PowerCLI Script to get ESXi Network/Storage Firmware and Driver Version

For a healthy vSphere virtualization infrastructure and to receive support from VMware it is important to verify that IO devices are listed in VMwares Compatibility Guide/Hardware Compatibility List (HCL) with their correct driver and firmware version. Gathering firmware details and comparing them to the HCL is very time-consuming. I made a small script that automatically gathers the following information:

  • IO Devices (NICs, HBAs and RAID Controllers)
  • Driver Version
  • Firmware Version
  • Official HCL Link

VMware Homeserver - ESXi on 7th Gen Intel NUC (Kaby Lake)

Intel's 7th Gen NUC is currently rolled out and after a resolved issue with the NIC driver, it's time to take a look at their capabilities as homeserver running VMware ESXi. NUCs are not officially supported by VMware but they are very widespread in many homlabs or test environments. They are small, silent, transportable and have a very low power consumption, making it a great server for your homelab. I've posted a preview of the new models about 2 months ago. Gen7 NUCs are available with i3, i5 and i7 CPU.

vmware-hcl-65Beside Server Hardware, also double check if your IO Devices (eg. NIC, HBA,..) are supported when updating ESXi hosts from VMware vSphere 6.0 to 6.5. The following devices were supported in vSphere 6.0 but are according to VMwares HCL not (yet) supported in vSphere 6.5.

  • Not supported does not say that it does not work.
  • The list has been created with the help of my IO-Devices HCL in JSON Format.

Script to add vSphere 6.5 VMCA Root Certificate to Trusted Certs Store

When running vSphere 6.5 deployments in default (recommended) mode, VMware Certificate Authority is its own root certificate authority. Everything fine and secure with this configuration, but your browser displays a warning because the root certificate is not trusted.

I made a little script (VBS) that pulls the CA certificate from a vCenter Server or Platform Services Controller and adds it to the local trusted root certificates store. When the root CA is trusted, browser warnings are gone.

Heads Up - ESXi not working on 7th Gen (Kaby Lake) Intel NUC7

I've received reports that the ESXi 6.5 and ESXi 6.0 installer fails to load on the latest 7th Gen NUCs:

  • NUC7i3BNH
  • NUC7i3BNK
  • NUC7i5BNH
  • NUC7i5BNK

The main issue is that the I219-V NIC is not recognized, so the installer fails with the well known "No Network Adapters" error message. Today I managed to get my hands on a NUC7i3BNH to narrow down the issue. By now I've not managed to get the embedded Network Adapter to work. A workaround with a USB-based NIC is possible.

[Update 2017-02-25 - A fix is available]
