Updating ESXi 6.0 to Update 2

Hi all, this is a very quick  post (mostly for my memory!) on how to update ESXi 6.0 to the latest version easily.

New features in Update 2 are:

  • High Ethernet Link Speed: ESXi 6.0 Update 2 supports 25 G and 50 G ethernet link speeds.
  • VMware Host Client: The VMware Host Client is an HTML5 client that is used to connect to and manage single ESXi hosts. It can be used to perform administrative tasks to manage host resources, such as virtual machines, networking, and storage. The VMware Host Client can also be helpful to troubleshoot individual virtual machines or hosts when vCenter Server and the vSphere Web Client are unavailable. For more information about VMware Host Client, see VMware Host Client 1.0 Release Notes.
  • VMware Virtual SAN 6.2: The new VMware Virtual SAN 6.2 is bundled with ESXi 6.0 Update 2. For more information about Virtual SAN, see VMware Virtual SAN 6.2 Release Notes.
    Virtual SAN adds a new vsan vib in the ESXi image. The new vib results in a dependency being added to the esx-base vib requiring the vsan vib to be installed on the new 6.0 Update 2 host. For more information, see Knowledge Base article 2144595.
  • vSphere APIs for I/O Filtering (VAIO) Enhancement:
    • ESXi 6.0 Update 2 supports the IO Filter VASA Provider in a pure IPv6 environment. For additional information, see the Resolved Issues section.
    • ESXi 6.0 Update 2 supports the VMIOF versions 1.0 and 1.1. For additional information, see the Resolved Issues section.

    I used to do this via vCenter update manager but this method seems easier as you can do it on the host directly so less chance of things going wrong. So lets get to it.

    The first step is to ensure that all VMs are either shut down or migrated off the host. Once that is done place the host into Maintenance Mode.

    Now we need to enable SSH if this is not already enabled. Ensure the Daemon is running

    Now we can connect to he host and begin the update

    Copy and paste the following commands:

    esxcli network firewall ruleset set -e true -r httpClient

    esxcli software profile update -p ESXi-6.0.0-20160302001-standard -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

    After a few minutes the update process should be complete.

    Easy! Now take your hosts out of maintenance mode and enjoy the new features and bug fixes Smile
