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'] =3D 'lun'
kwargs['type_'] =3D 'system'
I'm getting:
POST /api/disks HTTP/1.1
<disk>
<type>system</type>
<interface>virtio-scsi</interface>
<lun_storage>
<logical_unit id=3D"3600c0ff00026285aed8f355701000000"/>

...
< <fault>
< <reason>Incomplete parameters</reason>
< <detail>Storage [type] required for invoke0</detail>

changing to=20

change nothing, I'm still getting the same error message.

What did I do wrong ? There is nothing about that in the logs
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:
<disk>
<interface>virtio</interface>
<lun_storage>
<type>fcp</type>
<logical_unit id="3600c0ff00026285aed8f355701000000"/>
</lun_storage>
</disk>
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',
),
],
),
)

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:
=20
<disk>
<interface>virtio</interface>
<lun_storage>
<type>fcp</type>
<logical_unit id=3D"3600c0ff00026285aed8f355701000000"/>
</lun_storage>
</disk>
=20
To do that with the Python SDK you need the following code:
=20
params.Disk(
interface=3D'virtio',
lun_storage=3Dparams.Storage(
type_=3D'fcp',
logical_unit=3D[
params.LogicalUnit(
id=3D'0QEMU_QEMU_HARDDISK_drive-scsi0-0-0-2',
),
],
),
)
=20
Ok thanks, but now I'm checking the rsdl (I should have done that =
earlier) and see :
<parameter required=3D"true" type=3D"xs:string">
<name>disk.lun_storage.type</name>
</parameter>
<parameter required=3D"true" type=3D"collection">
<name>disk.lun_storage.logical_unit</name>
<parameters_set>
<parameter required=3D"true" type=3D"xs:string">
<name>logical_unit.id</name>
</parameter>
<parameter required=3D"true" type=3D"xs:string">
<name>logical_unit.address</name>
</parameter>
<parameter required=3D"true" type=3D"xs:int">
<name>logical_unit.port</name>
</parameter>
<parameter required=3D"true" type=3D"xs:string">
<name>logical_unit.target</name>
</parameter>
</parameters_set>
</parameter>
Given the output for a existing SAN disk, I see :
<lun_storage id=3D"3600c0ff00026285a2091355701000000">
<logical_unit id=3D"3600c0ff00026285a2091355701000000">
=
<serial>SHP_MSA_2040_SAS_00c0ff26285a00002091355701000000</serial>
<vendor_id>HP</vendor_id>
<product_id>MSA 2040 SAS</product_id>
<lun_mapping>33</lun_mapping>
<size>1099511627776</size>

<disk_id>dd98b206-08e4-48c0-9795-d10bc7581a95</disk_id>
</logical_unit>
</lun_storage>
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.
