at this moment, we have only one publisher/subscriber in our IP telephony solution. Next month, we want to give it some redundancy adding a new subscriber and creating a cluster with these two servers. I haven´t found any guideline about adding a new subscriber, does anyone know if there is a guideline about it?
Thanks in advance
Sure. Here you can find the guide lines (I'm assuming you have a cluster version 7.X):
Install Software from a DVD on a Subsequent Node
Apply a Patch During Installation of a Subsequent Node
Add a New Node to an Existing Cluster
Hope it helps, please rate if it does.
