Upgrade from ESXi 6.7 to ESXi 6.7 U2 using VMware Update Manager

What:

Upgrade from ESXi 6.7 to ESXi 6.7 U2 using VMware Update Manager. Every vSphere release comes with a number of patches, fixes and new features that are important to keep the harmony of your infrastructure.

This method is the one you need to use for ESXi clusters and productions environments. VMware will automatically put your ESXi in maintenance mode, migrate your VMs to available hosts, then upgrade and reboot the hosts (host by host).

You can also upgrade the ESXi via CLI, and you have two options:

What's New

  • Solarflare native driver: ESXi 6.7 Update 2 adds Solarflare native driver (sfvmk) support for Solarflare 10G and 40G network adaptor devices, such as SFN8542 and SFN8522.
  • Virtual Hardware Version 15: ESXi 6.7 Update 2 introduces Virtual Hardware Version 15 which adds support for creating virtual machines with up to 256 virtual CPUs. For more information, see VMware knowledge base articles 1003746 and 2007240.
  • Standalone ESXCLI command package: ESXi 6.7 Update 2 provides a new Standalone ESXCLI package for Linux, separate from the vSphere Command Line Interface (vSphere CLI) installation package. The ESXCLI, which is a part of the vSphere CLI, is not updated for ESXi 6.7 Update 2. Although the vSphere CLI installation package is deprecated for this release and is still available for download, you must not install it together with the new Standalone ESXCLI for Linux package. For information about downloading and installing the Standalone ESXCLI package, see VMware {code}.
  • In ESXi 6.7 Update 2, the Side-Channel-Aware Scheduler is updated to enhance the compute performance for ESXi hosts that are mitigated for speculative execution hardware vulnerabilities. For more information, see VMware knowledge base article 55806.
  • ESXi 6.7 update 2 adds support for VMFS6 automatic unmap processing on storage arrays and devices that report to ESXi hosts an unmap granularity value greater than 1 MB. On arrays that report granularity of 1 MB and less, the unmap operation is supported if the granularity is a factor of 1 MB.
  • ESXi 6.7 update 2 adds VMFS6 to the list of supported file systems by the vSphere On-disk Metadata Analyzer (VOMA) to allow you to check and fix issues with VMFS volumes metadata, LVM metadata, and partition table inconsistencies.

I was switching my storage array, so I migrated the VMs from that old datastore/storage to a new datastore/storage. The old datastore was shared by 3 ESXi hosts, no cluster. After migrating the VMs and unmount/delete the datastore, it was still presented in two of the ESXi hosts and was marked as inaccessible.
