Informix versus AIX Mirroring

I want to create a mirrored database using Informix ONLINE 5.0 on an IBM RS/6000 running AIX 3.2.5. There are two ways to create this environment : 1. create a PRIMARY and MIRROR chunk and let Informix perform the mirroring operations 2. create a mirrored logical volume and let AIX do the mirroring I have used the first method in the past. However, I wonder if the second approach would give better results. What are the pros and cons of each method ? Is one method more reliable than the other ? Does one method result in better disk thoughput ? Which approach would be faster/easier when recovering from a disk failure ? Thanks in advance Steve -- Stephen M. Egan, Manager Soft. Eng.
