Hi there,

i run into a problem with the new Distributed Management Console. When i change to the Ditributed Mode in the Setup view, i get the following Error Message:

Duplicate instance name. Ensure each
instance has a unique instance (host)
name.

Instance (host)--------Instance (serverName)----------Machine

steve.xxxx.de----------bill.xxxx.de--------------------------bill.xxxx.de

steve.xxxx.de----------mike.xxxx.de--------------------------mike.xxxx.de

So steve is the ClusterMaster and the two Nodes are bill and mike. I have no idea where my mistake is. Hope anyone can give me a hint.

Thanks
Regards, Sven

Make sure both server name and host have unique values (looks like you have two instances with the same host value).

From documentation:

"Make sure that each instance in the deployment (each search head, license master, and so on) has a unique server.conf serverName value and inputs.conf host value."

the 'serverName's all need to be different, as well as the GUID (in splunk/etc/instance.cfg)

It looks like both of your "bill" and "mike" instances have the same host value in inputs.conf ("steve.xxxx.de). Those have to be unique as well.
