Affinity rules with vcenter down

[gongi]

Hello,

I was wondering if the policies and affinity rules configured in a vCenter continue to work even if the vCenter is down (like vSphere HA).

Thanks

Hi,

"DRS" rules are rules managed by the vCenter.  Without vCenter no management of DRS rules

For the HA indeed, it is set up by the vCenter but as information is written on each ESXi, even in the event of loss of the vCenter, the device remains available.

Thanks for the quick reply.

So while HA is written on any ESXi host, DRS rules are only "known" by vCenter and, if it is down, DRS won't work. Am I correct?

Hi,

You are right.

anyway, without vCenter there is no vMotion so no possibility for your vms to migrate to another ESXIs

HI,

I come back to this discussion. Because I read an article about vCLS service from VMWare 7.0 U1.
This service allows you to disconnect DRS and HA services from vCenter.

Sorry for the inaccuracy of my previous answer, but we are still on version 6.7.
