Upgrading ESXi 4 to Update 1 – Host Update Utility

Now that we’ve upgraded our client and installed it on Windows 7, let’s upgrade our ESX or ESXi host:

1. Fire up Host Update Utility & Download new Patches from VMware:

    What if it fails connecting to the patches repository with the message "An error has occurred. Download failed."?? Thank you.
  • Does it consistently fail at this step? Have you verified external
    connectivity, etc?

    sat at 45% for a long time but eventually completed.
  • Good stuff! So about how long did it take?
  • Henrik Svendsen
    Took mine about 30 - 45 min...
    Fujitsu Siemens Primergy TX120@1800Mhz + 5 GB ram.

    How long did this update take? I've been sat @ 45% for a while now.

    Thanks. After you showed how easy this was, I upgraded my ESXi build... but after it reboots, the header shows 4.0.0,219382 - I thought it would show 4.0.1.

    there is no "4.0.1". this is 4.0 update 1. it's the vmware equivalent of a service pack, thus only the build number changes.
