PowerPath can manage EMC and supported non-EMC storage.  In some cases, customers want to use PowerPath to manage EMC storage and another MPIO solution to manage non-EMC storage on the same host.  That is supported on most operating systems.  I would recommend reviewing the PowerPath Administration and Installation Guide for your OS to confirm.  Thanks, Brion
I have a question about hitachi storage use a power-path. Can Hitachi Storage use a EMC Power-path with EMC Clariion storage under same host? If this is avaiable, can I see the path information by powermt display's command?
