Weird duplicate device in Win2003 install

Hello All!

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 LT) 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 K 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?
