Hi Nicholas, In UNIX/Linux you have already MPIO build-in to the kernel and in RHEL/SLES you will only see one device. In Windows you need to go back to your HBA manufactory website and download MPIO driver for Windows and when you install them one of your changer and 4 drives will disappear.

Thanks for your help!! I am an old UNIX guy doing a Windows 2003 TSM 5.5.1 install. I have an x3650 system with a TS3310 library (4 x LTO4) and a DS4700 storage array. When I install the device driver for the library and boot the system, it comes back with 2 medium changers and 8 drives in the device manager rather than the 1 medium changer and 4 drives I really have. My SAN guy seems to think that this is OK but I have never seen it this way in UNIX land. Could it be that the zoning on the switch allows multiple paths to be seen by the system and therefore it is trying to identify the same drive twice. Should I leave it this way. If not what is the solution?
