Hi Piotr,
please check the following hidden settings to control the installation process:
tmsh list sys db liveinstall.* one-line
sys db liveinstall.checksig { value "disable" }
sys db liveinstall.longmode { value "enable" }
sys db liveinstall.moveconfig { value "enable" }
sys db liveinstall.movelicense { value "enable" }
sys db liveinstall.packageset { value "default" }
sys db liveinstall.saveconfig { value "enable" }
sys db liveinstall.savelicense { value "enable" }
Settings can be manipulated i.e. as follows:
tmsh modify sys db liveinstall.saveconfig value disable
Please do not use image2disk, even you probably see in the process list while running an installation.
For installing from .ucs the "no-license" switch will be your friend.
I used to have a copy of the /config/bigip.license in the /shared/directory/. Same with .ucs files (typically stored in volume´s local /var/local/ucs/ directory).
There is an easy way described to access another partition in this article.
Thanks, Stephan
