Managing vCenter License Keys through the Command Line: A Comprehensive Guide

As a vSphere administrator, managing license keys is an essential task to ensure compliance and maintain access to VMware's suite of features. While the vSphere Web Client provides a user-friendly interface for managing licenses, there are scenarios where command-line access is preferred or necessary. In this article, we'll delve into the process of managing vCenter license keys through the command line, focusing on the vcenter license key command line aspect.

Understanding vCenter License Keys

Before diving into the command-line management of vCenter license keys, it's crucial to understand the basics. A vCenter license key is a 25-character code provided by VMware that unlocks specific features and functionalities within your vSphere environment. These keys are used to activate and manage licenses for various VMware products, including vCenter Server.

Prerequisites for Command-Line License Management

To manage vCenter license keys through the command line, you'll need:

Using PowerCLI to Manage vCenter License Keys

PowerCLI is a powerful tool that provides a wide range of cmdlets for managing VMware products, including vCenter Server. Here’s how you can manage your vCenter license keys using PowerCLI:

To add a new license key using the command line:

Add-VMLicense -LicenseKey "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX"

Expected output: The system will confirm the license key, edition, and capacity.

Ditching the GUI: Mastering vCenter Licensing via Command Line

We’ve all been there: staring at that persistent orange banner in the vSphere Client, reminding us that our evaluation period is ticking away. While the point-and-click method works for a single instance, real pros know that automation is the only way to scale.

If you’re looking to bypass the HTML5 interface and handle your licenses like a DevOps ninja, this guide is for you. Why Go CLI?

Efficiency is king. Whether you’re deploying a fresh SDDC or rotating keys across dozens of environments, manual entry is prone to human error. Using the command line—specifically VMware PowerCLI—allows you to bake licensing directly into your post-deployment scripts. The Secret Sauce: PowerCLI Commands

To manage licenses from the terminal, you’ll first need to establish a session with your vCenter server. powershell vcenter license key command line

# Connect to your vCenter Connect-VIServer -Server "://yourdomain.com" -User "administrator@vsphere.local" -Password "YourSecurePassword" Use code with caution. Copied to clipboard 1. Adding the Key to the Inventory

Before you can assign a license, it must exist in the vCenter license manager's inventory. You can do this by tapping into the LicenseManager view: powershell

$licKey = "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" $licMgr = Get-View LicenseManager $licMgr.AddLicense($licKey, $null) Use code with caution. Copied to clipboard 2. Assigning the License to the Asset

Adding the key isn't enough; you have to tell vCenter to actually use it. This requires the UpdateAssignedLicense method. powershell

$licAssMgr = Get-View $licMgr.LicenseAssignmentManager $licAssMgr.UpdateAssignedLicense($global:DefaultVIServer.InstanceUuid, $licKey, $global:DefaultVIServer.Name) Use code with caution. Copied to clipboard Checking Your Work

Want to verify that everything stuck? Use these quick snippets to audit your status: View all keys: $licMgr.Licenses

Check specific host status: Get-VMHost | Select Name, LicenseKey Pro Tip: Automate at Scale

If you have a list of keys, you can wrap these commands in a foreach loop to license an entire fleet of ESXi hosts and vCenter instances in seconds. No more orange banners, no more manual clicking.

Managing vCenter License Keys via Command Line: A Comprehensive Guide

For VMware administrators, the vSphere Client is the standard go-to. However, when you’re managing headless ESXi hosts, automating deployments, or recovering a vCenter Server Appliance (VCSA) that has lost its web interface, knowing how to handle licenses via the command line is a lifesaver.

This guide covers the essential methods for managing vCenter license keys using the PowerCLI and the vCenter Appliance Shell (BASH). 1. Managing Licenses via VMware PowerCLI (Recommended)

PowerCLI is the most powerful tool for remote license management. It interacts with the VMware APIs and allows you to manage licenses across multiple vCenter instances simultaneously. Connect to your vCenter Before running any commands, establish a connection: powershell

Connect-VIServer -Server ://yourdomain.com -User administrator@vsphere.local -Password YourPassword Use code with caution. View Current Licenses

To see all license keys currently added to the vCenter inventory: powershell

Get-LicenseDataManager # Or more simply (Get-View LicenseManager).Licenses | Select-Object LicenseKey, Name, Total, Used Use code with caution. Add a New License Key

To inject a new license key into the vCenter license inventory: powershell licmgr --server <ESXi_IP> --username root info

$LicenseMgr = Get-View LicenseManager $LicenseMgr.AddLicense("XXXXX-XXXXX-XXXXX-XXXXX-XXXXX", $null) Use code with caution. Assign a License to vCenter

Just adding a key isn’t enough; you must assign it to the vCenter asset: powershell

$LicenseMgr = Get-View LicenseManager $LicenseMgr.UpdateLicenseUsage("vcenter-uuid-here", "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX") Use code with caution.

