Hi,
We are using Informix Dynamic Server Version 7.30.UC3 on Siemens Unix
RM600 v5.43 C2003. Our backup plan is as follows:
Level 0: 8mm / 7GB tape
Level 1: 4mm / 2GB tape
We are now doing a restore. The Level 0 restore went fine. Then it
asked if we wanted to restore Level 1 and Logical Logs, to which I
typed "n" to quit. I changed the TAPEDEV and TAPESIZE parameters using
onmonitor to do Level 1 restore. Then I got this msg after running
ontape -r:

Does Informix support restore from different Level 0 and Level 1 media?
Before we have tried using 4mm/4GB tapes for Level 0 and 4mm/2GB tapes
for Level 1 successfully. Why doesn't it work now? Please help me.
Thanks.
