Retrieving CPU Microcode revision from ESXi in vSphere 8.0 Update 3

by // Leave a Comment

Whether you are applying a CPU microcode update through a hardware vendor's BIOS update or an ESXi update/upgrade, verifying the CPU microcode revision within ESXi is not as easy as it could be.

Today, if you wanted to get the current CPU microcode revision from ESXi, you would need to enable SSH and then use the vsish interface to retrieve this information by running the following command:

vsish -e cat /hardware/cpu/cpuList/0 | grep "microcode" -A2

While you can retrieve the CPU microcode revision, the method and required interfaces was less than ideal, especially at scale. Given ESXi already exposes a number CPU attributes via the ESXCLI interface, which includes programmatic access when using PowerCLI, I thought it would be a nice feature to also include the CPU microcode revision as part of the output and had filed an internal feature enhancement a few years back.

Downgrading new VMware vSphere Foundation (VVF) or VMware Cloud Foundation (VCF) licenses to 7.x

by // 5 Comments

When you access your new VMware vSphere Foundation (VVF) or VMware Cloud Foundation (VCF) license in the Broadcom Support Portal (BSP), it is delivered using the new solution license key type  which can activate multiple components within a VVF or VCF deployment.

By default, VVF and VCF licenses will come entitled for latest vSphere 8.0 Update 2b and VCF 5.1.1 respectively, because those are the minimum versions that support the new solution license key type. With that said, users can also downgrade their existing VVF and VCF licenses to support earlier vSphere 8.x and 7.x releases using the BSP license management system, which was something I had recently learned about and went through the process myself, so here is what it looks like end-to-end.

Note: License downgrade requires both user downgrade permissions in the BSP license management as well as using non-NFR licenses, which can obtained through the BSP self-service "Trials and Beta" or internally for employees. For NFR licenses, downgrade is not available.
