tgt uses scsi host_no as it_nexus. This works for ibmvstgt because it creates one scsi host for one it_nexus. However, this doesn't work for some target drivers. I added it_nexus support and modified ibmvstgt to use it. It needs to be polished before it goes to scsi-ml. But I applied this to my trees since this has been long overdue and some people want to try it, I guess. The user/kernel interface was changed so get and compile the latest user-space and kernel-space code. |
