On Windows, Failover Manager uses PowerShell to execute commands on remote hosts. The PowerShell remote execution uses Windows Remote Management (WinRM) to execute commands on a remote host.

You need to configure WinRM to accept remote requests on each host running an VMware Smart Assurance Manager (Domain Managers and Service Assurance Managers). Use PowerShell 3.0 or later.

Also, you need to include the hosts in the Active Directory domains or the PowerShell TrustedHosts list. Each VMware Smart Assurance Manager host needs to trust the Failover Manager host, and the Failover Manager host needs to trust each VMware Smart Assurance Manager host. Two methods are available:

  • The preferred method is to include the hosts in Active Directory domains.

  • If this is not possible, add the Failover Manager host to the TrustedHosts list on each VMware Smart Assurance Manager host, and add each VMware Smart Assurance Manager host to the TrustedHosts list on the Failover Managers host.
