[bioontology-support] help loading rxnorm to ncbo virtual appliance

Quick question for the bioportal admin tool.
There is a deprecate/delete ontologies link under bioportal admin. Can we remove the unsuccessfully loaded ontology with this link?

I'm looping Lian in to this conversation to see if he has any insight (Pradip has moved on to another project, so Lian is the contact at Mayo now). One of the things I can think to check is disk space. Is it possible that it's filling up the space you have available on the Appliance?
Lian -- any other ideas?

Initially, a zip file with a dummy RRF file is loaded through the new ontology screen of bioportal (../ontologies/new). The folder where the appliance is placing the ontology files is then determined, and the local rxnorm RRF files are copied to this directory.

This seemed to occur when a previous attempt at loading RxNorm had failed and I tried to load it again under a different name without reloading a fresh copy of the appliance into VirtualBox.
