Description Dan Horák 2020-08-20 13:44:59 UTC 
Under some conditions the zfcpconf.sh script fails, I believe it's when multipath is used. See bellow for journal content when booted with rd.udev.debug

There are 2 instances started, one succeeds, the other fails. The result (discovered and enabled disks) isn't affected by this behaviour.

Comment 1 Dan Horák 2020-08-20 15:43:24 UTC 
I suspect it can't be fixed with the current device initialization infra.

for the records ... zfcpconf.sh is an addition to s390utils from Red Hat.
