Hi,

In order to reproduce this issue you need a test lab with FC connection only (no ISCSI) between hosts and storage.

The easiest way to reproduce:

1. delete all LUNs if they already exist on host so the host will be disconnected from storage, you will se a warning in the log indicating that no volumes mapped:
https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/ibm/storwize_svc/storwize_svc_common.py#L1223

2. create a new LUN - for example, start a VM booted from volume on the host from 1.

3. Check on Storwize Web UI that the host is now in Degraded state, this is because it was connected via ISCSI port which is unavailable.
