A vRealize Automation IaaS DEM Worker that communicates with and collects data from Openstack or PowerVC must meet additional requirements, in addition to those for all IaaS Windows servers and DEMs in general.

All

In Windows Registry, enable TLS v1.2 support for .NET framework. For example:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

"SchUseStrongCrypto"=dword:00000001

Windows 2008 DEM Host

In Windows Registry, enable TLS v1.2 protocol. For example:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

Self-signed certificates on your infrastructure endpoint host

If your PowerVC or Openstack instance is not using trusted certificates, import the SSL certificate from your PowerVC or Openstack instance into the Trusted Root Certificate Authorities store on each IaaS Windows server where you intend to install a vRealize Automation DEM.
