Cluster Creation & Upgrades

Manual Cluster Creation

Create the cluster manually from a set of CVM IPs

cluster -s x.x.x.x,x.x.x.x,x.x.x.x create

Restart Genesis on all hosts (e.g. after imaging/creation issues)

cluster restart_genesis

Create 2-Node-Cluster

cluster -s node1_cvm_ip,node2_cvm_ip --redundancy_factor=2cluster_function_list=two_node_cluster create

 

1-Click Hypervisor Upgrade

Enable/disable automatic install of the downloaded hypervisor during a 1-click upgrade

cluster --host_upgrade enable_auto_install
cluster --host_upgrade disable_auto_install

AOS Upgrade

Check current host/AOS upgrade status

host_upgrade -s

Directory where downloaded upgrade packages (AOS, AHV, ...) land

/home/nutanix/software_downloads

Manually push an AOS upgrade to another CVM (run from the CVM that already has the new AOS version)

/home/nutanix/cluster/bin/cluster -u <new_node_cvm_ip> upgrade_node

Watch which node is currently being upgraded

while [ true ] ; do upgrade_status ; sleep 1 ; done
