Upgrading ESXi itself is now possible with the new Embedded Host Client v4

12.21.2015 by William Lam // 13 Comments

It looks like we just got an early Christmas gift from Etienne, George and the VMware Flings team with the release of v4 of the ESXi Embedded Host Client (EHC). One of the new features that I am most excited about is the ability to upgrade ESXi itself using the "Update" feature which was first introduced in EHC v3. In the previous release of EHC, you could install or patch any ESXi VIB using this interface which I had blogged about here. With the latest release, Etienne has expanded its functionality to not only allow for a VIB URL but also a metadata.zip URL which ESXi offline bundles contain.

Here is an example of using EHC v4 to upgrade an ESXi 6.0 host to ESXi 6.0 Update 1:

Step 1 - Download ESXi offline bundle of choice, in this example we are downloading the offline bundle for ESXi 6.0 Update 1:

Step 2 - You will need to extract the contents of the offline bundle and then upload the content to either a vSphere Datastore or an HTTP accessible URL as shown in the screenshots below.

Currently it is not possible to upload an entire directory using the Datastore Browser with EHC. This is something I have reported internally and hopefully will be fixed in a future update.

Step 3 - Click on the "Help" menu on the upper right hand corner of the Embedded Host Client and select the "Update" option which should prompt you to specify a URL. You can either specify a local datastore path to the metadata.zip such as the following:

/vmfs/volumes/datastore1/ESXi600-201510001/metadata.zip

or you can specify an HTTP(s) URL to the metadata.zip like the following:

http://192.168.1.180/ESXi600-201510001/metadata.zip

Step 4 - Once you click the "Update" button, you will be asked to confirm and then you should see task kicked off called "Install Host Patch V2". Once the task has completed, you will need to reboot the ESXi host for the changes to take effect. If you are interested in viewing the update logs without having to log in via SSH, you can click on the "Monitor" tab of the Host option and under "Logs", click on /var/log/esxupdate.log to see the progress.

If you have more than one or two hosts, I definitely recommend uploading the extracted offline bundle onto a webserver or a shared vSphere Datastore which you can the access from multiple ESXi hosts. This is a very nice way to easily upgrade your ESXi hosts without having to go into the ESXi Shell or enable SSH. Pretty neat feature if you ask me! There are many other new enhancements included in this release, be sure to give them a try and let us know if you have any feedback by leaving a comment on my blog or better yet, directly on the Fling site.

How to upgrade from VCSA 5.x & 6.x to VCSA 6.0 Update 1?

09.11.2015 by William Lam // 100 Comments

I have seen quite a few questions come in on how to properly upgrade from an existing vCenter Server Appliance (VCSA) 5.x and/or 6.x environment to the latest vSphere 6.0 Update 1 which was just released today. Before I jump straight into the process, I think its worth covering on how updates (patches) and upgrades have traditionally been handled for the VCSA. In an update or patch scenario, you are staying within a major release of vSphere (e.g. vSphere 5.0) and moving to something like vSphere 5.0 p01 and in this case, an in-place update or patch is performed. In an upgrade scenario, where you are moving from one major release (e.g. vSphere 5.0) to another major release (e.g. vSphere 6.0), a "migration based" approach is taken. This means that you would need to deploy the new VCSA that you wish to upgrade to and then migrate the data from your old VCSA appliance to the new one which is part of the upgrade workflow. This "migration based" approach was also true for any "U" (Update) releases (e.g. vSphere 5.5 to vSphere 5.5 Update 1).

For major releases, this makes perfect sense and provides customers a nice way to easily rollback if something goes wrong. You simply power off the new VCSA and then power on your original VCSA and you are back in business. For update releases, we have heard from our customers that this process was not ideal and though there is always a risk when updating software (which is why I always recommend customers test thoroughly in a Dev/Test environment before moving to production), the amount of changes in the code is significantly less when compared to a major upgrade. One of the new features that we have introduced in vSphere 6.0 Update 1 is an in-place upgrade for "U" (Update) releases which I have already blogged about here among other new features.

This means that if you are coming from a VCSA 6.x environment and you wish to upgrade to vSphere 6.0 Update 1, you simply just mount the vSphere 6.0 Update 1 Patch ISO to your VCSA 6.x environment and perform the update from the command-line via the appliancesh interface. This is quite nice as it reduces the need to copy data between your old and new appliance and helps reduce the overall downtime. In fact, you can upgrade to vSphere 6.0 Update 1 in about 10min or so using this new method. If you are coming from a VCSA 5.x (5.0, 5.1 or 5.5) environment, this would be consider a major to major upgrade and you would need to follow the "migration based" approach to upgrade to vSphere 6.0 Update 1. One other thing to note after you have upgraded to vSphere 6.0 Update 1, we have now re-introduced URL based patching via the VAMI interface. This means in the future, you no longer need to update or patch from an ISO but can do so directly from VMware's online repository.

