vROps delete esxi server objects

Hi all,

Recently, two ESXi servers has been removed out of our vCenter which is beeing monitored by vROps.

Since this environment is at kind of implementation phase, nobody thought about vROps at this moment. So they, of course, triggered "Host has lost conneciton to vCenter Server" Alerts. The Problem now is, that if I cancel these alerts, they reappear, because they are still not connected to vCenter (and never will be again).

My Question is, how can I delete them from vROps ? I tried already KB 2109276 (which basically leads to KB 2020638).

I configured it as followed:

deleteNotExisting=true

deletionSchedulePeriod=12

deletionPeriod=12

Did I miss something ?

We are running the following version:

vROps: 6.2.1.3774215 Build 3774215

vCenter: 6.0.0, 3634794

ESXi: 6.0.0, 3568940

Regards,

Stephan
