Failover Cluster: LowerQuorumPriorityNodeID 1 or 0

Hi,

In case of split scenario one site supposed to stay up. There is "LowerQuorumPriorityNodeID" to set on a node. Situation:
28368-situation.jpg



If I understand this correctly, if site a is to stay up after "split" - one of the nodes in site b should be set to LowerQuorumPriorityNodeID=0. Is this right?
Thanks!

Hi ,

You can assign the LowerQuorumPriorityNodeID cluster common property to a cluster node in the secondary site so that the primary site stays running. Set this property on only one node in the site.

"1" is the example node ID for a node in the site that you consider less critical:

 (Get-Cluster).LowerQuorumPriorityNodeID = 1

In your case, if you want site A to stay up after "split", you should set LowerQuorumPriorityNodeID to Node4 or Node5 or node6's node ID.

For example, if the node iD of Node 4(in site B)=4. Then you should run the following command:

 (Get-Cluster).LowerQuorumPriorityNodeID = 4

For more details, please refer to the following link:

Hope this can help you understand better. If there is anything unclear please feel free to let me know.

Best Regards,
Candy

@CandyLuo-MSFT So according to the article (Get-Cluster).LowerQuorumPriorityNodeID = node id, not settings like 0 or 1. This is interesting because perhaps all other attributes have either 0 or 1, or 0,1,2 or some other combination of it. (Get-ClusterNode –Name "Node1").Id should give us id of a node we "consider less critical". It has nothing to do with on/off stuff. Example:
29426-example1.jpg

Is this right? Thanks for the article.
