With an hotfix of 7.6 was possible to install an AIX RSCD agent silently with the following in the nsh-install-defaults:
STARTUP_AIX=1 (Use /etc/rc.tcpip)
STARTUP_AIX=2 (no startup file)
STARTUP_AIX=3 (Use /etc/rc.d/init.d/rscd)
In version 8 this does not work. So the agent start configuration goes straight in /etc/rc.tcpip.
But ... to stop an agent? kill -9 PID?
