name : reboot-cache-cluster.rst **To reboot a cache cluster** The following ``reboot-cache-cluster`` example reboots some, or all, of the cache nodes within a provisioned cluster. This operation applies any modified cache parameter groups to the cluster. The reboot operation takes place as soon as possible, and results in a momentary outage to the cluster. During the reboot, the cluster status is set to ``REBOOTING``. :: aws elasticache reboot-cache-cluster \ --cache-cluster-id "my-cluster-001" \ --cache-node-ids-to-reboot "0001" Output:: { "CacheCluster": { "CacheClusterId": "my-cluster-001", "ClientDownloadLandingPage": "https://console.aws.amazon.com/elasticache/home#client-download:", "CacheNodeType": "cache.r5.xlarge", "Engine": "redis", "EngineVersion": "5.0.5", "CacheClusterStatus": "rebooting cache cluster nodes", "NumCacheNodes": 1, "PreferredAvailabilityZone": "us-west-2a", "CacheClusterCreateTime": "2019-11-26T03:35:04.546Z", "PreferredMaintenanceWindow": "mon:04:05-mon:05:05", "PendingModifiedValues": {}, "NotificationConfiguration": { "TopicArn": "arn:aws:sns:us-west-2:xxxxxxxxxx152:My_Topic", "TopicStatus": "active" }, "CacheSecurityGroups": [], "CacheParameterGroup": { "CacheParameterGroupName": "mygroup", "ParameterApplyStatus": "in-sync", "CacheNodeIdsToReboot": [] }, "CacheSubnetGroupName": "kxkxk", "AutoMinorVersionUpgrade": true, "SecurityGroups": [ { "SecurityGroupId": "sg-xxxxxxxxxxxxx836", "Status": "active" }, { "SecurityGroupId": "sg-xxxxxxxx7b", "Status": "active" } ], "ReplicationGroupId": "my-cluster", "SnapshotRetentionLimit": 0, "SnapshotWindow": "07:30-08:30", "TransitEncryptionEnabled": false, "AtRestEncryptionEnabled": false } } For more information, see `Rebooting a Cluster <https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Clusters.Rebooting.html`__ in the *Elasticache User Guide*.
