Brian King d5b45dd5ba scsi: ibmvfc: Handle move login failure ... When service is being performed on an SVC with NPIV enabled, the WWPN of the canister / node being serviced fails over to the another canister / node. This looks to the ibmvfc driver as a WWPN moving from one SCSI ID to another. The driver will first attempt to do an implicit logout of the old SCSI ID. If this works, we simply delete the rport at the old location and add an rport at the new location and the FC transport class handles everything. However, if there is I/O outstanding, this implicit logout will fail, in which case we will send a "move login" request to the VIOS. This will cancel any outstanding I/O to that port, logout the port, and PLOGI the new port. Recently we've encountered a scenario where the move login fails. This was resulting in an attempted plogi to the new scsi id, without the old scsi id getting logged out, which is a VIOS protocol violation. To solve this, we want to keep tracking the old scsi id as the current scsi id. That way, once terminate_rport_io cancels the outstanding i/o, it will send us back through to do an implicit logout of the old scsi id, rather than the new scsi id, and then we can plogi the new scsi id.
