In your case, you need to use elasticache_replication_group and pass number_cache_clusters = 3. num_cache_clusters is the total number of cache instances, so 3 = 1 master + 2 replicas All reactions aws elasticache describe-replication-groups \\ --region us-east-1 \\ --query 'ReplicationGroups[*].ReplicationGroupId' 2. Basically, the best you can do - when creating/adding read replica - is provide a cache cluster Id, a replication group Id and an availability zone and nothing else. A Redis ( cluster mode disabled) replication group is a collection of cache clusters, where one of the clusters is a primary read - write cluster and the others are read - only replicas. The reason this is occurring is because the availability_zones argument is not compatible with Redis Cluster Mode Enabled replication groups where there is more than 1 shard.. I'll use the Console . 0gc dsg . NOTE: ElastiCache Security Groups are for use only when working with an ElastiCache cluster outside of a VPC.
