Managed Replication After Live Volume Swap Role
In the following diagram, a swap role has occurred so the secondary Storage Center is on the left and the primary Storage Center is
located on the right. The managed replication has moved to follow the primary volume.
Figure 54. Live Volume with Managed Replication Example Configuration After Swap Role
1. Server 2. Server IO request to secondary volume (forwarded to primary
Storage Center by secondary Storage Center)
3. Secondary volume (Live Volume) 4. Live Volume replication over Fibre Channel or iSCSI
5. Primary volume (Live Volume and managed replication) 6. Server IO request to primary volume over Fibre Channel or iSCSI
7. Server 8. Destination volume (managed replication)
9. Managed replication over Fibre Channel or iSCSI
Managed Replication Requirements
Each Storage Center that participates in the Live Volume and managed replication configuration must meet specific requirements.
• The primary and secondary Storage Centers (Live Volume) must be running version 6.5 or later and meet the Live Volume
requirements.
• The destination Storage Center (managed replication) must be running version 6.5 or later and meet the replication requirements.

Creating Live Volumes
Create a Live Volume to replicate a volume to another Storage Center while allowing servers to send IO for the volume to both Storage
Centers. This additional flexibility can be used to perform planned outages without interrupting volume availability.
