VMware Cloud Foundation 5.2.1.1 Release Information

VMware Cloud Foundation 5.2.1.1 includes bug fixes and a new version of SDDC Manager.

You can upgrade to VMware Cloud Foundation 5.2.1.1 from VMware Cloud Foundation 5.2 or later.

Upgrading from 5.2.1:

SDDC Manager is the only component that requires an upgrade. See Independent SDDC Manager Upgrade using the SDDC Manager UI.

Upgrading from 5.2:

See Flexible BOM Upgrade in VMware Cloud Foundation. When selecting the target version for SDDC Manager choose the version listed in the BOM update table below.

Known issues:

In order to upgrade from 5.2 to 5.2.1.1, you must download the bundles for both SDDC Manager 5.2.1.0 and SDDC Manager 5.2.1.1.
The Bundle Management window in the SDDC Manager UI displays “VMware Cloud Foundation Update 5.2.1.0” instead of “VMware Cloud Foundation Update 5.2.1.1” for the 5.2.1.1 bundle. The description of the bundle correctly describes it as the upgrade bundle for 5.2.1.1. This is a cosmetic issue only and does not impact the upgrade.

VMware Cloud Foundation 5.2.1.1 contains the following BOM updates:

Software Component	Version	Date	Build Number
SDDC Manager	5.2.1.1	05 DEC 2024	24397777

Resolved Issues

The following issues are resolved in this release:

VMware Cloud Foundation 5.2 does not support the “License Now” option for vSAN add-on licenses based on capacity per tebibyte (TiB).
Remove unresponsive ESXi Host fails when SDDC Manager certificate does not have subject alternative name.

Upgrade Process

Take a snapshot or have a backup of SDDC Manager if anything goes wrong.

Update is downloading, should be ready within 10 minutes

Now that the upgrade is staged and the bundle has been automatically ingested you can start the upgrade!

The whole upgrade took – 20 minutes 22 seconds

Once your SDDC Manager is upgrade you may proceed to NSX and ESXi upgrades for this release, which the same upgrade process exists in my other blog posts.

VMware Cloud Foundation 5.2.1 – Upgrade Process & Troubleshooting Tips

by Tommy Grot October 9, 2024

written by Tommy Grot 6 minutes read

VMware has released a new version of its flagship product, VMware Cloud Foundation (VCF), with version 5.2.1. This upgrade brings exciting new features and enhancements to the table, offering improved functionality and performance for VMware users. In this blog post, we’ll discuss the key features of VCF 5.2.1 and provide some quick tips and tricks to get your upgrade process started.

What’s New

The VMware Cloud Foundation (VCF) 5.2.1 release includes the following:

Manage all SDDC certificates and passwords from a single UI: SDDC Manager certificate and password management functionality is now integrated in the vSphere Client to simplify and speed-up day-to-day operations. VCF users can now manage the certificates, integrated certificate authorities, and system user passwords from the Administration section in the vSphere Client.
Reduced Downtime Upgrade (RDU) support for vCenter: VCF users can now leverage vCenter Reduced Downtime Upgrade (RDU) to execute a vCenter upgrade. vCenter RDU is a migration-based approach to upgrading vCenter and reduces the vCenter downtime to less than 5 minutes.
NSX in-place upgrades for clusters that use vSphere Lifecycle Manager baselines: VCF users now have the choice to perform NSX in-place upgrade for clusters that use vSphere Lifecycle Manager baselines. In-place upgrades eliminate the need to place hosts into maintenance mode during the upgrade.
Support for vSphere Lifecycle Manager baseline and vSphere Lifecycle Manager image-based clusters in same workload domain: VCF users now have the flexibility to deploy and upgrade vLCM baseline and vLCM image-based clusters within the same workload domain.
Support for the “License Now” option for vSAN add-on licenses based on capacity per tebibyte (TiB): VCF users can now apply the vSAN TiB capacity license within the SDDC Manager UI to expand storage capacity for their workload domains and clusters. You can also use the “License Later” option to assign the per-TiB vSAN license key using the vSphere Client.
Set up VMware Private AI Foundation infrastructure from the vSphere Client: VCF users can leverage a new guided workflow in the vSphere Client to set up infrastructure for VMware Private AI Foundation and maximize the potential of NVIDIA GPU-enabled ESXi hosts. The workflow streamlines the set up process by centralizing configuration steps from SDDC Manager and vCenter into a single workflow.

