Question

Dear Support,

Good morning, I encountered

"An attempt to connect to the cluster failed due to one or more nodes not responding to WMI calls. This is usually caused by a problem with the WMI infrastructure on the nodes"

from Primary Node of WSFC cluster Cluster_Primary.logSecondary showed Cluster healthy, operational DB AvailabilityGroup FailOver successful Secondary back to Primary but I cannot Connect the cluster from FailOver Cluster Manager for Primary.

Server = 192.84.27.151

DB AG EndPoint = 12.12.12.151

HeartBeat=10.10.10.151

Please assist. Thank you very much.

I think that WMI err means the primary’s cimv2 lost its rpc bind path to clussvc and u can bounce winmgmt + clussvc, it nudges a fresh rpc sess… if it still hangs, rebuilding the WMI repo usu clears the old rpc refs on that node.
