CreateDiskReplicaGroup -

Usage notes

The replication pair-consistent group feature allows you to batch manage multiple disks in disaster recovery scenarios. You can restore the data of all disks in the same replication pair-consistent group to the same point in time to allow for disaster recovery of one or more instances.

Take note of the following items:

For information about the regions in which the replication pair-consistent group feature is available, see Overview.
Replication pair-consistent groups can be used to implement disaster recovery across zones within the same region and disaster recovery across regions.
A replication pair and a replication pair-consistent group replicate in the same direction if they have the same primary region (production region), primary zone (production zone), secondary region (disaster recovery region), and secondary zone (disaster recovery zone). A replication pair can be added to only a replication pair-consistent group that replicates in the same direction as the replication pair.
After replication pairs are added to a replication pair-consistent group, the recovery point objective (RPO) of the group takes effect on the pairs in place of their original RPOs.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter	Type	Required	Example	Description
Action	String	Yes	CreateDiskReplicaGroup	The operation that you want to perform. Set the value to CreateDiskReplicaGroup.
RegionId	String	Yes	cn-beijing	The ID of the region in which to create the replication pair-consistent group. The primary site is deployed in the region.
SourceZoneId	String	Yes	cn-beijing-f	The zone ID of the primary site.
DestinationRegionId	String	Yes	cn-shanghai	The ID of the region on which the secondary site is deployed.
DestinationZoneId	String	Yes	cn-shanghai-e	The ID of the zone on which the secondary site is deployed.
GroupName	String	No	myreplicagrouptest	The name of the replication pair-consistent group. The name must be 2 to 128 characters in length. The name must start with a letter and cannot start with `http://` or `https://`. The name can contain letters, digits, colons (:), underscores (_), and hyphens (-).
Description	String	No	This is description.	The description of the replication pair-consistent group. The description must be 2 to 256 characters in length and cannot start with `http://` or `https://`.

You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.
RPO	Long	No	900	The RPO of the replication pair-consistent group. Unit: seconds. Set the value to 900.
Bandwidth	Long	No	5	The bandwidth value. Unit: Kbit/s. Note This parameter is not publicly available.
ResourceGroupId	String	No	rg-acfmvs*******	The ID of the resource group to which to assign the replication pair-consistent group.
Tag.N.Key	String	No	tag-key	The key of tag N to add to the replication pair-consistent group.
Tag.N.Value	String	No	tag-value	The value of tag N to add to the replication pair-consistent group.