Upgrade Process & Troubleshooting Tips

To disable the upgrade compatibility checks, follow the steps below:

SSH into SDDC Manager appliance with the vcf user and su to root.
Edit the file: /opt/vmware/vcf/lcm/lcm-app/conf/compatibility.flag
Update the property vcf.compatibility.controllers.compatibilityCheckEnabled to false
Save and close the file.
Restart Lifecycle Management by running the command: systemctl restart lcm

Edit the file: /opt/vmware/vcf/lcm/lcm-app/conf/compatibility.flag (Example Below)

After you have updated the flag to false from true, reboot LCM service.

systemctl restart lcm

Once you have executed the syntax above, go back to SDDC Web UI and refresh the page, you should see “Update Now” enabled an no more errors.

I ran a pre-check, its a preferred practice to verify pre-checks of any upgrade of VCF, to ensure that everything will upgrade smoothly.

Pre-check is success with no errors or warnings! Lets Upgrade!

Update Now – will start the SDDC Upgrade to the latest version: Example below

Now that SDDC Manager has upgraded successfully, – Elapsed Time : 19 minutes 28 second

Now, for the next portion of the upgrade – I ended up having a issue where the SDDC BOM was erroring out, that I have a compatibility issue, this is due to a previous async patch upgrade that was required to fix CVE’s so what you will need to do is go back to the same configuration file and switch it back to false, and reboot lcm service. The configurations file reverts back to true after the SDDC upgrade.

Error Message:

You cannot select this target version for the following reasons. Select a different target version to proceed.

Cannot upgrade to VCF version 5.2.1.0 for domain ab8cae17-5034-4e2a-a3b1-ae283608d9ed in a compatible way: not upgradable: VCENTER 8.0.3.00200-24262322 -> VCENTER 8.0.3.00300-24305161, NSX_T_MANAGER 4.2.0.2.0-24278654 -> NSX_T_MANAGER 4.2.1.0.0-24304122; not interopable: VCENTER 8.0.3.00300-24305161 -> SDDC_MANAGER 5.2.1.0-24307856, VCENTER 8.0.3.00300-24305161 -> ESX_HOST 8.0.3-24280767, VCENTER 8.0.3.00300-24305161 -> NSX_T_MANAGER 4.2.0.2.0-24278654, NSX_T_MANAGER 4.2.1.0.0-24304122 -> VCENTER 8.0.3.00200-24262322, NSX_T_MANAGER 4.2.1.0.0-24304122 -> ESX_HOST 8.0.3-24280767, NSX_T_MANAGER 4.2.1.0.0-24304122 -> SDDC_MANAGER 5.2.1.0-24307856

Now after you have updated the configuration and restarted LCM service, go back to the SDDC UI and you should see it allow you to proceed with upgrade.

Now once the upgrade is staged and ready you can execute the NSX upgrade, which is the first part of the upgrade. Lets start!

NSX Precheck –

Selection if you would like to upgrade only NSX edge clusters, for my deployment I upgrade all of NSX.

Cluster Selection –

Upgrade options –

Preferred practice – to run the pre-check of any upgrade to ensure compatibility and prevent upgrade issues.

Lets Upgrade!

After NSX has upgraded, you will be able to proceed to vCenter Server upgrade process. If you want to watch the detailed upgrade of NSX you will need to login to the NSX manager web UI and go to System -> Upgrade (here you will be able to watch what is happening during the upgrade of NSX)

Finally to the exciting portion of the upgrade, the Reduced Downtime Upgrade (RDU) is outstanding and flawless and smooth process. Lets begin!

