Creating an EVS Replication Pair (Deprecated)

Function

This API is used to create an EVS replication pair using a specified production disk and a disaster recovery (DR) disk. The production disk is in the primary AZ, and the DR disk is in the secondary AZ.

NOTE:

This API has been deprecated. To use this function, see Storage Disaster Recovery Service API Reference.

Constraints

  • Two EVS disks used to create the EVS replication pair have been created and belong to different AZs.
  • The types and capacities of the two EVS disks must be consistent.
  • If the DR disk has been attached to a server, the server must be stopped.
