dasdfmt -y -b 4096 -d cdl -f /dev/dasdb

there no '-f' option in new version of s390utils-base:
[root@cindervm ~]# rpm -qa | grep s390utils-base
s390utils-base-2.1.0-2.el7a.s390x

But zthin will work on its version of:
[root@myzcc ~]# rpm -qa | grep s390utils-base
s390utils-base-1.23.0-41.el7.s390x