Ensure you have backups and everything you will need incase of any emergency that you need to roll back if the upgrade has an issue.

Here we will setup a temporary static IP, if you have a DHCP that works also.

At this part of the the upgrade, the scheduler we can tell the vCenter to do a immediate or scheduled switch over of the new vCenter that has been built / upgraded.

Verify everything you configured is correct to your needs before hitting Finish!

Now we watch the upgrade!

Elapsed Time : 35 minutes 39 seconds

That is all! We have upgraded VCF 5.2 to 5.2.1 and this process was super smooth and ran into few snags which we talked about here in this blog post from the async patch throwing off the BOM and then repeating the steps for SDDC Upgrade and also vCenter / NSX upgrade. Stay tuned for more VCF 5.2.1 posts!

written by Tommy Grot 3 minutes read

Today’s blog post is about VCF and how it is a comprehensive cloud management platform that enables organizations to build, deploy, and manage private clouds. With the release of VCF 5.2, VMware has further enhanced the platform’s capabilities, making it an even more attractive choice for businesses looking to modernize their infrastructure. In this blog post, we’ll delve into the process of upgrading specific components in VCF 5.2, including ESXi and Image Management.

This will be a living blog post – Any Issues I encounter will be documented here!

PowerShell Script for VMware Cloud Foundation Bundle Management

Below I will walk you through on using the PowerShell Script which is provided for end-users to be able to safely and easily clean up bundles within their SDDC Manager.

Prepare System Requirements:
- Windows, Linux, or MacOS running PowerShell Core 7.3.0 or later.
- VMware PowerCLI 13.1 or later
- PowerVCF 2.3.0 or later
Download attached script.
Extract script, change to its directory.
Run script
- with parameters:
  - .\VcfBundleManagement.ps1 -user <SDDC_Manager_user> -server <SDDC_Manager_FQDN> -pass <password> -rootPass <root_password>
  - Where:
    - <SDDC_Manager_user> is the username to authenticate with SDDC Manager.
    - <password> is the password to authenticate with SDDC Manager
    - <SDDC_Manafer_FQDN> is the fully qualified domain name of the SDDC Manager
    - <root_password> is the password for the root user on the SDDC Manager appliance
- without parameters (script will ask for input parameters):
  - .\VcfBundleManagement.ps1
Select options from the displayed menu and press enter to run it.

Specify your SDDC Manager ->

Once connected with your SSO Account ( I used [email protected], but any administrative privilege account shall work as well)

Selecting #7 Will Delete all obsolete bundles which I had for VCF 5.1.1 and no longer needed them.

Detailed Storage usage of the SDDC Manager is provided by option #4

vLCM Upgrade Preparation

For the vLCM Portion of the upgrade, I encountered a issue where I could not proceed till I built a custom image with all the dell firmware’s and drives addon, due to the reason my previous version of ESXi had the Dell OEM drivers embedded.

Configure Update ->

Select your cluster(s) ->

Select your image, so for this part you will need to go into vCSA and prepare a image that is latest version, and ensure that all OEM drivers are updated.

Once image is created go to Image Management -> Import Image from your Management Workload Domain vCenter

It will take few minutes but once the import is complete for the vSphere 8.0 U3 version, then you will see it appear in the vLCM upgrade window.

Back at the vLCM upgrade window, assign the image(s) that you created earlier and click next.

Upgrading VMware Cloud Foundation 5.2 involves updating specific components like ESXi and Image Management. By following the step-by-step guides outlined above, you can ensure a smooth and successful upgrade process that takes advantage of the latest features and capabilities in VCF 5.2. Remember to always back up your configuration and data before upgrading, and plan for downtime accordingly. With these best practices in mind, you’ll be well on your way to modernizing your private cloud infrastructure with VMware Cloud Foundation.

