Pre-requiste for ESXI Upgrade Need to enable both HA, and DRS https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-1D8B1384-59A4-41E2-AF05-697FC06D9EF9.html When vSphere HA performs failover and restarts virtual machines on different hosts, its first priority is the immediate availability of all virtual machines. vSphere HA uses the virtual machine's CPU and memory reservation and overhead memory to determine if a host has enough spare capacity to accommodate the virtual machine. After the virtual machines have been restarted, those hosts on which they were powered on might be heavily loaded, while other hosts are comparatively lightly loaded.In a cluster using DRS and vSphere HA with admission control turned on, virtual machines might not be evacuated from hosts entering maintenance mode. You must manually migrate the virtual machines off of the hosts using vMotion. This behavior occurs because of the resources reserved for restarting virtual machines in th
PRISM:Prism Central is the centralized management tool for administrator to manage and monitor multiple Nutanix clusters. Prism Central by itself is an appliance VM running on the Nutanix cluster and hence, runs distributed services similar to a CVM. Some of the features that enable a centralized management are Single Sign On to all Prism elements, performance monitoring analytics for monitoring performance, and many moreSSP:The Prism self-service portal (SSP) or Prism Self Service Administration, enables the consumers of IT infrastructure within an enterprise: individual users or teams such as development, test, and DevOps to provision and manage virtual machines in a self-service manner, without having to engage IT in day-to-day operations.CALM:Calm (Cloud Application LifeCycle Management) is a DevOps Automation Platform that models applications and integrates your teams, governance, and life cycle operations to manage your applications. It supports multiple platforms so that you ca

Anecdote by @Kiran Surya Nutanix users and administrator are often required to access the CVMs, Hypervisors and IPMIs through their IP addresses. The most commonly used method to look at the IP addresses of these three entities is through Prism Element, and going through the Hardware tabs. However, looking through the GUI can be time consuming since you are required to click on every Host to view the IP address details of all three components. It’s all the more cumbersome if you have a huge infrastructure, like say 24 Hosts. It would be ideal if there is an easier process to list all these pieces of vital information. I happen to use the following combination of characters to list all these three pieces of data, and needless to say the customers are delighted when they see me run this command: nutanix@NTNX-7B43JB2-A-CVM:10.171.154.127:~$ nutanix@NTNX-7B43JB2-A-CVM:10.171.154.127:~$ echo; set `ncli host list | grep Address | sed 's/^.*: //'`;echo -e " IPMI\t CVM\t\tHy
