Yeah, it seems to work. The next step is to find out specifically which /dev nodes need to be passed in, so we can add those to the Dockerfile LABELs parsed by the atomic tool when creating an SPC. That's if you wanted to go that route.
For example, I did this for another image:
LABEL RUN="docker run -it --privileged -v /sys/bus/pci/drivers:/sys/bus/pci/drivers -v /sys/kernel/mm/hugepages:/sys/kernel/mm/hugepages -v /sys/devices/system/node:/sys/devices/system/node -v /dev:/dev --name NAME -e NAME=NAME -e IMAGE=IMAGE IMAGE"
For MegaRAID, something like this:
# cat Dockerfile
FROM rhel7/rhel-tools
MAINTAINER redhat redhat com
COPY ./MegaCli-8.07.08-1.noarch.rpm /root/
COPY ./megaraid-profile.sh /etc/profile.d/
RUN yum localinstall -y /root/MegaCli-8.07.08-1.noarch.rpm
LABEL RUN="
# cat megaraid-profile.sh
export PATH=$PATH:/opt/MegaRAID/MegaCli
# docker build -t megaraid .
# docker run --privileged -it megaraid /opt/MegaRAID/MegaCli/MegaCli64 -EncInfo -aALL
