Ok thanks, but now I'm checking the rsdl (I should have done that earlier) and 
see :


disk.lun_storage.type


disk.lun_storage.logical_unit


logical_unit.id


logical_unit.address


logical_unit.port


logical_unit.target




Given the output for a existing SAN disk, I see :


SHP_MSA_2040_SAS_00c0ff26285a209135570100
HP
MSA 2040 SAS
33
1099511627776
0
dd98b206-08e4-48c0-9795-d10bc7581a95


There is no address, port or target, that are needed only for iscsi. I tried 
without and everything was fine. So I think they are not required.

When creating a LUN disk you need to specify the type (fcp or iscsi)
inside the "lun_storage" element, so you need to send an XML document
like this:

  
virtio

  fcp
  

  

To do that with the Python SDK you need the following code:

  params.Disk(
interface='virtio',
lun_storage=params.Storage(
  type_='fcp',
  logical_unit=[
params.LogicalUnit(
  id='0QEMU_QEMU_HARDDISK_drive-scsi0-0-0-2',
),
  ],
),
  )

[ovirt-users] creation of lun disks

[Fabrice Bacchella]

I'm trying to generated a lun disk, using the python SDK.

My code can be found at 
https://github.com/fbacchella/ovirtcmd/blob/master/ovlib/disks/__init__.py

If a try to see the content of a existing disk and test with :
print disk.get_type()
print disk.get_storage_type()

I'm getting :
None
lun

Now I try to create another LUN disk with
kwargs['storage_type'] = 'lun'
kwargs['type_'] = 'system'

I'm getting:

> POST /api/disks HTTP/1.1
> 
> system
> virtio-scsi
> 
> 
> 
> lun
> 
...
< 
< Incomplete parameters
< Storage [type] required for invoke0
< 

changing to 
kwargs['type_'] = None 
change nothing, I'm still getting the same error message.

 What did I do wrong ? There is nothing about that in the logs
