What were you trying to do that didn't work?
On a system with both FC LUNs and NVMe-FC namespaces, I enabled device-mapper-multipath and added the following line to the defaults section of /etc/multipath.conf:
marginal_pathgroups fpin
multipathd was then restarted and I began to send link integrity events from the Brocade switch (/fabos/cliexec/ftc test --fpin 020700 -li -link_failure). At that point, I was able to see port_states become Marginal which is what I expected:
[root@storageqe-14 ~]# for i in `find /sys -name port_state | fgrep rport`; do echo $i; cat $i; done /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-2/fc_remote_ports/rport-10:0-2/port_state Online /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-0/fc_remote_ports/rport-10:0-0/port_state Online /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-7/fc_remote_ports/rport-10:0-7/port_state Online /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-5/fc_remote_ports/rport-10:0-5/port_state Marginal /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-3/fc_remote_ports/rport-10:0-3/port_state Online /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-1/fc_remote_ports/rport-10:0-1/port_state Online /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-8/fc_remote_ports/rport-10:0-8/port_state Online /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-6/fc_remote_ports/rport-10:0-6/port_state Online /sys/devices/pci0000:40/0000:40:01.1/0000:41:00.0/host10/rport-10:0-4/fc_remote_ports/rport-10:0-4/port_state Marginal
I then disabled/enabled the switch port to clear the condition. Furthermore, I removed all the FC LUNs by running the following command:
- echo 1 > /sys/block/sdc/device/delete
Now I only have NVMe namespaces monitored by device-mapper-multipath:
[root@storageqe-14 ~]# multipath -ll mpatha (uuid.cf79fefe-a141-4cd8-921e-f2c57511718e) dm-8 NVME,NetApp ONTAP Controller size=50G features='1 queue_if_no_path' hwhandler='0' wp=rw |-+- policy='service-time 0' prio=50 status=active | `- 8:41408:5:5 nvme8n5 259:19 active ready running |-+- policy='service-time 0' prio=10 status=enabled | `- 7:41409:5:5 nvme7n5 259:12 active ready running |-+- policy='service-time 0' prio=50 status=enabled | `- 5:41472:5:5 nvme5n5 259:4 active ready running `-+- policy='service-time 0' prio=10 status=enabled `- 6:41473:5:5 nvme6n5 259:5 active ready running
I again issue the same FPIN link integrity events from the switch. Although I can see the link_failure counters increment, the port_state remains Online:
- cat /sys/class/fc_host/host10/statistics/fpin_li_link_failure_count
0xa
