Gavin2812,   As you can see below the option is available in OMSA, but as you suspected it would require a reboot to make the change.       [IMAGE]   Let me know if this helps.    
Hi all, I'm assuming the answer to this is 'NO', but I have this scenario. I have a number of R410's that will sit in a DC for DR purposes and I'm just over a certain power rating scale regarding pricing. If I set the servers in BIOS to 'minimum power' (as they'll be sat most of the time (hopefully!) not doing anything, but receiving data updates), if I needed to use them in anger, can this setting be changed via OMSA? Or will I have to shut down, change the power setting back to 'maximum performance' and reboot? The power difference between 'minimum power' and 'maximum performance' is enough to drop me into a lower power bracket but at the expense of having to reboot them to make the change again... Thanks in advance.
