So you are pretty certain that it's simply seeing the same disk via different paths? If that is the case, and PowerPath is installed, I would take it up with EMC support. Bill Mayo

We have a DMX 1000 SAN, on the backend and Qlogic HBA's on the server, along with the Powerpath V5.3 SP1, which claims via the documentation to support Windows 2008 R2. Z Edward E.

Are you using MirrorView? If so, it is possible that you are seeing the mirror copy of the disk as well as the original.

My SAN Guy, basically is telling me that the role service of Multipath I/O is added to the server when the EMC Powerpath is added but when the drives are presented we are seeing two disks in disk management, not one, which the Multipath software in EMC Powerpath is supposed to take care of. ( We are using Version 5.3 SP1, on X64 Windows 2008 R2) Nothing showing up on the EMC site accordingly, Any ideas accordingly? Z Edward E.
