The host must be powered on to help provide more capacity for the cluster or help hosts that are overloaded.


DRS recommends that the host is powered on to increase capacity when the total cluster load is low.


The recommendation might be made because:

  • The cluster is a DRS-HA cluster. Additional powered-on hosts are needed to provide more failover capability.
  • Some hosts are overloaded and virtual machines on currently powered-on hosts can be moved to hosts in standby mode to balance the load.
  • The capacity is necessary to meet the MinPoweredOn{Cpu|Memory}Capacity advanced options.


Power on the host.
