Our xCAT postinstall script for creating RAMdisk images for our compute
nodes has:
# Now needed on and off respectively for RHEL 6.6
chroot ${1} chkconfig rdma on
chroot ${1} chkconfig ibacm off
The chroot is because the script runs outside of the area the RAMdisk
image is being constructed inside - we've used this for stock RHEL 6.6,
6.7 and 6.8 with Open-MPI 1.6, 1.8 and 1.10 without issues.
All the best,
Chris
