You can use virtual machine groups to define the startup order of virtual machines. vSphere HA follows this order when powering on the virtual machines in the group. In Region B, create the virtual machine groups defining the startup order of the cloud management virtual machines that are failed over from Region A.

You configure VM/Host groups and rules for the vRealize Automation virtual machines.

Procedure

  1. In a Web browser, log in to vCenter Server by using the vSphere Client.
    Settings Value
    URL https://lax01m01vc01.lax01.rainpole.local/ui
    User name administrator@vsphere.local
    Password vsphere_admin_password
  2. In the Hosts and clusters inventory, expand the lax01m01vc01.lax01.rainpole.local tree and expand the lax01-m01dc data center.
  3. Select the lax01-m01-mgmt01 cluster and click the Configure tab.
  4. Create a virtual machine group for the Microsoft SQL Server instance.
    1. In the left pane, navigate to Configuration > VM/Host groups and click Add.
      The Create VM/Host group dialog box opens.
    2. Configure the settings and click OK.
      Setting Value
      vRealize Automation IaaS Database
      Type VM Group
      Members vra01mssql01
  5. Repeat to this step to create the remaining VM/Host groups.
  6. Create a VM/Host rule to power on the vRealize Automation database before the vRealize Automation virtual appliances.
    1. In the left pane, navigate to Configuration > VM/Host rules and click Add.
      The Create VM/Host rule dialog box opens.
  7. Configure the settings and click OK.
    Setting Value
    Name SDDC Cloud Management Platform 01
    Enable rule Selected
    Type Virtual Machines to Virtual Machines
    The VM dependency restart condition must be met before continuing to vRealize Automation IaaS Database
    On restart for VM group vRealize Automation Virtual Appliances
  8. Repeat to this step to create the remaining VM/Host rules.
