The problem has been resolved, apparently it was an expired license.
It did still take some testing though, to get it to be responsive so i could run a manual IPL.
I had to go power on with D M configured, create a new connection in Operations Console, power down, power up with A M configured, then connect to the newly created connection, and login with QSRV.
IBM 9406-550 System i
After some network trouble had passed in our test environment, there seemed to be no more problems. However after a while, the system had lost its IP's. I could no longer connect via 5250 emulator or System Navigator for i. I checked if it was the network again, but all the desired ports are open between me and the server. I tried connecting my laptop to the same switch as the System i, but no dice.
So i connected via Operations Console and a manual IPL, but on the IPL or Install The System page, any of my choices would go unnoticed to the system. My selected number would disappear, and nothing would happen. Only when i disconnect and connect to the console, it would prompt the DST Sign On page.
From here i could enter in username and password, but again after pressing enter, nothing happened. No wrong password messages or any error code of any kind. I know the password for QSECOFR, but it wont even try to log in.
I could still go back (F3), but it would then be stuck in the first menu again. Basically the system seems unreachable, and this has happened a few times before, where i had to resort to a full clean install of the OS.
I would love to know if anyone has some input, as tQSECOFR was disabled.o how i can gain access to my system again. It is quite a pain to continuously reinstall the OS, as im sure most of you know.
Thanks in advance.
