To see which RAID functions are supported by iDRAC, see this document (starting on page 191):

There are 3 other vdisks listed in the "Storage->Virtual Disks" section of the iDRAC7 interface: vdisk0, vdisk2, and vdisk3. It's vdisk1 that I'm trying to get to appear. Scott Kingston's response gave me enough information to confirm that iDRAC 7 does not support creating a vdisk via that interface, so right now I'm looking at the remote access options via other tools. Thanks!
