Acropolis Hypervisor Configuration

The following commands help to configure Factory (Nutanix) loaded hypervisor called as Acropolis without reinstalling using Foundation process:

To configure IP Address:  root@ahv# vi /etc/sysconfig/network-scripts/ifcfg-br0 

ONBOOT="yes" 

NM_CONTROLLED="no" 

PERSISTENT_DHCLIENT = 1 

NETMASK="subnet_mask" 

IPADDR="host_ip_addr" 

DEVICE="br0" 

TYPE="ethernet" 

GATEWAY="gateway_ip_addr" 

BOOTPROTO="none“  (set as “static”)

DNS Entry:  root@ahv# vi /etc/resolv.conf

To List Ethernet Interfaces:  manage_ovs show_interfaces 

To verify the interfaces are assigned to br0:  manage_ovs --bridge_name br0 show_uplinks 

To Add 1gb Interface into br0:  manage_ovs --bond_name bond1 --interfaces 1g update_uplinks 

To Configure IP Address in CVM: ssh to CVM (ssh nutanix@192.168.5.254) and use sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0, finally reboot the CVM

To Create cluster:  1. cluster -s <cvm_ipaddress> (- - redundancy_factor=3 -> Only if RF3) create 

2.      cluster start

eg: cluster -s 192.168.0.10,192.168.0.11,192.168.0.12 create

To Set Cluster Name:  # ncli cluster edit-params new-name=cluster_name 

To Add DNS Server:  # ncli cluster add-to-name-servers servers="dns_server" 

To Add NTP Server: # ncli cluster add-to-ntp-servers servers="ntp_server" 

To Add External IP Address: # ncli cluster set-external-ip-address external-ip-address=‘Cluster IP Address”

To change CVM VLAN: change_cvm_vlan (SSH to CVM and run this command)

To Set Hostname: # vi /etc/sysconfig/network 

and /etc/hosts (Edit HOSTNAME entry)

To Configure IPMI for AHV:

root@ahv# ipmitool -U ADMIN -P ADMIN lan set 1 ipsrc static
root@ahv# ipmitool -U ADMIN -P ADMIN lan set 1 ipaddr mgmt_interface_ip_addr 

root@ahv# ipmitool -U ADMIN -P ADMIN lan set 1 netmask mgmt_interface_subnet_addr 

root@ahv# ipmitool -U ADMIN -P ADMIN lan set 1 defgw ipaddr mgmt_interface_gateway 

ipmitool lan set 1 plan id lan_id_number

To set VLAN ID for Acropolis Hypervisor (AHV)

ovs-vsctl set port br0 tag=host_vlan_tag 

Confirm Tagging by entering:

ovs-vsctl list port br0 

Cluster Initialization:
