HA Admission Control and DPM with clusters with 3 and 2 hosts
Hi everyone,
I have two clusters, first with 3 hosts and second with 2 hosts. And I have couple questions about enabling DPM:
In 3 hosts cluster HA/DRS I enabled Admission Control to Percentage of cluster resources reserved as failover spare cpacity to 33%. Because I don't have any VM on this cluster, when I enabled DPM it put 2 hosts to standby mode. And now when I want powered on any VM on this cluster I get error "The operation is not allowed in the current state". It's possible only when I disable Admission Control - but then I lose HA protection. So in 3 nodes cluster I should always have 2 powered on hosts when VMware HA strict admission control is enabled? It's possible only when in DPM options I disabled power management on 2 hosts. Am i right? And DPM will only put on/off my third host (for example brings host out of standby mode to maintain failover needs)?
In 2 hosts cluster when I enable Admission Control (50%) I should disable DPM, because I need always have 2 powered on hosts?
