Hi All,
I have 2 vmanage clusters join in DR, each cluster consists of 3 vmanage, when viewed on the menu "Cluster Management" active-cluster looks normal but on standby-cluster an error message appears "Failed to list vManage Cluster".
I Have restarted nms via vManage CLI but the result is still the same.
Have you ever experienced this problem?
Please help.
I've run diagnostic in vManage CLI. the results are attached.
Thanks.
Adi :)