Below are the instructions on upgrading from VCSA 6.x to VCSA 6.0 Update 1:

Note (09/14/15):

If you have an External PSC with your VCSA 6.x and wish to upgrade, the process shown below is the same for both the PSC and the VCSA. You will want to first upgrade your PSC first as that provides authentication to your vCenter Server. Once the PSC has been upgraded and accessible on the network again, you will then want to move to your VCSA. If you are interested in the proper sequence and ordering of VMware Products to update, you can also check out this handy VMware KB 2109760 which provides all the details
Thanks to fellow reader Idan for reporting this but it looks like after an upgrade of the VCSA, the default VMware URL for the VAMI is not working. You will need to update it to point to the following URL https://vapp-updates.vmware.com/vai-catalog/valm/vmw/647ee3fc-e6c6-4b06-9dc2-f295d12d135c/6.0.0.10000.latest/ instead of the default one as shown in the screenshot below. This is only applicable for upgrade scenarios. If you deploy a new VCSA 6.0 Update 1, it will automatically be using the correct URL

Step 0 - Ensure you have a proper backup and take a snapshot of your VCSA 6.x appliance before beginning.

Step 1 - Download the VCSA 6.0 Update 1 Full Patch (VMware-vCenter-Server-Appliance-6.0.0.10000-3018521-patch-FP.iso) by visiting the VMware Patch Download site.

Step 2 - Mount the VCSA 6.0 Update 1 Patch ISO to your VCSA 6.x appliance using either the vSphere Web/C# Client

Step 3 - Login to your VCSA 6.x appliance via SSH to the appliancesh interface. If you have disabled that, simply type "appliancesh" and login with the root credentials.

Step 4 - Run the following command to stage and install the patches from the VCSA 6.0 Update 1 Patch ISO:

software-packages install --iso --acceptEulas

Note: If you run into any errors while either staging or installing the patches, you should drop into the bash shell and take a look at /var/log/vmware/applmgmt/software-packages.log file for additional information. One common issue that I have seen in the past is if your /storage/log partition is full and you may need to perform a clean up before continuing.

Step 5 - Once the upgrade has completed, you just need to reboot your VCSA by running the following command:

shutdown reboot -r "Updated to vSphere 6.0u1"

Step 6 - A quick way to confirm that you have successfully upgraded your VCSA to vSphere 6.0 Update 1, simply open a browser to the following URL: https://[VCSA-IP]:5480 and it should take you to the new HTML5 VAMI interface.

If you would like additional information, take a look at this VMware KB 2119924.

A Pretty Cool Method of Upgrading to ESXi 5.1

09.18.2012 by William Lam // 41 Comments

I recently came across an interesting article by Andreas Peetz which shows you how to patch an ESXi host using an image profile that is directly available on VMware's online depot within the ESXi shell. I knew that VMware had online depots for use with VUM and Auto Deploy but I was not aware of this particular method, especially directly from the host.

Disclaimer: This method assumes you can install the default ESXi Image Profile with no additional drivers or packages, else you may have connectivity issue after the upgrade. If you still need to customize the ESXi Image Profile before installation, you will still need to use something like Image Builder and then upload that to your online depot.

Note: There are many ways that you can patch/upgrade your ESXi hosts, here is another article that provides more details for command-line only methods.

Before you get started, you will need to make sure that your ESXi host has the httpClient firewall rule enabled, else you will not be able to connect to VMware's online depot. To enable this, run the following ESXCLI command:

esxcli network firewall ruleset set -e true -r httpClient

Also make sure that your ESXi host can reach the following URL (you can specify a proxy if needed):

https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

To view the available ESXi Image Profiles, run the following ESXCLI command (use the --proxy if you need to specify a proxy to reach VMware's online depot):

esxcli software sources profile list -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

If you are able to successfully connect to the online depot, you see a list of all the ESXi Image Profiles that are available to you. You will see two ESXi 5.1 Image Profiles (these were recently published), one with VMware Tools and one without VMware Tools.

Note: Before you begin, make sure you do not have any running VMs and put your host into maintenance mode.

Let's go ahead and upgrade our ESXi 5.0 Update 1 host to latest ESXi 5.1. To install the new Image Profile, run the following command:

esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-5.1.0-799733-standard

This can take a few minutes to complete depending on how fast you can pull down the Image Profile. Once it is done, you will see all the new VIBs that have been updated and you will be asked to reboot for the changes to go into effect and then you will be running ESXi 5.1! Pretty cool IMO!
