Description:
How to check the current version of the Nutanix AOS installed in your cluster or on an individual node.
Solution:
For the cluster, log on to any Controller VM (CVM) using SSH and enter the below nCLI command:
nutanix@cvm$ ncli cluster version
The version is displayed in the following format: distro_name-version-stable (e.g. euphrates-5.6.1-stable).
You can also use the following nCLI command:
nutanix@cvm$ ncli cluster info
In the output of the above command, look for the "Cluster Version" field.
Log in to the Prism web console. Click the user icon on the right, and select About Nutanix.
The version displays in the following format: Version number (e.g. Version 5.6).
For versions 4.0 and later, the displayed output includes license information.
For node, log in to the node for which you need to find the AOS version.
You can use one of the following commands to check the version installed:
nutanix@cvm$ cat /etc/nutanix/release_version
nutanix@cvm$ tail -1 /home/nutanix/config/upgrade.history
The version will display in the following format: el6-release-distro_name-number-stable-md_hash (e.g. el7.3-release-euphrates-5.5.9.1-stable-a528xxxxxx - LTS).
The (optional) abbreviation “LTS” designates whether the version release is a Long Term Support (LTS) Release. If there is no LTS designation, then the release is a Short Term Support (STS) Release.
Note: You can also check the version before adding a node to an existing cluster.
