Cloud Foundation, NSX

VMware Cloud Foundation (VCF) has revolutionized data center virtualization by seamlessly integrating compute, storage, and networking components. In a VCF environment, the NSX platform provides crucial software-defined networking capabilities. At times, removing NSX edges becomes necessary due to infrastructure changes, optimization efforts, or other reasons. To simplify this process, VMware has introduced the NSX Edge Removal Tool. In this blog post, we will explore how this tool can streamline the removal of NSX edges in a VCF environment while preserving dependencies.

Understanding the NSX Edge Removal Tool

The NSX Edge Removal Tool is a powerful utility developed by VMware to assist with removing NSX edges in a VCF environment. It simplifies the edge removal process and ensures the preservation of critical dependencies. Let’s delve into the steps involved in using this tool effectively.

Step 1: Preparing for NSX Edge Removal

Before utilizing the NSX Edge Removal Tool, it is crucial to thoroughly understand your VCF environment and identify all dependencies associated with the NSX edges you plan to remove. Review your network configuration, firewall rules, security policies, and any applications or services relying on the edges. This assessment will help you plan and execute the edge removal process more efficiently.

Step 2: Installing and Configuring the NSX Edge Removal Tool

To begin, download the NSX Edge Removal Tool from the VMware website. As of the writing of this blog the latest download can be found here. Follow the installation and configuration instructions provided by VMware to integrate the tool into your VCF environment seamlessly. Ensure that you have the necessary credentials and permissions to access and modify the NSX edges. In my case I downloaded edge_cluster_cleaner_0.27.tar.gz and transferred it to the server.

Step 3: Running the NSX Edge Removal Tool

Once the tool is installed and configured, it’s time to execute the removal process. Launch the NSX Edge Removal Tool and provide the required information, such as the NSX Manager IP address, credentials, and the specific edges you wish to remove. The tool will validate the environment and dependencies, ensuring a safe removal process. ex ./remove_edge_cluster.sh --cluster WLD1-edge-cluster --workload SDDC-MGT --user [email protected]

Step 4: Verifying and Analyzing the Dependency Report

After executing the removal process, the NSX Edge Removal Tool generates a dependency report. This report provides crucial insights into the dependencies associated with the removed NSX edges. Review the report thoroughly to understand any potential impacts on your network infrastructure and applications.

Step 5: Addressing Dependencies and Network Adjustments

Based on the generated dependency report, it’s essential to address the identified dependencies and make necessary adjustments to your network configuration. Collaborate with network administrators, application owners, and other stakeholders to migrate the dependencies to alternative network resources. Update firewall rules, adjust routing configurations, and ensure seamless connectivity for critical services.

Step 6: Post-Removal Validation and Testing

After addressing the dependencies and making the required adjustments, perform comprehensive validation and testing to ensure that the network connectivity and critical services are functioning optimally. Monitor the network closely for any abnormalities or performance issues, and address them promptly.

Conclusion

The NSX Edge Removal Tool provides a streamlined approach to removing NSX edges in a VMware Cloud Foundation (VCF) environment while preserving critical dependencies. By following the steps outlined in this blog post and utilizing the tool effectively, you can simplify the edge removal process and ensure the smooth operation of your VCF environment.

Downloading specific VCF bundles via CLI

Jul 05, 2023
/
Cloud Foundation

I wanted to reuse my VCF downloaded bundles on another SDDC Manager system so that i wont have to download it from internet again. I found an easy guide here in the VMware documentation. My goal was to download the specific bundle once and upload it on other SDDC Managers.

The first command from SDDC manager was to list the bundles. The lcm bundle transfer utility can be found in /opt/vmware/vcf/lcm/lcm-tools/bin

./lcm-bundle-transfer-util -du ${depotUser} -l -p ${product_version}

I replaced the ${depotUser} with my vmware email address and ${product_version} with the version of the VCF product i wanted to install in my case 5.0.0.0. I was greeted with a list of bundle IDs and the specific component that it was for:

Enter Myvmware user password:
Validating the depot user credentials...

