Started zesty container with s390-tools 1.37.0-0ubuntu3. Reproduced the
problem using the simplified upstream test case:
$ chzdev -e -p zfcp-lun 0x0000:0x0000000000000000:0x0000000000000000
$ chzdev -e -p zfcp-lun 0x0000:0x0000000000000001:0x0000000000000000
$ chzdev -e -p zfcp-lun 0x0000:0x0000000000000000:0x0000000000000001
The generated rules were:
LABEL="start_zfcp_lun_0.0.0000"
SUBSYSTEM=="fc_remote_ports", ATTR{port_name}=="0x0000000000000000",
GOTO="cfg_fc_0.0.0000_0x0000000000000000"
SUBSYSTEM=="fc_remote_ports", ATTR{port_name}=="0x0000000000000001",

Observe how duplicate ..0 labels and goto end result in inability to
reach the unit_add}="0x0000000000000001" paragraph.
Upgraded to 1.37.0-0ubuntu3.1. Disabled all of these devices and re-
eneabled them.
$ chzdev -d -p zfcp-lun 0x0000:0x0000000000000000:0x0000000000000000
$ chzdev -d -p zfcp-lun 0x0000:0x0000000000000001:0x0000000000000000
$ chzdev -d -p zfcp-lun 0x0000:0x0000000000000000:0x0000000000000001
$ chzdev -e -p zfcp-lun 0x0000:0x0000000000000000:0x0000000000000000
$ chzdev -e -p zfcp-lun 0x0000:0x0000000000000001:0x0000000000000000
$ chzdev -e -p zfcp-lun 0x0000:0x0000000000000000:0x0000000000000001
The new rules combine the ...0 and ..1 devices under non-duplicate
label, thus all states are now reachable.
