Unfortunately upstream doc is not up to date with failover and
failback commands.

But you can use downstream doc :
https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html-single/Administration_Guide/index.html#sect-Disaster_Recovery

These steps should work fine for you.

We will try to update upstream doc as early as possible.

Thanks,
Bipin Kunal
