From 0c3ae2664766ec892992a686e48ead94784ef54c Mon Sep 17 00:00:00 2001 From: Cathy Avery Date: Mon, 17 Apr 2017 14:37:45 -0400 Subject: scsi: scsi_transport_fc: Add dummy initiator role to rport This patch allows scsi drivers that expose virturalized fibre channel devices but that do not expose rports to successfully rescan the scsi bus via echo "- - -" > /sys/class/scsi_host/hostX/scan. Drivers can create a pseudo rport and indicate FC_PORT_ROLE_FCP_DUMMY_INITIATOR as the rport's role in fc_rport_identifiers. This insures that a valid scsi_target_id is assigned to the newly created rport and it can meet the requirements of fc_user_scan_tgt calling scsi_scan_target.
