Starts a disaster recovery drill in a replication pair-consistent group to ensure the continued replication and restores data from the latest recovery point of secondary disks to new disks. This helps test the completeness and correctness of applications that are deployed on the disaster recovery site on a regular basis.
Operation description
After the disaster recovery drill is complete on secondary disks, a pay-as-you-go drill disk is created in the zone where the secondary disk of each replication pair resides. The latest-recovery-point data is restored to the drill disks to test the completeness and correctness of applications.

Request parameters
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| RegionId | string | Yes | The ID of the region where the secondary site in the replication pair-consistent group is located. You can call the DescribeDiskReplicaGroups operation to query the region where the secondary site in the replication pair-consistent group is located. Note
You must enable the disaster recovery drill feature in the region in which the secondary site resides.
| cn-hangzhou |
| GroupId | string | Yes | The ID of the replication pair-consistent group ID. You can call the DescribeDiskReplicaGroups operation the most recent list of async replication pair-consistent groups, including group IDs. | pg-xxxx |
| ClientToken | string | No | The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests.
