## Configuring Site Replication

- Configure an alias in `mc` for each of the sites. For example if you have three MinIO sites, you may run:

```sh
mc alias set minio1 https://minio1.example.com:9000 adminuser adminpassword
mc alias set minio2 https://minio2.example.com:9000 adminuser adminpassword

		t.Fatalf("%s: <ERROR> %s", instanceType, err)
	}
	if len(buckets) != 2 {
		t.Errorf("%s: Expected number of bucket to be `%d`, but instead found `%d`", instanceType, 2, len(buckets))
	}

	// add three and test exists + prefix.
	err = obj.MakeBucket(context.Background(), "bucket22", MakeBucketOptions{})
	if err != nil {
		t.Fatalf("%s: <ERROR> %s", instanceType, err)
	}

	// 1. Initiate 2 uploads for the same object
	// 2. Upload 2 parts for the second upload
	// 3. Abort the second upload.
	// 4. Abort the first upload.
	// This will test abort upload when there are more than one upload IDs
	// and the case where there is only one upload ID.

	// construct HTTP request to initiate a NewMultipart upload.
	request, err = newTestSignedRequest(http.MethodPost, getNewMultipartURL(s.endPoint, bucketName, objectName),

	// Write the config input KV to history.
	err = saveServerConfigHistory(ctx, objectAPI, kvBytes)
	return
}

// GetConfigKVHandler - GET /minio/admin/v3/get-config-kv?key={key}
//
// `key` can be one of three forms:
// 1. `subsys:target` -> request for config of a single subsystem and target pair.
// 2. `subsys:` -> request for config of a single subsystem and the default target.
