What is the procedure for converting fibre connection for CRR to WAN connection?

I assuming you are referring to sending the replication data across Fibre Channel between your sites.  Are you talking about modifying an existing environment, or is this a new deployment?

Assuming you have IP connectivity between sites, there's no need for running remote replication over FibreChannel, you just need to ensure that the WAN ports on your appliances are able to communicate to each other.

Hi Misterodd,

Assuming you are a 4.x RP version and have an already existing replication going on FC and want to change replication over to WAN, First a checklist to ensure a smooth transition:

1- Check MTU between sites need to set MTU correctly in case of using VPN between sites etc..

2- We prefer WAN and LAN be in seperate subnets for ease of routing the packets and isolating network issues.

3- Need to add a routing on each Site to the other Site WAN network ID to add a routing rule specifically for the WAN interface eth0.

4- Review the Security guide of your RP version to make sure all ports RP will need are not being blocked or manipulated by firewall or Proxy.

5- NAT is not supported.

6- If using Sync replication need to ensure latency on WAN wont exceed 4 ms round time trip if not so might hit perfomance issues and need to re-consider Async replication instead.

7- Of course we are speaking of Physical RPAs and not vRPAs.

Now the steps are easy provided you have configured  IP correctly and configured route correctly on each RP cluster inside the RP system,

1- Login as boxmgmt to cluster Site IP via ssh of one of the RP clusters involved preferably the source cluster or Prod cluster

2- Choose option 4 "Cluster operations"

3- Choose again option 4 " Configure connection types to other clusters in the system"

4- this option will take you through a wizard to specify type FC or IP and the other site connection with.

5- if all is ok and WAN communication can be established it should change successfully.

Thx,

MAG

Thanks for your input, it has been very helpful...

Hi,

1. When converting remote replication from FC to IP, ensure that the proper IP addresses and Gateways are defined at each cluster and that you’re able to perform a ping test from each site to the remote site. When performing a ping test using the boxmgmt user via the Installation Manager menu, issue the following command though the internal command option using the WAN interface eth0 as follows:

· ping -I eth0

2. Ensure that all required network ports are opened as specified in the RecoverPoint 4.x Security Guide .

3. After validating IP connectivity between the clusters, detach each RPA from the cluster using the Cluster operations -> Detach RPA from cluster option using boxmgmt.

4. Modify connection type using the Configure connection types to other clusters in the system -> Configure cluster connection types option using boxmgmt.

5. Attach the RPA back to the cluster (I would recommend performing steps 3 – 5 on parallel nodes, i.e. RPA1/RPA1, RPA2/RPA2 etc).

6. Repeat for the other RPAs in the cluster.
