# Expanding EVS Disks in a Replication Consistency Group (Deprecated)

#### Scenarios

Users can make an API call to expand the EVS disks in one or multiple EVS replication pairs of a replication consistency group. In such an expansion operation, two EVS disks in one EVS replication pair are expanded together.

The status and replication_status values of the replication consistency group remain unchanged before and after capacity expansion.

If the expansion fails, contact customer service to locate and rectify the fault. After the fault is rectified, expand the disks again.

EVS replication APIs have been deprecated. If you need to use the replication function, see Storage Disaster Recovery Service User Guide and Storage Disaster Recovery Service API Reference.

#### Prerequisites

- The status value of replication consistency group must be available, which means that the group status is normal.
- The replication_status value of the replication consistency group is not error.

#### Procedure

1. Make an API call to expand the EVS disks in one or multiple EVS replication pairs of the replication consistency group.

   For details, see Expanding EVS Disks a Replication Consistency Group in the Elastic Volume Service API Reference.
