Having a problem pinging the virtual address on a Microsoft Cluster server.
This has just happened on a number of clusters. I can ping the physical address of the servers but the virtual part of the server does not reply.
The the virtual server address does not appear in the arp-cache athough shown on a trace on etherreal that the virtual server does reply to the arp request using the mac address of the phisical NIC.
Seemed to be working ok for a few years and stopped working for 3 clusters. No upgrades have taken place on the servers or switches (6500 using MSFC). Have spoken to Microsoft they keep saying it is the switches, But not sure why it would just be the virtual address that do not resond.
I have tried static arp entry and this worked ok, but when the cluster fails over it uses the other nics mac address so stops working so this work arround is not a long term it needs to be dynamic
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
