5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
For a node to join a Nutanix cluster, it must have a hypervisor and AOS combination that Nutanix supports. AOS is the operating system of the Nutanix Controller VM, which is a VM that must be running in the hypervisor to provide Nutanix-specific functionality. Find the complete list of supported hypervisor/AOS combinations at https://portal.nutanix.com/page/documents/compatibility-matrixFoundation is the official deployment software of Nutanix. Foundation allows you to configure a pre-imaged node, or image a node with a hypervisor and an AOS of your choice. Foundation also allows you to form a cluster out of nodes whose hypervisor and AOS versions are the same, with or without re-imaging. Foundation is available for download at https://portal.nutanix.com/#/page/Foundation.If you already have a running cluster and want to add nodes to it, you must use the Expand Cluster option in Prism, instead of using FoundationNetwork requirementsWhen configuring a Nutanix block a set of IP addresses
Nutanix Move is a cross-hypervisor mobility solution to move VMs with minimal downtime. Move supports migration from the following sources to targets, where first platform being the source and second platform being the target. MOVE-where to where?From ESXi to AHV, Legacy ESXi to Nutanix ESXi,AHV to EC2, Azure to AHV, Azure to ESXi on Nutanix,Hyper V to ESXi on Nutanix,HyperV to AHV, HyperV to Nutanix on AWS. What can MOVE do for you?Migration of power on/off VMs,pause and resume migration,schedule the migration activity,centralized platform for migration between several clusters,schedule data-seeding for the virtual machines in advance and cut over to a new AHV cluster, cancel migrations, monitor the migration activity at granular level. Deployment of MOVEThe MOVE package is available in the downloads section of the portal and can be installed on AHV or ESXi. Move must be able to communicate with vCenter Server on port 443, ESXi hosts on 902 and 443, and AHV on 9440. The move package m
Although Prism is user friendly, it will be nice to know some commands that are useful for cluster management. Cluster status The cluster status or “cs | grep -v UP” command gives the status(up or down ) of all the CVMs and their services. Running this command is helpful when there are alerts in the prism about services being down on certain CVMs. Metadata ring The command “nodetool -h0 ring” shows if all the CVMs are a part of the metadata ring. Being in a metadata ring is essential for the CVM to be an active part of the cluster and handle its designated responsibilities. It is essential to run this command after every hardware replacement to make sure the node is back sharing responsibilities of the cluster. Health check Most of the problems in the cluster are easily diagnosed by the health check command “ncc health_checks run_all” At the end of every WARN/INFO/ERR/FAIL plug in we see a KB to further troubleshoot the issue. This check is essential to make sure if the cluster he
Most of our customers upgrade their infrastructure once every couple of months and this guide helps our customers understand how to upgrade and what to expect from the process. In older versions of AOS, upgrades were done using “one click” or “upgrade software”. With LCM available in newer versions, the upgrades are much simpler and straightforward. Here’s the documentation to understand pre-requisites of LCM and how LCM works:https://portal.nutanix.com/page/documents/details?targetId=Life-Cycle-Manager-Guide-v20:Life-Cycle-Manager-Guide-v20 The LCM works on one-node at a time and if the upgrade proceeds to the next node if the scheduled node is successful in upgrading to the target version. The LCM upgrade tasks can be monitored from “LCM” in Prism UI. There is essentially no downtime required for the user VMs during the upgrades. With regards to concerns about performance, it’s always best to schedule maintenance window for the upgrades, especially with the cluster with 1G NIC ca
