Are you looking to streamline your VMware ESXi upgrade process? vSphere Lifecycle Manager (vLCM) offers a powerful solution for managing ESXi updates efficiently. In this post, we’ll walk through the steps of performing a VMware ESXi upgrade using vLCM, specifically focusing on the ESXi 7.0 U3q update. We’ll also discuss the benefits of VLCM over manual methods and address some common questions about VMware support and licensing.

Preparing for the ESXi 7.0 U3q Update

Before diving into the upgrade process, it’s important to ensure your environment is ready. Here are the key steps to prepare:

1. Check your current ESXi version and build number
2. Verify vCenter Server compatibility
3. Use images instead of baselines for the upgrade
4. Assign the correct image to the cluster

In our example, we’re upgrading from ESXi build 22348164 to the latest 7.0 U3q build 23794027. It’s worth noting that using images for upgrades is becoming the preferred method, as baselines may be deprecated in the future.

VMware Host Remediation Process

Once you’ve prepared your environment, it’s time to start the remediation process. Here’s what to expect:

1. Initiate the remediation process through the vSphere client
2. Review and acknowledge any warnings about removed VIBs
3. Monitor the upgrade progress
4. Wait for the host to reboot after successful installation

During the upgrade, you may encounter warnings about removed VIBs. In our case, we saw warnings about an NFS v8i plugin and a CLI tool. These warnings are generally safe to acknowledge, but always double-check if they might impact your specific environment.

Benefits of Using vLCM for ESXi Patching

VLCM offers several advantages over manual “dirty upgrade” methods:

• Streamlined process for upgrading multiple hosts
• Incorporation of vendor add-ons, firmware, and drivers
• Reduced risk of human error
• Improved consistency across your environment

Many administrators still rely on manual methods, such as using SSH and ESXCli commands to update their hosts. While these methods can work, they’re more prone to errors and don’t offer the same level of integration and automation as vLCM.

VMware Support and Licensing Considerations

A common question that arises when discussing VMware updates is whether ongoing support is necessary. Here are some key points to consider:

• ESXi licenses are perpetual and don’t expire
• Support entitles you to contact VMware (now Broadcom) for assistance
• Updates are currently available without active support
• The support structure has changed, with some support now handled by resellers or distributors

It’s important to evaluate whether paid support meets your needs or if community resources and third-party support options might be sufficient. Keep in mind that while updates are currently available without active support, this could change in the future.

Best Practices for VMware vSphere Management

To maintain a healthy vSphere environment, consider the following best practices:

• Regularly patch and update your ESXi hosts
• Utilize VLCM for automated updates
• Keep your vCenter Server up-to-date
• Explore alternative support options, such as Experts Exchange

By following these practices, you can ensure your VMware environment remains secure, stable, and up-to-date.

Wrapping Up

Upgrading VMware ESXi using vLCM is a straightforward process that offers numerous benefits over manual methods. By leveraging vLCM, you can save time, reduce errors, and ensure consistency across your environment. As VMware continues to evolve, staying current with updates and best practices is key to maintaining a robust virtualization infrastructure.

FAQ (Frequently Asked Questions)

Do I need active VMware support to download and install ESXi updates?

Currently, ESXi updates for version 7.0 and 8.0 are available without requiring active support. However, this could change in the future, and it’s best to check with Broadcom or your reseller for the most up-to-date information.

What are the advantages of using vLCM over manual upgrade methods?

VLCM offers automated updates, incorporates vendor add-ons and firmware, reduces human error, and provides a consistent upgrade process across multiple hosts. It’s generally more efficient and reliable than manual “dirty upgrade” methods.

Are ESXi licenses perpetual?

Yes, ESXi licenses are perpetual and do not expire. However, active support is a separate consideration and may be necessary for certain benefits and assistance.

How often should I update my ESXi hosts?

It’s recommended to keep your ESXi hosts regularly updated to ensure security, stability, and compatibility with the latest hardware and software. The frequency may depend on your specific environment and requirements, but quarterly updates are a common practice in many organizations.

Can I use vLCM to update ESXi hosts without internet access?

Yes, vLCM can be used in environments without direct internet access. You can download update packages and create custom images that include all necessary components, then use these for offline updates through vLCM.
