you are right, i wrote wrong. They are optional

The verification is based on list with disks keys, to verify if all of
them where passed.
When working with optional parameters, is it ok to removing the from
the verification, like this:
for param in optional_param:
keys.remove(param)
If you are working with optional parameters, you should not use this
same logic to do that.
That logic is validating a set of required parameters given a type of disk.
