Hi,

What do you mean by controller status?

After some digging I found that, when using
cinder.volume.drivers.lvm.LVMVolumeDriver, it seems that cinder searches
for the VG, and the VG must exist.
Seeing some examples like this [1], it's like the configuration is made to
expose a local disk as an iscsi LUN.

The VG was created on a local disk, then it was exposed as LUN. So just to
be sure, is cinder.volume.drivers.lvm.LVMVolumeDriver with target_protocol
= iscsi, intended to expose a local VG on compute nodes as iscsi LUNs?

My other question is : Can I configure cinder with  Tagetcli as external
iscsi storage?
