BIG-IP systems require all ISO images (base TMOS images and HotFix images) to be stored in a specific directory used for software installation:

/shared/images/

This directory:

Is theonly supported locationfrom which the BIG-IP software installation system validates and installs ISO files

Is accessible by both the GUI and TMSH installers

Has adequate storage space allocated specifically for images

Is part of the shared partition that persists across reboots

When transferring images via SCP, the administrator must copy them directly into/shared/images/so that:

The GUI (System → Software Management → Available Images) can detect the image

TMSH install software image commands can reference it

Other directories such as/local/images/or/var/images/are not valid storage paths for software images.
