Splitting a TrueCopy or Universal Replicator pair through the DR Operator temporarily stops data replication between primary and secondary volumes, allowing independent access to the secondary volume for backup, testing, or recovery purposes.

Verify the DR policy is created. See Creating and managing Disaster Recovery Policy for a TrueCopy pair or a Universal Replicator pair.

Apply the DR policy with desiredState set to split. Enter:

kubectl patch drpolicy <drpolicy-cr-name> --type=merge -p '{"spec":{"desiredState":"split"}}'

Verify if the DR policy is applied on both the primary and secondary sites. Enter:

kubectl get drpolicy

Sample output:

kubectl get drpolicy
NAME                  SOURCE_CLUSTER   TARGET_CLUSTER   REPLICATION_TYPE   DESIRED_STATE   STATUS      CTG_ID   AGE
sample-app-drpolicy   site-61          site-62          sync               split           Unhealthy   21       18m

Verify the replication status of the PVCs. Enter:

kubectl get replication -A

Sample output:

NAMESPACE   NAME                                               STATUS   DESIREDSTATE   OPERATION   AGE
