Hello,
When deploying a fresh new RDSH VM with my unattended install script, the server appears in View Admin automatically and I can add it to a farm. So that part works. The script is good.
If I uninstall the agent (old version for example) and re-install the agent, with the same script, on the same RDSH VM, the installation works fine but the host stays in "not responding" mode. I have to remove it from the farm and then from the registered hosts, then re-install. Only then the host re-registers again without problems.
In other words, for some reason, the old entry of the exact same VM does not get overwritten. If I run the exact same script in Interactive mode, I get the message that the host is already registered and asks the question if I want to overwrite it. When I say yes, the host goes into the reachable state and all is fine.
So what i'm somehow missing is this "yes overwrite the existing entry" in unattended form. I need the unattended script to say "yes overwrite registration" so to speak. But I can't find anything in the documentation concerning unattended install parameters (the only parameters I can find are the Connection server name, the account and password).
