Hey I have a problem and I cannot find a solution.
Even though the Host utilization of 2 of my 7 hosts is around 30 % , DPM does not consilidate the VMs of these hosts and power one down.
I have already disabled HA ,power-off Cost benefit and DRS cost benefit evaluation. The DRS and DPM threshold is set to 5 and both are in automatic mode.
I do not have set any Affinity or Reservation rules, so there is no reason why both hosts are kept alive. I have been waiting for 12 Hours now.
What is really suprising is that when I manually migrate both vms onto one Hosts, I get the Power Off reccomendation a few minutes after it. I also get a Power off Migration if I reduce the host utilization on both hosts to 20 %. But in my Opinion 30 % should be enough to power down one host, as the utilization range is set to 45-81 percent. I have attached pictures regarding cpu and ram utilization
Does anyone have an answer what might cause the problem?
Thank you!
Hi,
can you post the logs files of the esxi host that shuts down?

Hey,
thank you very much for your help!
I am exporting the logs atm but it takes some time ( I will post as soon as it is finished). Is there any "event" I can look for myself in the logs?
Something I noticed: As long as the overall cluster utilization has been above 45 Percent (even though two hosts had a utilization below 30%), I didnt get the power off reccommendation. As soon as the utilization dropped below 45 Percent DPM initiated powering down one host. (see Attachment).
Could this be the problem? In particular: Does DPM only consider the overall cluster utilization for the power off reccomendation and as long as this is over 45 %, it wont generate a power off reccomendation? I dont think that its like that but it seems like it is.
