I think this is a bug, and I didn't find any way to workaround it other
than creating the LUN using the GUI instead of the RESTAPI. I opened the
following BZ to track it:

 We have been able to get it to work but with one small annoyance. I
 can't figure out how to populate size,serial,vendor_id and product_id
 via the api. Would anyone be able to point me in the right direction ?

sys.exit(1)

iscsidet = params.IscsiDetails()

iscsidet.username=chap_user
iscsidet.password=chap_pass
iscsidet.target=target

host.iscsidiscover(params.Action(iscsi=iscsidet))
result = host.iscsilogin(params.Action(iscsi=iscsidet))

if result.status.state == 'complete':

storecon = params.StorageConnection()
storecon.address=portal
storecon.type_='iscsi'
storecon.port=3260
storecon.target=target
storecon.username=chap_user
storecon.password=chap_pass

ovirt_api.storageconnections.add(storecon)

return result
# error checking code needs to be added to this function

 def add_disk(vm_name,wwid,target,size,portal):

logunit = params.LogicalUnit()
logunit.id =wwid
logunit.vendor_id='EQLOGIC'
logunit.product_id='100E-00'
logunit.port=3260
logunit.lun_mapping=0
logunit.address=portal
logunit.target=target
logunit.size=size * 1073741824

stor = params.Storage(logical_unit=[logunit])
stor.type_='iscsi'


disk = params.Disk()
disk.alias = 'vm-' + vm_name
disk.name  = disk.alias
disk.interface = 'virtio'
disk.bootable = True
disk.type_ = 'iscsi'
disk.format='raw'
disk.set_size(size * 1073741824)
#disk.size=size * 1073741824
#disk.active=True

disk.lun_storage=stor

try:
result = ovirt_api.disks.add(disk)
except:
logging.error('Could not add disk')
sys.exit(1)

attachdisk=ovirt_api.disks.get(disk.alias)
attachdisk.active = True

try:

except:

sys.exit(1)

return result



 If we could just get the size to show correctly that would be enough,
 the others don't really matter to me.

Ah, I understand. This is probably related to the fact that you aren't
creating a storage domain, only the storage connection. This should work
correctly, but I guess that either the GUI or the backend aren't
completely prepared for this. I'm checking.

Re: [ovirt-users] Ovirt Python SDK adding a directlun

2014-05-08 Thread Gary Lloyd 
When I add direct Luns this way the size shows as <1 on the GUI and 0 when 
called from the rest api. All the other items mentioned are not present.

Thanks

For a direct LUN disk all these values are ready only. Why do you need
to change them?

[ovirt-users] Ovirt Python SDK adding a directlun

2014-05-08 Thread Gary Lloyd 
We are working on a script so that we can create an ISCSI LUN on our SAN
and then directly assign it to a vm.

We have been able to get it to work but with one small annoyance. I can't
figure out how to populate size,serial,vendor_id and product_id via the
api. Would anyone be able to point me in the right direction ? code (see
def add_disk):

def get_clusterid(cluster_name):
cluster = ovirt_api.clusters.get(cluster_name)
try:
return cluster.id
except:
logging.error('the cluster: %s does not appear to exist' %
cluster_name )
sys.exit(1)

def nominate_host(cluster_id):
for host in ovirt_api.hosts.list():
if host.cluster.id == cluster_id and host.status.state == 'up':
host.iscsidiscover
return host
logging.error('could not find a suitable host to nominate in cluster:')
sys.exit(1)


def iscsi_discover_and_login(cluster,target,portal,chap_user,chap_pass):
clusterid=get_clusterid(cluster)
host=nominate_host(clusterid)

iscsidet = params.IscsiDetails()
iscsidet.address=portal
iscsidet.username=chap_user
iscsidet.password=chap_pass
iscsidet.target=target

host.iscsidiscover(params.Action(iscsi=iscsidet))
result = host.iscsilogin(params.Action(iscsi=iscsidet))

if result.status.state == 'complete':

storecon = params.StorageConnection()
storecon.address=portal
storecon.type_='iscsi'
storecon.port=3260
storecon.target=target
storecon.username=chap_user
storecon.password=chap_pass

ovirt_api.storageconnections.add(storecon)

return result
# error checking code needs to be added to this function

def add_disk(vm_name,wwid,target,size,portal):

logunit = params.LogicalUnit()
logunit.id=wwid
logunit.vendor_id='EQLOGIC'
logunit.product_id='100E-00'
logunit.port=3260
logunit.lun_mapping=0
logunit.address=portal
logunit.target=target
logunit.size=size * 1073741824

stor = params.Storage(logical_unit=[logunit])
stor.type_='iscsi'


disk = params.Disk()
disk.alias = 'vm-' + vm_name
disk.name = disk.alias
disk.interface = 'virtio'
disk.bootable = True
disk.type_ = 'iscsi'
disk.format='raw'
disk.set_size(size * 1073741824)
#disk.size=size * 1073741824
#disk.active=True

disk.lun_storage=stor

try:
result = ovirt_api.disks.add(disk)
except:
logging.error('Could not add disk')
sys.exit(1)

attachdisk=ovirt_api.disks.get(disk.alias)
attachdisk.active = True

try:

sys.exit(1)

return result



If we could just get the size to show correctly that would be enough, the
others don't really matter to me.
