Need help with dbexport on tape

Hello out there, currently we're trying to export a database to tape. We type dbexport dbname -t /dev/rmt/0m -b 16 -s 4194304 but then we get the error message Block size must be less than or equal to tape size So we've played arround a little bit and have discovered that there is a magical limit of 2 GB for the tape size. We're using INFORMIX-Online DSA 7.13.UC3 on HP-UX 10.01. Are there work arrounds for this problem? Do we need a newer release of Online? Any hints are welcome. Thanks in advance...
