Hello Ronnie, Have you considered to allow multiple /dev/sg* arguments to be specified and to let the tests that require multiple I_T nexuses use one /dev/sg* argument per nexus ? Do you think such a feature would be helpful for testing FC and RDMA over SCSI initiator drivers in a setup with multiple storage paths between initiator and target systems ? Thanks, Bart.
