Could you send me your multipath.conf/hwtable settings? Please find that file at the end of this e-mail. > For the fo/fb test, dev_loss_tmo is firing causing paths to be > added/deleted right? The script that I'm using to simulate path loss writes into /sys/class /srp_remote_ports/*/delete. That causes the ib_srp driver to call scsi_remove_host(). That script is available at https://github.com/bvanassche/srp-test. However, an InfiniBand HCA is needed to run this script.
