Allow brick to support other iSCSI transports besides TCP

Registered by Anish Bhatt on 2015-02-03

Currently open-iscsi in brick does not allow the use of offload iscsi transports (cxgb4i, qla4xx, bnx2i etc) or other software iscsi transports (like iser). This blueprint aims to add support for this

On the initiator side the only difference between TCP and other transports is in the interface flag (--interface=[iface])
e.g. "iscsiadm -m discoverydb -t st -p ip:port -I cxgb4i --discover"

Similar changes that went into nova can be seen here :

Besides supporting the iface parameter, _get_device_path() needs to be modified to support device paths that start with pci-XXXX-ip instead of ip

This actually sounds like a bug IMO, because it's missing functionality that existed prior to os-brick?
