change remote_replication split

change remote_replication split


The change remote_replication split command is used to split a remote replication task. During the split of a remote replication task, the primary resource synchronizes with secondary resources for the last time, then data synchronization stops between both resources.


change remote_replication split remote_replication_id=?






ID of a remote replication task.

To obtain the value, run "show remote_replication unified".



Usage Guidelines

  • Before running this command, ensure that the selected remote replication task is exactly the one you want to split.
  • You cannot split a remote replication task that has been added to a consistency group. In this condition, you must remove the remote replication task from the consistency group before you can split the task.
  • Exercise caution when you attempt to split an asynchronous remote replication task whose primary and secondary resources are in the "initial synchronization" state or to split a synchronous remote replication task whose replication pair state is "synchronizing", because both attempts may cause data loss on employed secondary resources.
  • After you split the primary and secondary resources for a remote replication task, the data of the secondary resources will be consistent with that of the primary resource when it was split. A secondary resource is available to serve as a backup of the primary resource only when the status of the secondary resource is "consistent" or "synchronized".


To split remote replication task "9747215445131264", run the following command:

admin:/>change remote_replication split remote_replication_id=9747215445131264 
DANGER: You are about to split the primary resource from the secondary resource in remote replication. This operation causes the data on the secondary resource to become inconsistent with the data on the primary resource. 
Suggestion: Before you perform this operation, determine whether the split is necessary. 
Have you read danger alert message carefully?(y/n)y 

Are you sure you really want to perform the operation?(y/n)y
