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,
As this question has now been inactive for a very long time, I will close it. If you still want more information about this, could you post a new question?
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).
Hi Michiel,
Thanks for your reply.
Based on you reply I believe having the below scenario would work well, right?
DMA1:
corporate 10.10.10.1
acquisition 10.10.10.31
DMA2:
corporate 10.10.10.2
acquisition 10.10.10.32
VIPs:
corporate 10.10.10.3
acquisition 10.10.10.33
In this example, both the corporate and acquisition IPs are in the same network. The acquisition IPs can be reached by any machine in the network and it is not isolated as they are meant to be when configuring them on physical machines using a cross cable.
Sorry for the late reply, did not notice your message as it was posted as a new answer. If you have no need to split corporate and acquisition traffic, you can also only configure one IP address (corporate) instead of both. DataMiner will connect to other IP addresses based on the routing table of the server, so could be that even if you configure two IFs that everything is going through the same.
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?
