I need to create a custom script for HP 1900 series switches for configuration backups as the builtin HP one does not support these models. But I could not find where are these scripts. They are not in "Administration -> Scripts" page on OneView.
The issue mentioned in the below article is created for a different issue but it outlines the procedures on how you can copy existing and create a custom script, to backup devices from inventory manager. I hope this is what you are looking for!
