Response¶
Parameter description
Parameter
Type
Description
replication
Object
Specifies the information about a replication pair.
For details, see Table 1.
Table 1 replication field description¶ Parameter
Type
Description
id
String
Specifies the ID of a replication pair.
name
String
Specifies the name of a replication pair.
description
String
Specifies the description of a replication pair.
replication_model
String
Specifies the replication mode of a replication pair. The default value is hypermetro, indicating synchronous replication.
status
String
Specifies the status of a replication pair. For details, see Replication Pair Status.
progress
Integer
Specifies the synchronization progress of a replication pair.
Unit: %
replication_status
String
Specifies the data synchronization status.
active: Data has been synchronized.
inactive: Data is not synchronized.
copying: Data is being synchronized.
active-stopped: Data synchronization is stopped.
attachment
Array of objects
Specifies the device name.
For details, see Table 2.
server_group_id
String
Specifies the ID of a protection group.
volume_ids
String
Specifies the ID of the disk used to create a replication pair.
priority_station
String
Specifies the current production site AZ of the protection group containing the replication pair.
source: indicates that the current production site AZ is the source_availability_zone value.
target: indicates that the current production site AZ is the target_availability_zone value.
fault_level
String
Specifies the fault level of a replication pair.
0: No fault occurs.
2: The disk of the current production site does not have read/write permissions. In this case, you are advised to perform a failover.
5: The replication link is disconnected. In this case, a failover is not allowed. Contact customer service.
created_at
String
Specifies the time when a replication pair was created.
The default format is as follows: ""yyyy-MM-ddTHH:mm:ss.SSSSSS", for example, 2019-04-01T12:00:00.000000.
updated_at
String
Specifies the time when a replication pair was updated.
The default format is as follows: ""yyyy-MM-ddTHH:mm:ss.SSSSSS", for example, 2019-04-01T12:00:00.000000.
record_metadata
Object
Specifies the SDR data of a replication pair.
For details, see Table 3.
failure_detail
String
Specifies the error code returned only when status of a replication pair is error.
For details, see the returned value in Error Codes.
Table 2 attachment field description¶ Parameter
Type
Description
device
String
Specifies the device name.
protected_instance
String
Specifies the ID of the protected instance to which the replication pair is attached.
Table 3 record_metadata field description¶ Parameter
Type
Description
multiattach
Boolean
Specifies whether the disk in a replication pair is a shared disk.
bootable
Boolean
Specifies whether the disk in a replication pair is a system disk.
volume_size
Integer
Specifies the size of the disk in a replication pair. Unit: GB
volume_type
String
Specifies the type of the disk in a replication pair.
The value can be SSD, SAS, SATA, co-p1, or uh-l1.
SSD: the ultra-high I/O type
SAS: the high I/O type
SATA: the common I/O type
co-p1: the high I/O (performance-optimized I) type
uh-l1: the ultra-high I/O (latency-optimized) type
The co-p1 and uh-l1 types of disks are used exclusively for HPC ECSs and SAP HANA ECSs.
The extreme SSD type is currently not supported.
