Before you can create a VM-Host affinity rule, you must create the host DRS group and the virtual machine DRS group that the rule applies to.

About this task

For a cluster of virtual machines on one physical host, create one host DRS group that contains both the ESXi hosts. For example, HostGroup_1 contains ESXi_HOST_1, ESXi_HOST_2.

For a cluster of virtual machines across physical hosts, create one host DRS group that contains all the ESXi hosts. For example, HostGroup_1 contains ESXi_HOST_1 running MSCS_VM_1, ESXi_HOST_2 running MSCS_VM_2 …... ESXi_HOST_5 running MSCS_VM_5 and ESXi_HOST_6 as a standby host.

Procedure
