Hello team,


I have a challenge. The customer has a GAD environment. Active active. Quorum disk is at primary location.

They have a vmware cluster named cluster-esx10 this cluster has esx hosts. On primary and sedundary location. And multiple luns mapped. These luns are have GAD-PAIR status.

Now it comes. Customer has a new esx cluster called cluster-esx40. This cluster also has hosts at both locations, and have this cluster in use. The old and new cluster have different host_groups on CL3-A and CL4-A.


In Ops Replication there is a data flow and node named cluster-esx10. and use a policy GAD.

All volumes are connected to this data-flow.

However, the old cluster esx10 has been reused and has retained two LDEVs (luns) from the old cluster. The other LDEVs (luns) have been transferred to the new cluster "cluster-esx40" now I want ops protector to be set up in such a way that there will be a new dataflow and node with LDEVs that are mapped to those clusters.


I don't want the GAD volumes to have to be rebuilt from scratch.


What is the correct and/or best way to achieve this.

I'd love to hear your hints and tips.


Ps, additional problem is that customer is still using outdated version ops center.


Sincerely, Pieter Visser

Hi Pieter,
  I think what you are saying is as follows:
  • the old esx-10 cluster is only using 2 LDEVs
  • the new esx-40 cluster is using another group of LDEVs
  • the GAD contains all of the LDEVS that used to be used by esx-10
 Is this correct?
