Thanks Pedro_rocha. In fact I resolved the problem. I was trying to download a disk firmware in an ONTAP cluster from a remote VM using CLI. I gave to the network specialist the IP of the cluster management IP to grant access to the remote VM. When I further checked the logs (Splunk) I found out that the node1 IP is being blocked . So I gave then to the Network guy the IP of the 2 nodes, which solved the problem. Thanks again.
