introduction
In the previous two articles , we have discussed Configuring SRM folder mapping as well as resource mapping .
In this article , we will discuss SRM network mapping.
One of the important step in SRM inventory mappings.
Network mapping needs to configured properly. If you don’t get this configured correctly, the VMs that are powered on at the Recovery Site might not be accessible across the network.
SRM Network mapping can only be related to Virtual machine port groups.
You cannot map management network or VMkernel port groups
Here in network pioneers [pioneers.lab] for example : we have 6 port group , But only one port group for VM traffic , which called [ VM network ]
We recommend you to create the similar Port groups names . It will help you to easily configure the network mappings.
Configuring SRM Network Mapping
To configure the Folder mapping :
Login to your Protected site vCenter server VCSA-prod-155 using vSphere web client.
https://vcsa-prod-155.pioneers.lab/
Click on SRM plugin -> Select Protected site vCenter and Click on Create Folder mapping under inventory mappings.
Conclusion
The virtual machines would certainly boot and be configured the way they were configured in the production site with the same static IPs, etc.
However, keep in mind the virtual machine would need all the same network infrastructure in place before it would truly be able to communicate, including the same gateway and DNS server addresses.
Generally speaking, most recovery or DR sites are not running the same internal LAN subnet as exists for the production subnet as this would result in overlapping subnets and routing issues.
VMware’s Site Recovery Manager includes some really great functionality that helps to consider for the network differences that exist in the protected site vs the network configuration that may exist in the recovery site.
This allows SRM to reconfigure the recovered virtual machine (replicated virtual machine) with the corresponding network settings that are appropriate for the recovery site.
The solution is simply : SRM Network Mappings
As explained above .
