[ovirt-users] How do I activate a hot-plugged disk (in v3 Python SDK) ?

After successfully attaching a disk and verifying its status is in 'ok', I've tried: api.vms.get(VM0_NAME).disks.get(DISK1_NAME).set_active(True) But it doesn't really activate it. What's the correct way to activate it? (It works well via the UI). TIA, Y.
