Follow these steps to configure host and VM groups:
- Select ESXi HA cluster > VM/Host Groups
- Configure host groups to allow proper grouping of ESXi hosts for R1 and R2 side of SRDF/Metro cluster. Such groupings will leverage the side of SRDF/Metro which is in its proximity for host selection of failover. If SRDF/Metro links are operational but the failure is due to an ESXi host, VMware HA will take place within the same group instead of switching over to the other side of the SRDF/Metro cluster.
- Similarly, configure a VM group so that VMs continue to run on ESXi host on the same side of the SRDF/Metro cluster if failover is due to a host issue.
