When RHEL 7.2 system boot up, the DSM service will not start. This happens because systemctl cannot read symlinks to SysV init service scripts in /etc/init.d. The scenario occurs after upgrading to RHEL 7.2 systemd-219-19-el7.
However, Red Hat stops the support for SysV init service scripts and suggests to migrate to systemctl. Before the next patch release, Trend Micro provides a workaround in this article.
Kindly contact Trend Micro Technical Support for the workaround.
