Hi Codebuilder,

As checked in our environment we have configured extra server role for different servers.
Deployer:- Server Role(Deployment Server,Indexer,KV Store,Search Head,SHC Deployer)
Indexer :- Server Role( Indexer,Search Head,License Maste)
License Master/Deployment Server :- Server Role( Cluster Master,Deployment Server,IndexerLicense, MasterSearch, HeadSHC Deployer)

kindly let me know if the configuration is right on different servers.

[codebuilder]

Your servers should not be assigned any roles they are not performing.

[anupkumar]

will it create problem during upgrade, as we are planning to upgrade from 6.5.0 to 7.3.0.
please suggest if i disable the other roles, in different servers, it will be safe to handle.

That error likely means that your deployer is configured as a license master.

On the web UI for your deployer, go to Settings (black bar) > Monitoring Console > Settings (green bar) > General Setup

On the Actions column click Edit, and remove all roles not associated with your Deployer.

Repeat this on your DMC, just to be safe.
