We seem to see four versions of the disc: one for each route (2 HBAs x 2 FC switches to SAN). PowerPath is new here, so trying to get a handle on this. -sc From: Jim Holmgren [mailto:jholmg...@xlhealth.com] Sent: Thursday, July 29, 2010 8:59 AM To: NT System Admin Issues Subject: RE: EMC Powerpath and Windows 2008 R2 I'm running PowerPath v5.3 (build 11) on a 2008R2 server connected to my CX4-240. I haven't seen this behavior. Dell r710 with QLogic HBAs. To the best of my understanding, you are correct - PowerPath basically makes sure that even though there are multiple physical paths to the target LUN, only one is 'seen' by Windows.

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. Bill Mayo ________________________________ From: Ziots, Edward [mailto:ezi...@lifespan.org] Sent: Thursday, July 29, 2010 8:32 AM To: NT System Admin Issues Subject: EMC Powerpath and Windows 2008 R2 Folks, Is anyone out there using EMC powerpath with Windows 2008 R2, to present LUN's from an EMC SAN to servers/Clusters etc etc? 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.
