Hi All,
We have 2 nodes windows 2008 cluster, both nodes are active, 3 SQL 2005 instances were running on Node1 and 2 SQL 2005 instances were running on Node2, and both nodes can do failover automatically. Our network team will do some maintenances next week, so the heartbeat between 2 nodes will be lost about 1 min. We just want all SQL instances to be run on their original nodes during the maintenance. My question is, how can we prevent sql failover when the nodes lose communication. We do not want them to failover automatically. I did checked cluster configuration, Under each cluster SQL service, it has server name,disk drivers and other resources (SQL server instance and SQL server agent). I can right click each of them, choose property->advanced policies, then I can see possible owners (both nodes were ticked). If I choose SQL service 1 which is running on node1. Can I clear the check box for a Node (for example Node2), so this resource won't failover to the node (node 2). But I have to change all items under the cluster sql service (server name,disk drivers and other resources (SQL server instance and SQL server agent)).
Does anybody have any other recommendation?
Thanks
David
