VMware ESXI Custom Image Upgrade

I'll base my notes off of Dell PowerEdge R740 servers.

There are a few different approaches to custom image upgrades, this is just how I've done it.

Pre-Upgrade Checks

  1. Log into vCenter and go to a host to obtain the model (Poweredge 740, for example)
  2. Go to Dell's website and search for firmware release updates - if there is a version later than what you're running, upgrade this, first
  3. Determine what version of ESXI will be needed.
    • From vCenter: Select the host > Configure tab > System > Licensing > the Product column is what you need, ie: VMware vSphere 6 Essentials Plus (CPUs)
  4. Check hardware compatibility for the planned version
  5. Confirm the upgrade path compatibility

Obtain the Upgrade Package

The image can also be obtained from Dell's site, but I find Dell's image is more out of date than VMware's.

  1. Log into my.vmware.com
  2. (At the top panel) Products > My Products > All Products tab > VMware vSphere (not other vSphere listings! The one written exactly as shown)
  3. At the left of the same column: View & Download products
  4. At the top of the page, select the ESXI version you're upgrading to (defaults to to current latest, 7.0)

  5. Custom ISOs tab > expand OEM Customized Installer CDs > select your harware's latest version, ie. DellEMC Custom Image for ESXi 6.7U3 GA

    For existing installs: DellEMC Custom Image for ESXi 6.7 Offline Bundle; for a bare-metal install: DellEMC Custom Image for ESXi 6.7 Install CD

  6. At the left of the same column: Go to Downloads

  7. In vCenter, upload the downloaded .zip to a datastore

VMware Upgrade (using the .zip and not the vendor repo)

  1. Enable SSH (from vCenter) > Select the host you'll be updating > Configure > System > Services > SSH > Start

  2. Open a terminal and SSH into the host: ssh root@host_ip_address

  3. Backup the Host Config

    • vim-cmd hostsvc/firmware/backup_config - this will save a tar gzipped bundle to /scratch/downloads/ for a short period of time

    • The CLI command will return the following:

      Bundle can be downloaded at : http://*/downloads/5d4fc6f-1e4b-7470e-c45-ae6278684d11/configBundle-vmware.tgz

    • Replace the asterisk for your host's IP & run a wget, with the --no-check-certificate flag (if you're using a self-signed SSL, you'll get errors, otherwise):

      cd ~/Downloads && wget https://192.168.1.2/downloads/5206ac6f-1e4b-740e-c005-ae6265454d11/configBundle-vmware.tgz --no-check-certificate

  4. Make note of the version running

    vmware -vl

    VMware ESXi 6.5.0 build-14320405

    VMware ESXi 6.5.0 Update 3

  5. Put the host in maintenance mode: vim-cmd /hostsvc/maintenance_mode_enter (can also be done via the GUI by right-clicking the host > Enter Maintenance Mode)

  6. Go into the directory where the datastores live: cd /vmfs/volumes && ls -l

  7. cd into the datastore you put the zip into & ls -l to see the .zip you uploaded earlier

  8. List profiles contained in the zip package (note that the full pwd path is needed in the -d argument):

    esxcli software sources profile list -d /vmfs/volumes/bdcfsdsdsd/VMware-VMvisor-Installer-6.7.0.update03-16316930.x86_64-DellEMC_Customized-A06.zip
    • Output (make note of the Name value): text Name Vendor Acceptance Level ------------------------------- ------ ---------------- DellEMC-ESXi-6.7U3-16316930-A06 Dell PartnerSupported

  9. Perform the update based on the echo'd profile (this will begin the update):

    esxcli software profile update -d /vmfs/volumes/bdcfsdsdsd/Utilities/VMware-VMvisor-Installer-6.7.0.update03-16316930.x86_64-DellEMC_Customized-A06.zip -p DellEMC-ESXi-6.7U3-16316930-A06

    -p is the argument value returned from step 6.

  10. Once complete, the terminal will echo all of the packages updated and the following phrase:

    Update Result

    Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.

    Reboot Required: true

  11. Reboot the hypervisor and the update will be complete. reboot command via CLI, or do so from the GUI by right-clicking the host > Power > Reboot

  12. After reboot, check the running version

    vmware -vl

  13. Head back into vCenter and make sure SSH is turned off, on the host
