call datacenter.queryconnectioninfo for object test on vcenter server

Error: When you delete a cluster  in vCenter with out removing host you will be face an error “Call “Datacenter.QueryConnectionInfo” for object “Datacenter Name” on vCenter Server “vCenter server name” failed.

Cause: We should not remove cluster abruptly while hosts are configured to cluster.


1. Enter the host in maintenance mode which are not connected to vcenter server.

2. Then add the host in the vcenter server.

3. Exit the maintenance mode.

4. Then reconfigure cluster, if you abruptly removed or check with your requirements for cluster to those hosts.
