Every Nutanix Cluster would have a Cluster IP configured to access Prism (Management Pane of Nutanix). # Or run from CVM and change for all hosts in cluster: hostssh "ovs-vsctl set port bond0 bond_mode=active-backup" Active-backup bond mode is the simplest, easily allowing connections to multiple upstream switches without any additional switch configuration.

Planning vs. VCENTER: Open console to CVM; CVM: ncli host ls | grep -C7 [IP address of CVM] ==> to find node_id (the node_id is the number behind the ::) Enable to set the CVM host to either ignore or explicitly restrict v1 and v2 snmp based connections. nutanix@cvm$ allssh manage_ovs – -bridge_name br0 – -bond_name bond0 – -interfaces 10g update_uplinks You may have to do this per host via KVM if this breaks the connection because of removing the 1Gb link from the bond. Warning. Login to CVM #ncli -h true, which actually shows hidden commands for us. ncli host ls | grep -C7 [IP address of CVM] If the new/changed NTP server is not listed in the output of the above command then check genesis.out for problems grep -i ntp data/logs/genesis.out 8. Added an allowed port mapping for 9940 to the PRISM Central Appliance on my internal router/switch/firewall. Nevertheless, whatever the Prism GUI lacks in functionality is almost always available via ncli commands. nutanix@PE_CVM$ nuclei remote_connection.reset_pe_pc_remoteconnection Re-run ncli multicluster get-cluster-state to verify the connection state.
