VCF On VxRail – 3.9.0 -> 3.9.1 Upgrade (Part2: VI WLD)

Part 1: Walk-thru upgrade of a VCF MGMT Workload Domain

In this post I will provide an example walk-thru upgrade of a VCF VI Workload Domain:

VCF 3.9.0 (VxRail 4.7.300) -> 3.9.1 upgrade (VxRail 4.7.410)

One of the great advantages of a VCF On VxRail solution is the ability to LCM your entire SDDC stack in an automated fashion driven through a single user interface (SDDC Manager). The following post details how you step through this LCM process for a VI WLD.

By expanding the Current Versions tab within SDDC manager it is possible to view the full list of components deployed as part of VCF and their respective current running code versions. The following is a very useful VMware kb article detailing the BOM for each VCF release:

Correlating VMware Cloud Foundation version with the versions of its constituent products

It is also advisable to read the release notes of the target versions prior to performing the upgrade:

VMware Cloud Foundation 3.9.1 on Dell EMC VxRail Release Notes

This upgrade consists of a 3x BUNDLE upgrade process executed in the following sequence:

  1. VMware Software Upgrades NSX-V from 6.4.5 to 6.4.6 (6.4.6-14819921 2GB)
  2. VMware Software Upgrades PSC/VC from 6.7 U3 to 6.7 P01 (6.7.0-15132721  2GB)
  3. VXRAIL UPGRADE BUNDLE VERSION 4.7.410-26262335  4 GB

The sequence of the upgrade is defined within SDDC Manager itself. SDDC Manager presents the next available upgrade bundle throughout the procedure which makes the overall procedure quite easy and seamless to the end user performing the upgrade. In an effort to incrementally speed up the process of upgrading it is advisable to download all the required bundles in advance (bundles marked as available/future apply). After each of the bundles have been downloaded click View Details, which details the version changes that will be applied as part of the bundle upgrade. The update bundles can be applied manually or scheduled for a preferred time window.

Ensure to run the upgrade Precheck task from within SDDC Manager in order to validate VCF is in a healthy state before proceeding with each of the upgrades and view the health status of each component by expanding their respective results. If the precheck has failed, fix the issue and then retry the precheck task to repeat the validation process.

Before proceeding with the upgrade ensure to take snapshots of your management virtual machines. Do not perform any SDDC workflows such as VI WLD creation or WLD expansions during the upgrade and confirm no failed workflows or errors are displayed in SDDC manager.

While proceeding with the updates, click on View update activity to monitor progress and track progress via the lcm log:

tail -f /var/log/vmware/vcf/lcm/lcm.log

It is also possible to confirm a successful update via the SDDC manager ssh console:

cat /var/log/vmware/vcf/lcm/lcm.log | grep “reached final state COMPLETED_WITH_SUCCESS”

All of the above steps/guidelines are displayed as part of the walk-thru series detailed for each of the 3 upgrades below.
