Disallowing Replications Between Storage Center Systems
Disallowing Replications Between Storage Center Systems
By default, Storage Centers accept replications from other Storage Centers. If the systems
can see each other via FC or configured iSCSI connectivity, you are allowed to define
replications between them (if properly licensed).

To disallow replications between systems
1 From the Storage Management menu, select Volume > Replication > Allow
Replications to/from Remote Systems. The Remote System window appears.
2 From the pull-down menu, select Not Allowed.
3 Click OK.
