HI,

I have two node VMware 6.5 HA Clusters. and I have lots of resources to failover. I have selected the admission control by percentage usage %50 percent.

However unless I disabled admission control, HA wont migrate the powered on VMs saying there is no enough resources to failover.

Please look a the screen shot to see that there are lots of resources

any ideas ?

I am sorry,

I thought I have attached an image file. here is the screen shot for Cluster resources and the Admission control setting.

as for VMs, I have only one VM with 10 GB HDD and 4 GB ram.

HA only works with admission control disabled for the time being

Pls see the attached files

CPU and Memory for all hosts and VMs.
in 6.5 , it turns out that HA requires 3 hosts. we have called VMware support, they were not also aware.

So with 2 host doesn't work. needs three at least
