Instructions

To add a new server to the UMS HA installation, follow the instructions in the order given:

...

Note
  • High Availability with IGEL UMS Load Balancers: All UMS Servers and UMS Load Balancers must reside on the same VLAN.

  • For High Availability (UMS HA) with IGEL UMS Load Balancers, network traffic must be allowed over UDP broadcast port 6155, and TCP traffic and UDP broadcast traffic over port 61616. For further port configuration, see IGEL UMS Communication Ports .

  • The network configuration on Windows Servers must have the TCP/IPv6 option enabled for UMS 12.

  • IGEL UMS HA installation with IGEL UMS Load Balancers is not supported in cloud environments like Azure / AWS as they do not allow broadcast traffic within their networks. The HA installation without IGEL UMS Load Balancers (as well as the Distributed UMS, see IGEL UMS Installation ) is, however, supported in cloud environments as of UMS version 6.10.
