VNX Unified Multi Site Replication - 3 Nodes

Hi Guys ,

We have a requirement to implement a 3 node replication solution on VNX 5200 unified.

The current solution is :

VNX1 ---CIFS Replication----> VNX2

Failover works really well , back and forth etc.

Moving to :

VNX1 ---CIFS Replication----> VNX2

VNX1 ---CIFS Replication----> VNX3

This all works really well for replication and the R/O replica's. VNX3 is used a Backup provider and data mining R/O endpoint.

However in the event of DR or more often periodic failover testing , the replication solution is failed over from VNX1--- >VNX2

Can we have the replication automatic for VNX2 to then continue the replication to VNX3 ? when VNX2 is made primary ?

I can't setup a replication from VNX2 to VNX3 as the FS is read only when the replication is running from VNX1----> VNX2

We aren't using Replication Manager currently either.

Many Thanks

Neil
