Thanks, Yuriy.
My question was: how can I retrieve the "host@backend#pool" from the
pythonclient API of volume listing? Once I have that, I should use this
method to extract the pool-name.
But how can I access this info? CLI is showing this as in the following
field:
stack@openstack4:~/devstack$ cinder show
e8be1df5-64fb-43fa-aacd-9bebba17fba5

Now in python client API, I am not able to get that field :(
>>> volumes = cinder.volumes.list()
>>> volumes
[<Volume: e8be1df5-64fb-43fa-aacd-9bebba17fba5>]
>>> type(volumes[0])
<class 'cinderclient.v2.volumes.Volume'>
>>> volumes[0].id
u'e8be1df5-64fb-43fa-aacd-9bebba17fba5'
>>> volumes[0].host
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/usr/local/lib/python2.7/dist-packages/cinderclient/openstack/common/apiclient/base.py",
line 464, in __getattr__
raise AttributeError(k)
AttributeError: host
>>> volumes[0].os-vol-host-attr
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File

raise AttributeError(k)
AttributeError: os
Essentially what is the way to get the attribute from the API?
Thanks,
Pradip
