
- Option 1 is to switch the periodic replication source. To switch the periodic replication source, complete the following steps:
  1. Enter the ch3sitercconsistgrp -periodicsrc command to switch the periodic replication source.
```
[root@ORCH-HOST cli]# ch3sitercconsistgrp -periodicsrc Master CG0
```
  2. Restore the link and enter the ch3sitercconsistgrp -periodicsrc command to switch the active periodic replication source back to the original link.
```
[root@ORCH-HOST cli]# ch3sitercconsistgrp -periodicsrc AuxNear CG0
```
- Option 2 is to restore the failed link and data cycling automatically restarts.
