Remote Replication Concepts
FIGURE 32
Replication Data Path After T1 Takeover
After T2 is back online, a failback is performed on the T1 controller and it takes over its
resources. If replication updates of projects Blue and Green are in progress, they will be
canceled and can be resumed following the completion of the failback.
Then controller S2 is taken down for maintenance and the takeover performed on the S1
controller causes it to take ownership of all of the resources, including the interface required for
continuing replication of project Green. If a replication update of project Green is in progress, it
will be canceled and can be resumed following the completion of the takeover.
