Title:
  Hyper-V won't disconnect iSCSI targets created by tgt

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  When detaching volumes, the Hyper-V driver decides whether the iSCSI
  target should be disconnected or not by comparing the number of
  volumes being disconnected and the total number of available LUNs of
  the according iSCSI target.

  This causes problems as TGT exports one extra reserved LUN. For this
  reason, the according iSCSI targets won't be disconnected when a
  volume exported by TGT is detached.

  The fix consists in checking the disk types when counting the
  available LUNs of a target.
