We have a three node active / active / passive Windows 2012 cluster.
One node contains a single instance (Role) of SQL Server, a second node contains two instances (Roles) of SQL Server. One of the instances is not being used yet.
I took the unused role off-line and in the process, the primary network took all three of the public IP addresses off-line.
If we take one role off-line, why would the other IP addresses also go off-line??
It apparently is a configuration issue but I cannot find any type of documentation in this.
