Lost dbspace - how to remove the affected databases?

I have a Universal Server 9.12.UC2 "running". I have had problems with archiving using my Tandberg MLR1 tape drive (by the way, does anyone know how to configure such a drive for Informix?). One of the result of this is that one of my dbspaces was corrupted during a failed restore, and I can't get anything from my archive tapes. How can I remove all traces of the databases that were located on the "lost" dbspace? I have tried the FAQ, with no success. The manual only states that you must drop all databases and tables from a dbspace before dropping it. The command drop database <databasename> answers: 311: Cannot open system catalog (systables). 102: ISAM error: illegal argument to ISAM function.
