Removing a Data Collection Device (DCD) from a cluster that contains statistics data may cause the cluster to contain one or more unassigned data shards.


When the DCD elastic search cluster transitions to "red" status, the cluster may become unusable.


You desire to remove a DCD when statistics collection is enabled for one or more BIG-IPs.


The following workaround can be performed: 1. Log into BIG-IQ as an administrator 2. Click on the "System" tab 3. Open up the "BIG-IQ Data Collection" on the left navigation menu. 4. Click on "BIG-IQ Data Collection Devices" 5. Click Add, and enter the DCD's information. Once successfully added to the BIG-IQ cluster, you will need to enable statistics data replication: 1. From the BIG-IQ Data Collection Devices user interface, click "Settings". 2. Then, click Statistics Collection 3. Click Configure 4. Click Advanced Settings 5. Check the box next to "Enable Replicas" 6. Click Save & Close Next, wait for the elastic search cluster to show a status of Green, then the DCD can removal can be re-tried.
