Symptoms

The ZFSSA cluster is configured to use self replication and its reverse replication in production. 

But when the self replication is reversed, akd assigns 127.0.0.1 as a target, which we do not want to use, and can lead to akd issues.

 

Changes

It is not supported to use 127.0.0.1 for replication.

But it is working for customer since he used a singleton IP.
