ok, this docs are goob, but not all

after many tries:

curl -s -X POST http://..:8001/routes/.../plugins \

--data config.scopes_required=... | python -mjson.tool

it's a good idea replace ... with the rights words ;-) 

SOLVED

I create :

/etc/iscagent/iscagent.conf

application_server.port=2188
mirroring.console_logging_enabled=true
logging.minimum_severity=1

privileges.user=root

systemctl restart iscagent
 

After that file /var/log/iscagent_console.log, no more empty file.

no more errors after that

Is so confused, after many documentation reviews and some probably network problems resolved,  error still alive

context

2 new server iris

1 arbiter

4 IP addresss

/etc/hosts fixed with all ip definitions :

serverpri X.X.X.67
serversec X.X.X.65
servervip X.X.X.85
serverarb X.X.X.99

Network Mask 255.255.255.128

Last Error  journal: InterSystems IRIS(IRIS)[2226]: AddVirtualAddress failed, cannot become primary: Host at osirispri:2188 ISCAgent answered :ERR:Failed to initialize config info.

I think something is wrong inside Primary, but a don't have any clue
