I think the issue is more the support rather than does it work. Like others I fully expect it to work just fine(as good as EMC stuff can be expected to work), but will they help you if CentOS is not a supported distribution? Some vendors will go out of their way to give a best effort support for unsupported configurations, others will not. Some understand that CentOS is practically identical to RHEL, others have a hard line drawn that says they won't support it. If whomever your getting support from won't support it if you have a problem then your probably best of getting a supported solution, or building a solution you could support yourself. I would expect EMC to publish docs on how to get device mapper MPIO to work with their systems, for those that have unsupported configurations for powerpath. Oftentimes the vendor's local SE can be a valuable support resource I lean on them a lot more than I lean on the formal support organizations as they often times have a better understanding of the particular customer environment, and the personal relationship inspires them to put an extra effort out to help to keep the customer happy. nate
