Jaromir Hamala commented on WFLY-818:
-------------------------------------

I'm afraid that this issue effectively makes DC to be a Single Point of Failure. You have these options: 
1. starting the HC with --cached-dc, but it effectively downgrades it to a standalone mode as is never attempts to contact DC
2. do not use the --cached-dc, but than you HC will fail to start if DC is not available 

Given there is no guide how to make DC highly available, it's a very unfortunate situation and possible a showstopper for deploying JBoss.

> When a slave host is started with --cached-dc option it won't register to Domain Controller although it's available. domain.sh help says "If this host is not the Domain Controller and cannot contact the Domain Controller at boot, boot using a locally cached copy of the domain configuration (see --backup)" and this is not really happening because slave host never contact to DC with --cached-dc
