Why is DISKPART showing 2 entries per LUN?

I am running a 2 node RAC on Windows 2008R2.  Last week I requested 3 new disks be added on the servers so that I could create a new DiskGroup in ASM.  I went thru the normal steps to create the partition and then create the DiskGroup.   But when creating the database I got an error saying that the second node couldn't see the disks.  I called our support guys as they had done the original presentation.  They worked on it and I finally got the database up, but only on one node. 

When doing a DISKPART on each RAC server, I see a duplicate entry for each disk.  For example, if I have 23 disks, then I will see 46 entries when I LIST DISK.  Looks like the second set of 23 is a copy of the first 23.  However, those are really not true disks at all.   Further, when the 3 new disks got added last week, the DISKPART showed the 3 new disks at the end of the DISKPART list as numbers 47, 48, 49, 50,51, and 52.  Of those, only 47, 49, and 51 were true disks with space
