Before you allow them to go forward with your promotion process, ask yourself:

Do I have any grand slam papers, widely known and recognized?
What is my contribution? Is it widely recognized?
How do I compare with the top people in my cohort?
Do I have an extramurally-funded research program?

In book publishing fields, there are similar questions.

Do NOT compare yourself with people who have been tenured, telling yourself you are as good as they are. Some promotions are under retention pressures.. Others have been promoted, even as early as a few years ago, under a different standard than now prevails. And some people get promoted for reasons having little to do with their research.

Do compare yourself to the strongest promotions.

You are being compared not to people in your department, but to people throughout your university, and of course in so-called peer institutions. The strong professor files answer all the above questions rather strongly. Dean's letters can help, but if they are not supported by the dossier, they in fact prove to be killers.

But you really don't want to be denied, you really don't.

Only you can decide. These demurrers are meant as boilerplate. There are some departments, who if they put up a beagle for full professor, would have the provost wonder but say yes. Is your department one of those?
