Mirroring the root dbspace during initialization in the chapter on using mirroring in the IBM Informix: Administrator's Guide

In Extended Parallel Server, MIRROROFFSET specifies the offset into the disk partition to reach the chunk that serves as the mirror for the initial chunk of each root dbspace.

You can specify MIRROROFFSET as a global configuration parameter to apply to all coservers. Optionally, you can also specify MIRROROFFSET in the coserver-specific section of the ONCONFIG file to override the global value if you want a different offset for a specific coserver.
