Before you can restore a replication link, both systems involved in the link must have the required SSL certificates installed, as described in Configuring SSL for replication.
You don't need to restore a link if both systems involved in the link have the correct link configuration. In this case, you can skip this step of the recovery procedure even though the Restore Link button is active.
To restore a replication link after a system failure:
1.In the top-level menu of the HCP System Management Console for the system where the link configuration still exists, select Services ► Replication.
2.On the replication Links page, click the link you want to restore.
3.On the replication link details page, click Link.
4.If necessary, update the link configuration. You need to do this only if the domain name or IP addresses of the other system have changed.
If the domain name of the other system has not changed, do not replace the displayed IP addresses with the domain name.

Note: After the failure of a system that's part of an erasure coding topology, if the replacement system has a different domain name or different IP addresses from the failed system, you need to reconfigure all the replication links that connect other systems in the topology to the failed system. When reconfiguring the links, ensure that they all connect to the same replacement or rebuilt system. If the links connect to different systems, the erasure coding topology will no longer be functional. |
For instructions on updating the link configuration, see Modifying a replication link.
5.In the replication Link panel, click the Failover tab.
6.In the Failover panel, click Restore Link.

Note: If you don’t see the Restore Link button, wait a few minutes and then redisplay the Replication page. Before the System Management Console can display this button, HCP needs to recognize that the other system is available, has the necessary SSL certificates installed, and isn’t aware of the existing link. |
After you restore a link, the Restore Link button remains active. This state enables you to repeat the restore procedure if the system that failed needs to be rebuilt again before you fail back or begin recovery on the link. Even though the button is still active, you can proceed to the next step in the recovery procedure.
