As of I have understood about the f/o and f/b feature is , we are not giving out the detailed steps involved in the Fail-over and Fail-back to the user , but rather we just mention, what this feature is capable of and how should a customer approach, to use this feature. For that , I think this is sufficient in the documentation.
Red Hat Storage 2.0 supports Geo-Replication failover and failback. If the master goes down, you can trigger a failover procedure so that the slave can be replaced as the master. During this time, all I/O operations including writes and reads are done on the slave (now acting as master). When the original master (OM) is back online, you can trigger a failback procedure on the original slave (OS) so that it syncs the delta back to the master.
And then in the note section, we can mention,
Note : "Implementation of f/o and f/b for production mandates a Red Hat Professional Services engagement. Please contact your Red Hat representative for more information." Something like that.
But Documentation already has the detailed steps to execute. I feel we should remove that.
I have added a Warning on engaging Red Hat Professional Services and retained instructions on triggering Failover and Failback based on Sayan's suggestion. The updated documentation is available at: http://documentation-stage.bne.redhat.com/docs/en-US/Red_Hat_Storage/2.0/html/Administration_Guide/ch11s05.html
