Hi guys,

I am seing multiple instances of the same LUN in Windows' Disk Management. I have read into this and found that this is due to PowerPath now being installed. After installing PowerPath, this issue was resolved, but only until the server was rebooted. Now no matter what i do, uninstall/reinstall PowerPath, the volumes are still displayed in doubles/triples. Here's the setup: EMC CLARiiON AX4-5SC running Navisphere Manager with FlareOE 02.23.050.5.711 (the latest release found on Powerlink). Brocade DS300-B Fiber Channel Switch. Microsoft Windows 2008 R2 server with Brocade FCHBA. The Server and storage have been zoned correctly. Software installed on the Host: EMC PowerPath 5.3 64bit (this is the latest version found on Powerlink and yet it has been released in 2008!?) and Navisphere Server Utility v29.0.6.1. Attached images showing the setup in detail. Could anyone please provide some insight as to what may have gone wrong in this setup? Also, is there really no newer version of PowerPath available?? http://imageshack.us/photo/my-images/802/hostoverview.jpg/ and http://imageshack.us/photo/my-images/577/navispheremanager.jpg/ Thanks for reading.