Click Next -> After you have applied your custom image for vLCM Upgrade. Once the vLCM is complete then ESXi will upgrade and below you can specify the deployment orientation. If your servers support Quick Boot keep it enabled or even Live Patch.

Upgrade process is about to begin…

Upgrade in process!

Expanded automation: Streamline workflows with additional self-service capabilities for users and automated infrastructure provisioning.
Improved security: Strengthen data protection with advanced encryption options and role-based access controls. Utilizing Identity Federation Support with Microsoft Entra ID and also 3rd party authentication services or well known AD/LDAP or okta and ADFS.
Import an existing vSphere Infrastructure into your VMware Cloud Foundation infrastructure.

Here in this blog post we will go over many different topics but we will go in depth in future blog posts on other areas of VCF 5.2!

With the new VCF 5.2 you can import a standalone vSphere environment which it can be a new or existing one and let you manage its lifecycle through one single pane window through the SDDC Manager.

Flexible Deployments

Now you can deploy VCF in many different use cases, from a data center in the edge or even a air-gapped environment. Now in VCF 5.2 you have the flexibility to deploy as your heart desires!

Lifecycle Management

Now this is an exciting addition to VCF 5.2! We can upgrade SDDC Manager independently where before it was apart of the management workload domain, this provides a lot of flexibility where before some customers needed to stay on a specific version before it could get upgraded, it had to go through thorough tests.

Software Bill of Materials

Patch Individual Components using SDDC Manager

I made a great blog post on how to utilize the SDDC Manager Async Patch tool, well before it was a CLI driven automation utility where you would have to stage your commands and prepare for upgrading the indiviual products outside the Software Bill of Materials

The VMware SDDC Manager async patch tool allows you to upgrade individual products outside of the standard VMware Cloud Foundation (VCF) baseline. This tool can be used to upgrade products such as vCenter, NSX, and ESXi to newer versions without affecting the overall VCF deployment.
From My Blog Post Here

Offline Bundle Repo

Now, this is a improvement for Air-Gapped environments or secured environments where there is no internet connection, with hosting your own repo for all the upgrades for VCF this will be a game-changer where it will save time and re-downloading each bundle or all the bundles.

vSphere 8 u3 Update

Key highlights of this release include:

Ability to manage Kubernetes clusters independent of vSphere, offering greater flexibility and autonomy for hybrid and multi-cloud deployments.
Simplified management of TKG clusters through the vSphere web client, streamlining workflows and reducing administrative overhead.
Automated scaling of virtual machines (VMs) based on workload demands, ensuring optimal resource utilization and cost efficiency.
Support for scale-up and scale-down of CPU, memory, and vCPUs simultaneously, enabling efficient adaptation to dynamic workloads.

vSAN Stretched Cluster Support:

Expansion of vSAN to support stretched clusters across geographically dispersed locations.
Continuous data consistency and disaster recovery across sites, ensuring high availability and business continuity.
VM Backup and Restore:
Comprehensive snapshot-based backup of TKGs, enabling easy restoration and disaster recovery.

Keeping your vSphere Updated

This ensures the following:

Optimal infrastructure performance and efficiency.
Enhanced security and compliance.
Improved management and automation capabilities.
Support for modern workloads.
Access to continuous innovation and support.

But also, now we can patch vSphere environment much faster and without taking too many services down and causing unhappy customers. So, now with the new upgrade process the host enters a partial maintained mode where the host has existing workloads operating on it but no new workloads will migrate nor any new VMs or containers will get deployed on it till it gets upgraded.

Hardware Support

Protecting crucial workloads utilizing DPUs, (Data Processing Units) this provides high availability with active and standby states for workloads where if there is any outage that could occur the operations switch over to the standby DPU. Which this is a really neat addon for mission critical workloads that rely on DPUs!

Also even taking off the load from the primary DPU and being able to provide additional bandwidth by utilizing DPUs to provide double the networking throughput and keeping workloads always on.

