HA doens´t work if poweroff from DCUI???

Hello,

I was doing some tests in my customer environment. We have a cluster, 6 ESXI 6.1 U3.

When I connect to the DCUI and I poweroff the ESXi all the virtual machines running in this server poweroff and move to another ESXi host, but they don´t power on. My customer complains because he says that HA is not acceptable. I think it´s the normal way but I didn´t find any evidence.

If you can help me.

Thanks in advance.
