That's correct, we currently don't make an upcall for the SNS server port nor the switch fabric port. > # ls /sys/class/fc_remote_ports/ > rport-4:0-0 > # cat /sys/class/fc_remote_ports/*/roles > FCP Target > > Default dev_loss_tmo is 6 (1+5) while in Emulex case the default was 35. > > After disconnecting the cable between the HBA and the switch > qla2xxx 0000:03:01.0: LOOP DOWN detected (2). > rport-4:0-0: blocked FC remote port time out: removing target and saving binding > > # ls /sys/class/fc_remote_ports/ > rport-4:0-0 > # cat /sys/class/fc_remote_ports/*/roles > unknown > > Relevant scsi devices are removed from /proc/scsi/scsi. > > After reconnecting the cable > qla2xxx 0000:03:01.0: LIP reset occured (f7f7). > qla2xxx 0000:03:01.0: LOOP UP detected (2 Gbps). > > # ls /sys/class/fc_remote_ports/ > rport-4:0-0 > # cat /sys/class/fc_remote_ports/*/roles > FCP Target > > However, scsi devices don't reappear in /proc/scsi/scsi. > When I issue rescan, the command is stuck > echo - - - > /sys/class/scsi_host/host4/scan > > Please advise. Could you add the enable-debug patch I sent you earlier and retry the test? Again forward the relevent snippets from var/log/messages.
