Quorum in Failover Cluster | How to Change Disk Witness in Quorum from one drive to other || Ms SQL

In the Windows Failover Cluster, we have two or more cluster nodes, and these nodes communicate with each other on the UDP port 3343. Suppose due to some unforeseen circumstances; nodes cannot communicate with each other. In this case, all cluster nodes assume that they need to bring the resources online. Multiple nodes might try to bring the same resource online at the same time, but it is not possible to do so. This situation is called a Split-Brain situation, and we never want to be in this situation. We might face data corruption issues in this case.

We can avoid a split-brain scenario in Windows Failover Cluster by bringing the resources on a single node. Windows cluster achieve this by implementing a voting mechanism. Quorum checks for the minimum number of votes required to have a majority and own the resources

What if you only have 3 nodes running a SQL availability group with no shared disks. There are two that are in one subnet and one that is in another subnet?

Hello, tysm for the video, I have a question, if my cloud witness is in Azure(storage account), do you know how I can find out within the cluster configuration, how to look at that resource to which I am connecting in Azure?
