Reversing Replication Back to the Production Site (CLI)

Language:

After all changes have been replicated from the recovery site to the production site, reverse replication again to restore the original replication relationship between the source appliance and replication target.

From the replication target, navigate to shares replication packages and list the packages.

loader:> shares replication packages
loader:shares replication packages> list

ID          STATE DATA TIMESTAMP      SOURCE       DATASET
package-002 idle  2015-10-02 19:26:37 hostsource   berries
package-001 idle  2015-10-02 19:26:10 hostsource   berries
package-004 idle  2015-10-02 20:53:51 hostsource   berries/blackberry
package-003 recv  2015-10-02 20:59:52 hostsource   cherries/maraschino

The package with the most recent data timestamp for this dataset is the one with the most recent, up-to-date data for the corresponding source dataset.

Select the replication package you want to reverse.

loader:shares replication packages> select package-002

Enter pkgreverse.

host-prod:shares replication package-002> pkgreverse

(Optional) Set a new project name and enable the action using the following commands:
```
host-prod:shares replication package-002 pkgreverse> set new_project_name=new-kmm3
              new_project_name = new-kmm3
host-prod:shares replication package-002 pkgreverse> set enable_action_upon_reversal=true
   enable_action_upon_reversal = true
```
Note - The project name must be unique on the appliance where the reverse operation is performed. If a project with the same name exists on the appliance at the production site, the reverse operation will fail.

Enter show to confirm the properties, and then enter commit:

host-prod:shares replication package-002 pkgreverse> show
Properties:
              new_project_name = new-kmm3
   enable_action_upon_reversal = true

host-prod:shares replication package-002 pkgreverse> commit
This action will move the contents of this package to a new local project
configured to replicate back to the source. Any data or metadata changes made
on the source since the last successful update will be lost when the new
project is replicated back to the source. If replication actions on the source
are not disabled, future updates to this package will fail.

Depending on the protocol used, remap (SMB clients) or remount (NFS clients) shares to the appliance at the production site.