Note: You can find your vCenter UUID by running (Get-View ServiceInstance).Content.About.InstanceUuid. 2. Managing Licenses via VCSA Shell (BASH)

If you are logged directly into the vCenter Server Appliance via SSH, you can use the internal configuration scripts. This is particularly useful for "break-glass" scenarios. Using the vim-cmd (Limited)

While vim-cmd is primarily for ESXi hosts, it can sometimes be used within the vCenter shell to query local information. However, for vCenter-specific licensing, we typically use the vpxd-related tools. Querying the License via Postgres DB

Because vCenter stores its configuration in a PostgreSQL database, you can query the assigned license directly if the services are down:

/opt/vmware/vpostgres/current/bin/psql -d VCDB -U postgres -c "SELECT * FROM VPX_LICENSE;" Use code with caution. 3. The "Emergency" Method: ESXi Host Licensing

Often, users search for "vcenter license key command line" when they actually need to license the underlying ESXi host to get vCenter back online.

If your ESXi host evaluation has expired and vCenter won't start, use this on the ESXi host SSH:

vim-cmd vimsvc/license --set="XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" Use code with caution. To verify the change: vim-cmd vimsvc/license --show Use code with caution. 4. Automation Use Case: Python (pyVmomi)

For DevOps environments, you might use the pyVmomi library. The logic follows the PowerCLI method: Access the LicenseManager via the Service Content. Use the AddLicense method to add the string.

Use DecodeLicense to verify the features of the key before applying. Troubleshooting Common Errors

"License key is not valid for this product": Ensure you aren't trying to apply an ESXi Standard key to a vCenter Server Appliance. They are distinct license types.

"Permission Denied": If using PowerCLI, ensure your account has the "Global.Licenses" privilege in vCenter.

Expired Keys: If a key is expired, vCenter will enter a "License Expired" state, disabling features like vMotion and High Availability. Adding a new key via CLI will instantly re-enable these features. Summary Checklist Command snippet List Keys Get-View LicenseManager Add Key $mgr.AddLicense("KEY") Assign Key ESXi Shell vim-cmd vimsvc/license --set

By mastering these command-line techniques, you ensure that your virtual infrastructure remains operational even when the GUI is out of reach. | Task | Command | |------|---------| | List

Managing VMware vCenter licenses via command line is primarily achieved through PowerCLI, as there is no direct "license set" command within the standard vCenter Appliance (VCSA) bash shell or appliance shell. Managing Licenses with PowerCLI

PowerCLI is the standard tool for automating vSphere management. To update or add a license, you must first connect to your vCenter Server. 1. Add a New License Key to the Inventory

To add a license key to the vCenter license manager without immediately assigning it: powershell

$licKey = 'XXXXX-XXXXX-XXXXX-XXXXX-XXXXX' $licMgr = Get-View LicenseManager $licMgr.AddLicense($licKey, $null) Use code with caution. Copied to clipboard

Source Reference: vCenter assign license key - Powershell script. 2. Assign a License Key to the vCenter Instance

Once a license is in the inventory, you must assign it to the vCenter asset using its unique Instance UUID: powershell

$vCenter = Connect-VIServer -Server "://example.com" $licAssMgr = Get-View $licMgr.LicenseAssignmentManager $licAssMgr.UpdateAssignedLicense($vCenter.InstanceUuid, $licKey, $vCenter.Name) Use code with caution. Copied to clipboard

Actionable Guide: For a full script including credential handling, refer to Updating the VMware vCenter License Key using PowerCLI. 3. Assign a License to ESXi Hosts

While vCenter itself requires the UpdateAssignedLicense method, individual ESXi hosts managed by vCenter can be licensed more simply: powershell

Get-VMHost "HostName" | Set-VMHost -LicenseKey "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" Use code with caution. Copied to clipboard Retrieving License Information

To view current license details, such as expiration dates and CPU usage, you can use the following commands: View Host Keys: Get-VMHost | Select Name, LicenseKey.

Check vCenter Status: Get-VCLicense -Status (available in PowerCLI 6.5+) provides a summary of licensed vs. used CPUs. Summary of Key Commands PowerCLI Command / Method Add Key $licMgr.AddLicense("KEY", $null) Assign to vCenter $licAssMgr.UpdateAssignedLicense($uuid, "KEY", "Name") Assign to Host Set-VMHost -LicenseKey "KEY" View Keys Get-VMHost | Select Name, LicenseKey

Alternative: If you cannot use PowerCLI, you must use the vSphere Client GUI by navigating to Administration > Licensing > Licenses to manually add and assign keys. VCenter assign license key - Powershell script | PowerCLI

Use the licensing CLI utility:

/usr/lib/vmware-vmafd/bin/vecs-cli entry list --store LICENSES

Or use the newer vmafd library:

/usr/lib/vmware-vmafd/bin/vmafd-cli get-license --server-name localhost

Get-Cluster "HR-Cluster" | Set-Cluster -License (Get-VMLicense -Key "XXXXX")

Get-VMHost | Select-Object Name, LicenseKey | Export-Csv -Path "C:\licenses.csv"

Get-VMHost | Select-Object Name, @N="EvalDaysLeft";E=$_.LicenseState.EvaluationDaysLeft

First, remove assignments; then delete the key.

# Remove license from all entities
Get-VMHost | Set-VMHost -License "None"
# Remove the key from vCenter
Remove-VMLicense -LicenseKey "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" -Confirm:$false
