Step 8
Confirm the creation of the remote replication pair.
1.
Check the remote replication pair information. If correct, click
Finish
.
The security alert dialog box is displayed.
2.
Read the content in the dialog box carefully, and select
I have read and understood the
consequences associated with performing this operation.
.
3.
Click
OK
.
The
Execution Result
page is displayed.
4.
On
Execution Result
page, check whether remote replication pair is created
successfully.
5.
Click
Close
.
The remote replication pair displays detailed information in the remote replication pair
list if successfully created.

3.7 Creating a Consistency Group
Remote replication can implement data backup and disaster recovery in the scenario where a
host writes data to a single or multiple independent primary LUNs. However, remote
replication cannot implement data backup and disaster recovery in the scenario where a host
writes data to multiple dependent primary LUNs. A consistency group ensures data
consistency of secondary LUNs of all remote replication pairs in the group at the same point
in time (for example, the data of all secondary LUNs are the data copy of its primary LUN at
3:00 PM today), therefore ensures the data availability of primary LUNs after disaster
recovery.
Prerequisites
l
The
Role
of the remote replication pair to be added into the consistency group must be
Primary
.
l
The remote replication pair to be added into the consistency group must be from the
same storage device.
l
The
Replication Mode
of the remote replication pair to be added into the consistency
group must be the same as the
Replication Mode
of the consistency group.
Precautions
l
If the remote replication pair is not in split status, the system will split the remote
replication pair first and then add it into the consistency group.
l
The consistency group does not support the remote replication pair whose resource type
is file system.
l
After the remote replication pair has been added into the consistency group, the remote
replication pair will function according to the replication properties of the consistency
group (the properties are
Recovery Policy
,
Speed
,
Data Transmission
,
Synchronization Method
, and
Interval
). Functions of the remote replication pair are
not relevant to its own properties.
