Hi there

Couple question about cluster especially for Active/Passive mode:
1) Let say if you are running inserting within a transaction. In the middle of it, we initiate the failover and switch from node 1 to node 2. What is happening with that query? From my understanding, it will roll back ... correct? How about for SQL2000, is the same behaviour?
2) How do I found in cluster when the node (resources) switch from one node to another? I know there is a cluster file called cluster.log but that info it's only holding 3 days information which I don't think keep any info about switch node.

No since sql restarted.

Check sql server log, it tells you when restarted sql but not necessary due to cluster failover.
