To find related files: find / ! -type d -links +1 -print | xargs ls -li | sort -n If you don't include the '! -type d' condition, use 'ls -lid' to list directories as directories, rather than as their contents. However, you are more likely to use symlinks to the devices than hard links; hard links are tied to a single file system but symlinks can make a connection between two different file systems. Generally, you'll find your links fairly close to the Informix software, but there is no requirement that this is what happens. A single OnLine instance could be set up with one chunk in /file/system/A, another in /B.file.system, and both of these chunks are actually symlinks to two different raw devices in two different logical volumes handled by the logical volume manager, and other more bizarre setups.
