Mirrored rootdbs chunk is down problem

Hi all, got another problem for all you gurus. Our testing server is NT4-SP4 running IDS7.30 TC9 workgroup edition. The disk that has our mirror of the rootdbs space ran out of disk space - this brought the mirrored chunks down (rootdbs is made up of two chunks - one 30Mb the other 170Mb). The lack of space on disk has been fixed - it now has 200 - 300Mb free space. I've searched the archives for a solution regarding getting Informix back online. The main one proffered is to use: onspaces -s dbspacename -p chunkpath -o chunkoffset -O -y However, onspaces won't run without shared memory initialised and shared memory won't initialise while the rootdbs mirrored chunk is down! Does anyone know how I can fix this please? Seems like a catch-22 situation at the moment. Maybe there is some other utility I can use or configuration I can change? I tried turning of mirroring in ONCONFIG but that had no effect :-( Thanks for any help you can offer. Regards, Bryce Stenberg.
