Use the commands in the table below to change the Nutanix passwords from their default:
Term
Definition
AHCI
Advanced Host Controller Interface. A technical standard defined by Intel that specifies the operation of Serial ATA (SATA) host controllers in a non-implementation-specific manner in its motherboard chipsets (Intel, Inc., n.d.).
Boot volume
Refers to the partition on a hard disk containing the operating system and its dependent files.
CVM
Controller Virtual Machine - The Nutanix CVM is what runs the Nutanix software and serves all the I/O operations for the hypervisor and all VMs running on that host (Poitras, 2021).
Deduplication
A technique used for eliminating duplicate copies of data. Deduplication is used to ensure more efficient use of available storage.
HA
High-Availability. Used to improve uptime for a system. Nutanix HA is achieved with the use of redundant nodes that ensure continued uptime even in the event of a node failure.
HCI
Hyper-converged infrastructure. Software-defined IT infrastructure that abstracts away all elements of conventional systems, such as the hypervisor, storage, and networking. The end goal is a system that is simpler to operate and maintain.
Hypervisor
A piece of computer software that runs virtual machines.
Hypervisor, Type 1
A hypervisor that is installed directly onto a host server. A host server running a type 1 hypervisor is a dedicated virtualization host that cannot be used for any other purpose.
NVMe-based drives
Nonvolatile memory express. A storage access and transport protocol for flash and next-generation solid-state drives.

echo -e "CHANGING ALL AHV HOST ROOT PASSWORDS. Note - This script cannot be used for passwords that contain special characters ( $ \ { } ^ &)\nPlease input new password: "; read -s password1; echo "Confirm new password: "; read -s password2; if [ "$password1" == "$password2" ] && [[ ! "$password1" =~ [\\\{\$\^\}\&] ]]; then hostssh "echo -e \"root:${password1}\" | chpasswd"; else echo "The passwords do not match or contain invalid characters (\ $ { } ^ &)"; fi
This is a script that changes the node root password on all your nodes at once. Run this from any CVM in your cluster.
