RecoverPoint for VMs "seed" procedure?
Hello,
Does EMC support a "seed" procedure for RecoverPoint for VMs? For example, if the customer has a 50 Mbps WAN pipe and needs to perform an initial sync of 40 TB of data, they would prefer to "seed" it locally at the same datacenter (high speed LAN), and then move the equipment to the DR site, and re-configure RP to perform "delta change" syncs from the "seeded" initial copy. This would involve re-IP'ing the vRPA cluster for the DR site when moving it to a new subnet. From a high-level perspective, this is the goal:
1) Set up Primary Site vSphere cluster at Datacenter A using Subnet A.
2) Set up DR Site vSphere cluster at Datacenter A using Subnet A (temporarily, for initial seeding).
3) Physically move DR Site vSphere cluster to Datacenter B and Subnet B, re-IP'ing everything.
4) Re-configure RP4VMs to perform an incremental synchronization across the WAN, sending only changed blocks since the first initial full sync.
Is this supported by EMC? Is this procedure documented anywhere?
Thanks,
Bill

Hi Bill,
Will the storage/datastores be moving too? As long as the target VMs, VMDKs remain the same, I don’t see why not.
You will have to update the vcenter IP which is registered in RPVM using admin CLI. Also, as a worst case, if you have to reconfigure CGs, make sure you select the existing Copy/replica VMs (instead of RPVM auto-creating new VMs) and in that case even though the process will be full sweep, only changed blocks will be transferred across the WAN.
Doing a local test before the move is a good idea including testing VC re-IP. Feel free to contact me offline if needed.

Thanks, we will definitely test it out beforehand. Everything will be re-IP'd, including the vRPA nodes, so I just wanted to make sure it was supported to re-IP every single component, and resume replication without needing to do a "full sync".

I would also test the re-IP locally - especially if you’re re-IP’ing VC, vRPAs and iSCSI network. You can keep them all in subnet A but move them to a different IPs. AFAIK, I do not believe we have tested this procedure before and that’s why I suggest you fully test it locally.
