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
1 Browse to the cluster in the vSphere Client.
2 Click Configure.
3 Under Configuration, select VM/Host Groups and click Add.
4 In the Create VM/Host Group dialog box, type a name for the group (for example, HostGroup_1).
5 Select Host Group from the Type drop down box and click Add.
6 Click the check box next to a host to add it. Continue this process until all desired hosts have been
added.
7 Click OK.
Set up VM-Host Anity Rules for DRS Groups (MSCS)
Create VM-Host affinity rules to specify whether the members of a selected virtual machine DRS group
can run on the members of a specific host DRS group.
Prerequisites
Create virtual machine DRS groups that contain one or more MSCS virtual machines as described in
Create a Virtual Machine DRS Group (MSCS).
Create host DRS groups that contain one or more ESXi hosts, as described in Create a Host DRS Group
(MSCS).
Procedure
1 Browse to the cluster in the vSphere Client.
2 Click Configure.
3 Under Configuration, select VM/Host Rules and click Add.
4 In the Create VM/Host Rule dialog box, type a name for the rule.
5 From the Type menu, select Virtual Machines to Hosts.
6 Select the virtual machine DRS group and the host DRS group to which the rule applies.
For example, select VMGroup_1 and HostGroup_1.
7 Select Must run on hosts in group.
