Updating to ESXi 5.1 Update 1 with the Offline Bundle

Update 1 for ESXi 5.1 has been out for a few weeks now and the release notes for vSphere ESXi 5.1 Update 1 can be found here. I had a few minutes of downtime so I decided to go ahead and update the ESXi host running my home lab. Not for any specific reason other than I had some time and wanted to get to the latest version.

I downloaded the offline bundle from My VMware.

Using the Datastore Browser I uploaded the offline bundle to a datastore that is accessible by the host I am upgrading.

To list out the image profiles that are contained in the offline bundle using esxcli.

esxcli software sources profile list -d /vmfs/volumes/datastore1/update-from-esxi5.1-5.1_update01.zip


Now apply the image profile update ESXi-5.1.0-20130402001-standard from the offline bundle with esxcli.

esxcli software profile update -d /vmfs/volumes/datastore1/update-from-esxi5.1-5.1_update01.zip -p ESXi-5.1.0-20130402001-standard

Once the update completes a host reboot is required.

After I rebooted the host the build number changed to 1065491 which corresponds to ESXi 5.1 Update 1.

Now to update VMware Tools on all my lab VMs. Not a big deal though since the tools update does not require a reboot! Nice!

Here is a great post on performing the update by downloading the bundle from the VMware update repository directly to the host – http://vninja.net/vmware-2/quick-dirty-esxi-5-1u1-upgrade/ – great write up.

Good to know the update can be applied a number of different ways; using VUM if your host is managed by vCenter, using the offline bundle, or by connecting directly to update repository from the host.

    Did you upgrade vCenter first?

    • This is a standalone ESXi host that serves as the base for my home lab. It is not managed by vCenter. If it was then the vCenter Server would need to upgraded to U1a first before apply the host update.


  • Recently moved vMotion to our 10gb adapters, and let VUM apply this update to a cluster of 20 hosts/500ish vms two hosts at a time in just over 2 hours. Was very pleased!
