delete a replication pair - Elastic Compute Service - Alibaba Cloud Documentation Center

If a replication pair is no longer needed, you can delete the replication pair. This topic describes how to delete a replication pair.

Background information

When you delete a replication pair, take note of the following items:

When you delete a replication pair, data on the primary and secondary disks is not changed. After the replication pair is deleted, the secondary disk becomes writable and stores data that was replicated up until the last asynchronous replication. When you create a replication pair again for the primary disk and secondary disk, the previously replicated data on the secondary disk is cleared and a full replication must be performed to replicate all data from the primary disk to the secondary disk. Proceed with caution.
If a replication pair is added to a replication pair-consistent group, you cannot separately delete the replication pair. The replication pair can only be deleted after it is removed from the replication pair-consistent group. For more information, see Remove replication pairs.

Log on to the Elastic Block Storage (EBS) console.
In the left-side navigation pane, choose Enterprise-level Features > Async Replication.
In the upper-left corner of the top navigation bar, select a region.
In the replication pair list, find the replication pair that you want to delete and choose > Delete in the Actions.
In the message that appears, click OK.
When the replication pair is deleted, the secondary disk rolls back to the point in time when the last asynchronous replication was complete and drops all the data that is being replicated from the primary disk. The functionality limits are lifted from the secondary disk. You can attach the disk and read data from or write data to the disk.

If you delete a replication pair before your subscription bandwidth expires, submit a ticket to apply for a refund.
