Adding the above line to the kernel on Mantic does not work - in fact setting values in /sys/class/scsi_host/host*/link_power_management_policy appears to get reverted during boot also. I have added this to rc.local but it changes back to med_power_with_dipm once the boot is completed. I have tried adding the kernel line, and also setting via systemd and cron tasks, it appears that something is reverting this setting.
