Hello,
We have a 2 node active/passive SQL cluster setup and recently have been having really strange intermittent problems with the public side interface on t
he passive node.
Around 4-5 times a day the passive node will complain with a warning that it
lost communication with the public interface of the active node followed by
a few more warnings about the public side interface going down.
The active node shows these occurrances in it's event log as losing public network connectivity to the passive node.
I don't think this is an issue with the network card or cabling. I was logg
ed on the passive node during one of its public side interface outages and it was still able to ping the active node by name and the virtual SQL server
but it was not able to ping the cluster name. All 3 are pointing to the same public side interface on the active node.
Any advice on what is causing these problems and the solution would be greatly appreciated.
Thanks in advance,
Matt.
