CVM/Cluster Details

This screen appears in the PowerChute Setup wizard and the details entered here are used to connect to your Nutanix Controller Virtual Machine or Cluster. The recommended configuration is to connect to your Nutanix Cluster.

You can authenticate the connection to your Controller VM or Cluster using the following options:

Enter your CVM/Cluster IP address, Controller VM/Cluster password and AHV Host password. Both passwords must be set to connect to your Controller VM/Cluster. If the Nutanix AHV Host Password field is left blank in the PowerChute Setup wizard, the CVM/Cluster password specified will be copied to this field.
Enter your CVM/Cluster IP address, the SSH key file path and its passphrase, if available.

These connection settings can be edited later through the PowerChute UI in the Communication Settings screen.

If both authentication options are specified in the PowerChute Setup wizard, PowerChute will use the passwords to connect to the Controller VM/Cluster.

NOTE: You must use the "nutanix" user account credentials to connect to the Cluster/Controller VM. You cannot use Prism user account credentials to connect.

The SSH key file, if configured, must be located in the user_files folder, or a sub-folder, in the PowerChute installation directory. If the default installation directory was chosen during installation, this location will be:

C:\Program Files\APC\PowerChute\user_files for Windows systems
/opt/APC/PowerChute/user_files/ for Linux systems

NOTE: If you are upgrading to PowerChute v4.4, any SSH key files used in a previous version of PowerChute must be manually added to the user_files folder. If the key files are not added to the directory, you will see the below error in the Event Log:

ERROR: The ini contains an invalid value for ssh_keyfile_path in nutanixClusterDetails.

It is strongly recommended you validate your configuration after an upgrade.

In the Communication Settings screen in the PowerChute UI, if you wish to change your authentication method, PowerChute will erase your previous authentication details. For example, if you connected to your Nutanix Cluster using the passwords option in the PowerChute Setup wizard and you want to use a SSH key file instead, when the Path to SSH Key File field is edited and the changes are applied, PowerChute will erase your configured passwords.

If you are authenticating the connection to your Controller VM/Cluster using passwords, you can use the Check Nutanix AHV Host Details button in the UI to check if your AHV hosts are online and accessible.

NOTES:

If you do not specify a Nutanix AHV Host Password in the PowerChute Setup wizard, this field will be set to the password specified for Nutanix CVM/Cluster Password.

If you specify a Nutanix AHV Host Password, you must click the Apply button before you can check to see if your AHV hosts are online.
If the Nutanix AHV Host Password and the Nutanix CVM/Cluster Password are not the same, you cannot update the Nutanix AHV Host Password via the PowerChute UI. See Nutanix Troubleshooting.
