All usage related to the OBS node must be removed prior to deleting the node. When attempting to delete a node, guidance will be given if references to that node are still present. When deleting a Project OBS node, there can’t be any projects in that node (or project template). When deleting a Resource OBS node, there can’t be any resources, assignments, or current or past requests for that node. In both cases, both active and inactive reference instances must be removed.
If all of the above have been addressed and it is still not possible to remove the node, please contact PDWare Support for assistance.
