NOTE
When you create a remote replication task using the storage resources created based on an application,
all available LUNs of the application are displayed in
Primary Resource
. For details about how to
create storage resources based on applications, see
Creating Storage Resources Based on
Applications
in the
OceanStor V3 Series V300R006 Basic Storage Service Guide for Block
. For
OceanStor 2000 V3 series (excluding 2600 V3 Video Surveillance Edition and 2800 V3), 5000 V3
series, and 6000 V3 series, you can configure the storage resources created based on applications. For
OceanStor 18000 V3 series, the storage resources created based on applications are not displayed when
you create a remote replication pair, because this type of storage resources is not supported by
OceanStor 18000 V3 series.
3.
In the primary resource area, select the desired primary resource.
4.
From the
Remote device
drop-down list, select the remote device where the secondary
resource resides.
NOTE
If no remote device exists, click
Add
to add one.
5.
In the secondary resource area, select the desired secondary resource.
6.
Click
Add to Pairs
.
Add the pair of the primary and secondary resources to
Pairs
.
7.
Click

.
Step 6
Set properties of the synchronous remote replication.
1.
From the
Speed
drop-down list, select the desired speed for synchronizing data from the
primary resource to the secondary resource.
–
Low
: When the speed is set to low, remote replication will take a long time. This
value is applicable to scenarios where the service load is heavy. The speed is
normally from 0 to 5 MB/s.
–
Medium
: When the speed is set to medium, remote replication will take a relatively
short period. This value is applicable to scenarios where the service load is heavy.
The speed is normally from 10 to 20 MB/s. (default value)
–
High
: When the speed is set to high, remote replication will take a short period.
This value is applicable to scenarios where the service load is relatively light. The
speed is normally from 50 to 70 MB/s.
–
Highest
: When the speed is set to highest, remote replication will be complete in
the shortest period. This value is applicable to scenarios where the service load is
light. The speed is normally above 100 MB/s.
2.
In
Recovery policy
drop-down list, select whether the remote replication pair
automatically synchronizes data or not after internal I/O errors of a remote replication
task are rectified or the replication link is up.
–
Manual
: The pair enters the
To be recovered
state. You need to manually
synchronize the data from the primary resource to the secondary resource in the
pair.
–
Automatic
: The pair enters the
Synchronizing
state. The system will automatically
synchronize the data from the primary resource to the secondary resource in the
pair. (default value)
3.
Select the initial synchronization method of the remote replication.
–
Data is inconsistent between the primary and secondary resources. After a
remote replication task is created, the system automatically performs data
synchronization.
: After the remote replication task is created, the data on the
