Cluster problems can prevent DRS from performing optimally or from reporting faults. What to read next Load Imbalance on ClusterA cluster has a load imbalance of resources. Cluster is YellowThe cluster is yellow due to a shortage of resources. Cluster is Red Because of Inconsistent Resource PoolA DRS cluster becomes red when it is invalid. It may become red because the resource pool tree is not internally consistent. Cluster Is Red Because Failover Capacity Is ViolatedA DRS cluster becomes red when it is invalid. It may become red because failover capacity is violated. No Hosts are Powered Off When Total Cluster Load is LowHosts are not powered off when the total cluster load is low. Hosts Are Powered-off When Total Cluster Load Is HighHosts are powered off when total cluster load is high.