Bundle         Product  Bundle Size  Components
               Version  (in MB)
bundle-80035   5.0.0.0  599.5 MB     ESX_HOST-8.0.1-21813344
bundle-80031   5.0.0.0  10089.9 MB   NSX_T_MANAGER-4.1.0.2.0-21761691
bundle-80029   5.0.0.0  2044.7 MB    SDDC_MANAGER_VCF-5.0.0.0-21822418
bundle-80030   5.0.0.0  251.3 MB     SDDC_MANAGER_VCF-5.0.0.0-21822418
bundle-80033   5.0.0.0  9867.6 MB    VCENTER-8.0.1.00100-21815093

In my case i need the installer. To download a specific bundle we run

./lcm-bundle-transfer-util --download --outputDirectory ${absolute-path-output-dir} --depotUser ${depotUser} -b ${bundle_name}

in my case it was:

./lcm-bundle-transfer-util --download --outputDirectory /some/temporary/location --depotUser [email protected] -b bundle-80029

This allowed me to grab the download from /some/temporary/path and save it/upload it on my other SDDC Managers that were missing it.

Finally before the patch can be used in SDDC Manager we need to upload it to the repo. Please note that once we issue the upload command the download gets deleted, so make sure you save the download ahead of time

./lcm-bundle-transfer-util --upload --bundleDirectory /some/temporary/path -b bundle-80029

Once the upload was complete i was able to see it in SDDC Manager as an package that i can apply.

Install/Upgrade ESXi 8.0 on unsupported hardware.

Apr 26, 2023
/
vSphere

As i was installing\upgrading my lab environment to ESXi 7.0 i received an error that the CPU was unsupported. As per the release notes vSphere 8.0 release notes my CPU is no longer on the compatibility list.

Since this is a lab environment i wanted to continue using my current hardware. It goes without saying that this method should not be used in a production environment.

To allow the legacy CPU all I had to do is boot up from the ISO, on the boot Menu I pressed TAB or Shift + O and added allowLegacyCPU=True option as seen in the screenshot below

NSX

I recently ran in to a problem where i couldnt delete an NSX segment so i went exploring the API. The API guide can be found here

The method used is delete policy/api/v1/infra/segments/{segment-id}?force=true

It would look like this in Postman:

To list the segments we can use a get request towards /policy/api/v1/infra/segments/

Removing NSX stale packages from ESXi host

Mar 03, 2023
/
NSX, VMware, vSphere

I recently ran in to a problem where i wanted to perform a clean configuration of one of my ESXi hosts from an NSX perspective, however i ran in to a problem where NSX was reporting that the packages are already installed. To fix the issue i had to run the following to list the packages installed:

esxcli software vib list | grep -i nsx

Once i had the list all i had to do is uninstall them using:

esxcli software vib remove -n packagename1 -n packagename2 ...

Once the uninstall was complete i was able to redeploy NSX from the NSX Manager

Configure NSX-T to use vIDM as authentication

Mar 03, 2023
/
NSX, VMware

I needed to create a few additional accounts in NSX-T for outside sources. Instead of creating individual accounts i wanted to use the existing ones from AD.

To get started we need to get the certificate from the vIDM server. Log on to the vIDM server as root and run the following:

openssl1 s_client -connect <FQDN of vIDM host>:443 < /dev/null 2> /dev/null | openssl x509 -sha256 -fingerprint -noout -in /dev/stdin

Next we need to create the OAuth client ID in vIDM. Log in to the vIDM UI using the url <FQDN of vIDM host>SAAS/admin/app/page#!/dashboard as admin and Navigate to Catalog -> Settings

Navigate to Remote App Access -> Clients -> Create Client

In the Access Type chose Service Client Token, Client ID can be anything. Under Advanced click on Generate Shared Secret (take a note of this because we need it on the NSX side)
