1. Re: What happens when a domain controller goes down?
nadirx Feb 4, 2016 2:13 AM (in response to udit-mishra-5113a21a)The DC does not affect operations on the cluster. It can be safely restarted without interrupting availability. Obviously, during its downtime, no configuration changes can be made.

udit-mishra-5113a21a Feb 4, 2016 2:20 AM (in response to nadirx)Agree, and when it is up, if I make configuration changes, does it need a restart? Lets say, I have changed the number of Owners of a cache in domain.xml, do I need a restart in that case?

nadirx Feb 4, 2016 2:33 AM (in response to udit-mishra-5113a21a)Changes to the domain configuration should be made to the CLI instead of modifying directly the XML, if the domain is running.
You only need to restart the resource which is affected by your change: since number of owners is per-cache, you just need to restart that cache.

udit-mishra-5113a21a Feb 8, 2016 1:19 AM (in response to udit-mishra-5113a21a)Hello nadirx , I would like to have one more clarification. Lets say my cluster was running perfectly and because of some reasons, assume that the entire cluster went down. Now, upon restarting, suppose everything gets restarted, just the machine which was acting as a DC could not get restarted, so will Host controllers will be able to start and have that configuration? Will they be able to form topology? If yes, then wonderful. If no, then can I have multiple DCs just for the backup? What if both the DCs are up, will it lead to any confliction?
