Setting BIOS Power Management Settings using syscfg

Hi

I have a number (~40) of old Dell-M610 servers, and want to change the BIOS settings for Power Management.  I can do this by rebooting the servers and going into the BIOS directly, but would prefer to set this using the Dell OpenManage Deployment Toolkit tools such as syscfg - the change would then be picked up after the next scheduled reboot.

My server details are as follows

  • Model: Dell-M610
  • OS-Arch: Centos Linux EL7-64
  • BIOS: 6.1.0

I've installed syscfg Version 6.1.0 and tried the folowing to check the current setting

# /opt/dell/toolkit/bin/syscfg power
power
cpupowermode=systemdbpm
fanpowermode=min
memorypowermode=max
profile=apc
cap=372W
minpowercap=336W
maxpowercap=372W
Showing I'm currently using the apc (Active Power Controller) profile, but want to change this to osctl (OS Control). I tried this 
# /opt/dell/toolkit/bin/syscfg power --profile=osctl --setuppwdoverride
power
profile=osctl
However checking the current setting showed no change, still using apc. Rebooting the system made no difference. This is probably something really simple, but any help here would be appreciated.

    Hello

    The command syntax looks correct. If you have a BIOS password set then it needs to be supplied in the command. If the BIOS password is enabled and you do not provide that information in the command the change will not be made.

    Make sure the system BIOS, iDRAC, and LCC are up to date. Also, I would test with changing something else using syscfg to try to find out if it is an issue with syscfg in general or that specific command. The OpenManage manuals can be found here:

    Thanks
