Hello Guys, I am using cinder on centos7 stein with Dell unity iscsi driver. When I migrate vm from a kvm node to another, orphaned devices are left on source kvm node. I initialized debug on nova compute and i thing the issue si in the following lines (2020-10-20 09:52:33.078 132171 DEBUG os_brick.initiator.connectors.iscsi [-] Disconnecting from: []):
