Public bug reported:

If you try to attach a NetApp iSCSI volume to a Hyper-V compute host,
the request is not performed due to a type missmatch in the following
line:

https://github.com/openstack/nova/blob/b6a5ce00a0f767da2538b70d5e6d4c998a8e15e0/nova/virt/hyperv/basevolumeutils.py#L135

"if device.ScsiLun == target_lun:"

'device.ScsiLun' returned by WMI is an 'integer', while 'target_lun'
reported by the Cinder NetApp iSCSI driver is an 'unicode' string.

I'm not sure if this should be also reported to Cinder. Is there any
specification on the Cinder side that specifies the expected data type
for that field?
