Hello,
We are trying to setup a failover cluster using two agents installed on virtual machines. Could somebody share with us the best way to configure the IP addresses of these virtual machines before setting up the cluster? Currently the they have one IP address.
For instance, do we need two subnets for the corporate and acquisition networks or only one subnet is enough?
Thanks,
You can find most of the information in our docs: Configuring Failover | DataMiner Docs
It is recommended to have them in the same subnet to allow the use of a VIP which is assigned to the active DMA by DataMiner. This way you communicate directly to the active DMA by using the VIP. So every DMA has its own IP and the active one has additionally the VIP assigned by DataMiner. If you need two separate subnets, you can work with hostnames. It is more complex to configure (you need to configure DNS records). With hostnames you don't know if you are going to connect to the active or passive, but you will be redirected to the active one if you initially connected to the passive one (extra network latency).
I see that this question has been inactive for some time. Do you still need help with this? If not, could you select Michiel’s answer (using the ✓ icon) to indicate that the question is resolved?
