While updating from 9.x to 9.7 via GUI im getting this error message:
“Failed to add the software image to the cluster.
The request body must have content type multipart/form-data with a field named file”
The solution is very easy: starting with ONTAP 9.7, the image size is above 2 GB and the cluster cannot upload it correctly. To fix this issue, you need to increase the maximum upload size and wait for the job to finish:
set diagnostic; system services web file-uploads config modify -node * -size 4GB
After this, you can upload and install your ONTAP 9.7 via GUI 🙂