Also, with Intel’s AI/ML Workloads, the Intel CPU Max Series is an whole new type of CPU where they have high bandwidth memory on the chip to accelerate AI/ML workloads by ensuring advanced security and reducing bottlenecks during high demands.

vSphere with Different Types of GPU Workloads

Now with this release, customers have the opportunity now to use different types of workloads on a single GPU, where it could be Artificial Intelligence or Machine Learning or even like utilizing graphics or VDI. This will help the GPU resources be shared among different deployments as well allowing customers to have the flexibility as they choose.

Security & Compliance

More Choices in Identity Management

TLS Ciphers allowing quicker implementation

STIG and PCI Compliance with easy to use hardening guides

VMware Cloud Foundation 5.2 is a groundbreaking advancement in your own private or hybrid cloud infrastructure management, offering a comprehensive suite of features and enhancements to empower you to build, deploy, and manage modern infrastructure with unparalleled efficiency and agility.

With intelligent automation, enhanced security, and innovative storage capabilities, VCF 5.2 provides a foundation for building resilient, adaptable, and efficient cloud-native environments.

How To Setup Ollama + OpenWebUI on VCF

by Tommy Grot June 7, 2024

written by Tommy Grot 4 minutes read

In this blog post, we will explore how to host your very own ChatGPT using the powerful combination of Ollama and OpenWebUI, all powered by VMware Cloud Foundation. By leveraging these cutting-edge technologies, you’ll be able to create a seamless and interactive chatbot experience that will impress your users. Get ready to dive into the world of AI and virtualization as we walk you through the steps to set up your own ChatGPT. Exciting times are ahead, so let’s get started on this journey together!

This walkthrough will only guide you through how to setup Ollama and Open WebUI – you will need to provide your own Linux VM, for my deployment I used Ubuntu 22.04.

Next blog post we will go into customizing and adding onto Ollama and OpenWebUI with for example Automatic1111 and Diffusion and Image Generation LLMs.

The Hardware:

2 x Intel Platinum 8158 3.0GHz 12 Cores
1 x Nvidia Tesla P40 24GB DDR5
1 x Dell PERC H740P RAID Card
4 x 32GB Samsung DDR4 2666MHz (128GB)
2 x 50Gb/s Mellanox Connectx-4 Data Traffic
4 x 10Gb/s X710 NDC for NSX Overlay
1 x Boss S1 w/ M.2 SSD for ESXi Boot
2 x 2000 watt PSUs
8 x 800GB SAS SSD – Capacity Storage
2 x 280GB Intel Optane Storage – Fast Storage

The Virtual Machine:

Deploy a Ubuntu or any choice of Debian distro if you want to utilize the commands I have apart of this walkthrough.
Enabling Hardware Device Passthrough for the GPU also apart of your VMX add the following in:

pciPassthru.use64bitMMIO=”TRUE”
pciPassthru.64bitMMIOSizeGB=”128″

Once the Virtual Machine is deployed, you will want to ensure that your Server or Desktop Hardware is prepared to have a GPU, in my Dell PowerEdge R740XD I have a NVIDIA Tesla P40.

The Specifications:

This will vary, for my initial deployment I setup 8 vCPUs with the Automatic CPU Topology enabled, but this will all depend on your use case, since I have powerful CPUs and lots of memory I can increase the resource allocation later on.

