secondary resource is overwritten immediately. Ensure that the data on the
secondary resource is no longer necessary or has been backed up. (default value)
– Data is inconsistent between the primary and secondary resources. After a
remote replication task is created, manually perform data synchronization.:
After the remote replication task is created, manually synchronize data on the
primary and secondary resources as soon as possible to ensure data consistency.
– The data on primary and secondary resources is consistent and data
synchronization is not required.: Ensure that the data on the primary and
secondary resources is consistent. If the data is inconsistent, the secondary resource
cannot be used to recover data or take over services from the primary resource
when the primary resource fails. As a result, data loss and service interruption may
occur.
4. Optional: Select Set the I/O timeout threshold for the secondary LUN and set
Timeout Threshold (second).
NOTE
If the data is not written into the secondary LUN successfully after the timeout you set, the remote
replication pair enters the Interrupted status.
The value range of timeout is 10 to 30 seconds. The default value is 30 seconds.
5. Click Next.
Step 7 Optional: Add the remote replication pair to a newly created consistency group.
1. Select Create a consistency group and add pairs to it.
2. Set Name and Description of the consistency group.
3. Click Next.
NOTE
You cannot set Timeout Threshold (second) when creating consistency groups. After the remote
replication is added to a consistency group, it inherits the configuration of the consistency group.
Step 8 Confirm the creation of the remote replication pair.
1. Click Next and view the configuration summary of the remote replication pair.
2. Click Finish to create the remote replication pair.
The security alert dialog box is displayed.
3. Confirm the information in the dialog box. Select I have read and understand the
consequences associated with performing this operation. and click OK.
The Execution Result dialog box is displayed, indicating that the operation succeeded.
4. Click Close.
