To create Nutanix cluster

cluster -s 192.168.0.210,192.168.0.211,192.168.0.212 create

cluster start

ncli cluster edit-params new-name=yeahcls

ncli cluster get-name-servers

ncli cluster add-to-ntp-servers servers="time.google.com"

ncli cluster set-external-ip-address external-ip-address="192.168.0.220"

To Destroying a Cluster

Log into a Controller VM through SSH

cluster stop

cluster destroy

To set the CVM memory to 8GB

ssh to Node 192.168.0.200-202 as root

virsh list --all (so you can copy the CVM name)

virsh dominfo NTNX-2799c347-A-CVM (show CVM status)

virsh setmem NTNX-2799c347-A-CVM --size 8G (hot update, only)

virsh dominfo NTNX-2799c347-A-CVM (take effect immed.)

virsh shutdown NTNX-2799c347-A-CVM (have to be down to setmax RAM, a couple of mins~)

virsh setmaxmem NTNX-2799c347-A-CVM --size 8G

virsh start NTNX-2799c347-A-CVM

virsh dominfo NTNX-e313df13-A-CVM

To stop Nutanix Cluster

Log on to the Controller VM with SSH.

List all the hosts in the cluster.

acli host.list

Note the value of Hypervisor address for the node you want to shut down.

Put the node into maintenance mode.

nutanix@cvm$ acli host.enter_maintenance_mode 192.168.0.202 wait=true

Replace Hypervisor address with the value of Hypervisor address for the node you want to shut

down. Value of Hypervisor address is either the IP address of the AHV host or the host name. Specify

wait=true to wait for the host evacuation attempt to finish.

Shut down the Controller VM.

nutanix@cvm$ cvm_shutdown -P now

Log on to the AHV host with SSH.

Shut down the host.

root@ahv# shutdown -h now
