tbtape -r won't restore the online

Hi, I have an old informix 5.0 system installed that I use for a small database. I use a cooked unix file for the database. Works fine. I archive it to a unix file using 'tbtape -s' and the archive is done fine into /usr/tapedev(LTAPEDEV) file. My database disk went bad. I replaced it. Now I am trying to restore the data. Here is what I am doing: $tbinit -i //The informix comes up fine with new cooked dbspace $tbmode -ky //bring informix offline $tbtape -r And I get: Rootpath = /dev/online_root.ah.file,Offset = 0 K, Size = 50000 K. Mismatch in configuration file. But my informix installation area is untouched, so the config. file is as it was before. Here is relevant config. lines I am using: ROOTNAME rootdbs # Root dbspace name ROOTPATH /dev/online_root.ah.file ROOTOFFSET 0 # Offset of root dbspace into device (Kbytes) ROOTSIZE 50000 # Size of root dbspace (Kbytes) TAPEDEV /tmp/tapedev # Archive tape device pathname TAPEBLK 20 # Archive tape block size (Kbytes) TAPESIZE 60000 # Max amount of data to put on tape (Kbytes) LTAPEDEV /dev/null # Logical log tape device pathname LTAPEBLK 20 # Logical log tape block size (Kbytes) LTAPESIZE 60000 # Max amount of data to put on log tape Any pointers ? Pls also CC me in your reply. Thanks AH