The Software:

Download & Install Ollama:

curl -fsSL https://ollama.com/install.sh | sh

Time to Shutdown The Virtual Machine and Pass Through the NVIDIA Tesla P40

With the above requirements satisfied, two entries must be added to the VM’s VMX file, either by modifying the file directly or by using the vSphere client to add these capabilities. The first entry is:

pciPassthru.use64bitMMIO=”TRUE”

Specifying the second entry requires a simple calculation. Sum the GPU memory sizes of all GPU devices(*) you intend to pass into the VM and then round up to the next power of two. For example, to use passthrough with 4 16 GB A2 devices, the value would be: 32 + 32 = 64, rounded up to the next power of two to yield 128. Use this value in the second entry:

pciPassthru.64bitMMIOSizeGB=”128″

Add Docker’s official GPG key:

sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

Add the repository to Apt sources:

echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

Next, we will install docker and all its dependencies:

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Now we will setup the docker container for Open WebUI to run, on port 11434 – Yeah the port number looks like (LLAMA haha)

docker run -d --network=host -v open-webui:/app/backend/data -e OLLAMA_BASE_URL=http://127.0.0.1:11434 --name open-webui --restart always ghcr.io/open-webui/open-webui:main

After you run the command above, then your webserver should start running – Open up your browser and login! You will be directed to setup a username / email. Once that is done, have fun and enjoy your own private AI!

Now, you will be presented the dashboard for your very own ChatGPT Privately Hosted!

Enjoy! 🙂

Depending on what LLMs you want to pull here is a example of how to do it via CLI

ollama pull aya

There we pulled aya LLM!

vCenter 8.0u2 Upgrade Issue vCHA – postInstallHook

by Tommy Grot April 11, 2024

written by Tommy Grot 2 minutes read

Have you recently attempted to upgrade your vCenter to version 8.0.2.00300 from 8.0.2.00100, only to be met with an unexpected roadblock in the form of VMware vCenter High Availability (vCHA)? Well, you’re not alone! In this blog post, we’ll dive into the common pitfalls and challenges that users face when trying to upgrade vCenter with vCHA enabled. We’ll discuss the potential causes of the failure, troubleshooting tips, and possible solutions to get your upgrade back on track.

What is vCHA?

vCenter High Availability (vCenter HA) protects vCenter Server against host and hardware failures. The active-passive architecture of the solution can also help you reduce downtime significantly when you patch vCenter Server

For this vCenter Release, there has been many other issues that end-users have seen from issues where time zone, or local host dns. But, for my issue it was vCHA!

Time zone not being set to ETC/UTC within VAMI or CLI
Local Host and DNS Resolution within /etc/hosts file
vCenter Server High Availability Service enabled but not configured – This was my issue!

Performing start operation on profile: ALL Service-control failed. Error: Failed to start services in profile ALL. RC=2, stderr=Failed to start vcha services. Error: Service crashed while starting.

The Cause – vCHA was set to Automatic Start Up and Not Configured

The Fix –

Either GUI or CLI can be utilized to fix.

Take a fresh snapshot
SSH into vCenter, if you are running VCF, then you will need to lookup your password with VCF Lookup_password Service:
Execute Command to see if the vCHA service is running –

Command Line

vmon-cli -s vcha

vmon-cli -S DISABLED -U vcha

After service is stopped, try to resume patch or revert snapshot and redo the steps above to ensure that the vCHA service is disabled.

GUI –

Log into VAMI, Go to Services ->
Select – VMware vCenter High Availability -> Set Start Up Type Manual ( still to verify execute the command above to disable and ensure it is disabled)

Once, rebooted or re-verted snapshot and all previous steps are completed, you should have a successful upgrade of your vCSA!

Decoupling or Redeploying VMware Aria Suite Lifecycle

by Tommy Grot March 31, 2024

written by Tommy Grot 1 minutes read

Are you looking to know how to decouple or need to re-deploy the Aria Suite Lifecycle Manager from VMware Cloud Foundation? Well, you’ve come to the right place!

