Expanding EVS Disks in a Replication Consistency Group (Deprecated)

Function

This API is used to expand the EVS disks in one or multiple EVS replication pairs. In such an expansion operation, two EVS disks in one EVS replication pair are expanded together.

Note

The status and replication_status values of the replication consistency group remain unchanged before and after capacity expansion. When 200 is returned, the capacity expansion is complete.

If the expansion fails, contact technical support engineers to locate and rectify the fault. After the fault is rectified, expand the disks again.

If the capacities of multiple EVS replication pairs in a protection group are expanded, an error indicating incorrect capacity will occur after the capacity expansion.

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

Constraints
