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:

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.

zesty verification is done.