Take a Snapshot of your SDDC Manager (Offline) and a snapshot your vCenter Server appliance.
Then SSH to your SDDC Manager and elevate to root

su

Below are the psql commands you will need to execute to remove the old vRSLCM entries.

psql -h localhost -U postgres -d platform -c "truncate vrslcm;"

psql -h localhost -U postgres -d platform -c "delete from vm_and_vm_type_and_domain where vm_type ='VRSLCM';"

As well as cleaning up the old Passwords, this will also remove the Life Cycle Suite from the Password UI.

psql -h localhost -U postgres -d platform -c "delete from credentialhistory where credential_id in (select id from credential where entitytype ='VRSLCM');"

psql -h localhost -U postgres -d platform -c "delete from credential where entitytype ='VRSLCM';"

Lets re-deploy through SDDC Manager!

After all is removed, you may restart the deployment, for the deployment you will be asked few questions on DNS, IP , and as well a Tier 1 Load Balancer, I used the next available IP address where i knew that the previous one was locked in and couldn’t clean it up, but after the deployment the old load balancer IP was cleaned up!

That’s it! Once you vRSLCM gets re-deployed re-run your Certificate generations from CSR and re-install the cert! Don’t forget to rotate your vRSLCM password but also enable password rotation to prevent any issues in the future.

VMware Cloud Foundation 5.1.1 – Release Notes

Lets start the Upgrade!

Take a snapshot of your SDDC Manager and your vCenter Server, ensure they are offline snapshots.

Login to your SDDC Manager, and you shall see new bundles appear, this is only true if you have a internet connected VCF stack. If you are in a offline deployment follow this other walk through i made on how to download bundles for VCF and other products.

Example of what you shall see when bundles are automatically downloaded into your SDDC Manager

Next before we upgrade – ensure you run a Pre-Check Under the Workload Domains you want to upgrade

The Pre-check will verify connectivity and password authentication with service accounts to all different appliances. Once the pre-check is done we will proceed to the next step which is to plan the upgrade!

My Pre-check had few errors, one of the major errors was related to VM/Host Affinity rules for certain VMs like domain controller, Aria Logs, Aria Operations, so I had to disable the rules for the upgrade to ensure that there is no error during deployment.

Disabled VM/Host Rules

Here you will see the Pre-Check Results, I had 5 errors which one of of them was storage capacity of the vCenter Server and then VM/Host Rules that were enabled that needed to be disabled to continue the upgrade.

Once Pre-Check has been completed, you will see that your workload domain will have Updates Available in the right side of the window as shown below.

Now we plan for the upgrade, this is a new addition which helps out the upgrade path and sees the source and target version along with being able to see what bundles or what products have been upgraded if you have utilized the Async Patch tool like in this blog post here.

Now, you will see that my vCenter Server and NSX have been upgraded that is due to the Async patch tool, I upgraded my VCF out of cycle of the main released to fix few issues and security vulnerabilities. So thus the Green check marks for NSX_T Manager and vCenter and ESXi.

Now, we will wait – this task is running in the background, you will in a moment see that the Download Bundles task(s) will be running.

After the binaries have been downloaded, staged and prepared. You will see that your workload domain that was once with updates available is now ready for upgrade.

Lets Start the upgrade! Ensure you have GOOD BACKUPS and/or SNAPSHOTS of the SDDC Manager and vCenter Server. If you do lets continue!

SDDC Manager is now upgrading itself, it will upgrade the core components as well as the drift update if it is needed.

Setup Common Appliance Platform
Validate Services Before Upgrade
Remove Packages Pre Upgrade
Update Necessary RPMs For Photon4 Upgrade
VMware Cloud Foundation Services and Platform Upgrades
Authenticate Common Appliance Platform
Update VCF Service and Platform rpms
Reboot SDDC Manager
Refresh Custom Certificates
Update SDDC Manager Appliance Version
SDDC Manager Deployment Drift
Run VCF Services and Platform upgrades Post Validation
Validate Services
Cleanup
Stop Common Appliance platform Service

After 16 minutes and 29 seconds, we have an upgraded SDDC Manager! Since my vCenter and NSX have all been upgraded the upgrade would of continued and all the hosts would have upgraded automatically minus few questions being asked during the deployment.

Successfully deployed VMware Cloud Foundation 5.1.1!
