IM installation fails with an error message: ERROR Error during switching: Spec file not found


Upgrading/Downgrading to another IM does not work until you install a new BIG-IP image on the same disk.


This can occur when deleting an IM file that is actively installing on one volume, and the BIG-IP system is booted from another volume.



Fix Information

During the init process, the system now installs FactoryDefaults if the active IM file is not found on disk.
