Upgrade to vSphere vSphere 4.1 5 - V

Written by jl on March 21st, 2013

Hello everyone

Next step in the process of upgrading to vSphere 4.1 5 and in this case we will try to update the ESX servers. In the environment we 3 4.1 ESX servers and in this case the update not only the updated version 5 but we will have ESX to ESXi version is the only supported from the 5 version.

For this process we will use the update manager, but comment if someone is in the case, if the ESX servers are migrated from previous to 4 versions, the upgrade can not be done with the update manager and do it from the installation cd. We have made this process as a test old server and the update is done without any problem.

Updating ESX hosts

In the next image we can see the vCenter version of ESX that we will update it 4.1 2 update


In the vCenter let's Home and part of Solutions and Applications click on Update Manager


In the next screen select ESXi Images tab, and click on the right part of the link Esxi Image Import (also on the right panel we get that option) to import the esxi iso image that we had previously to download from the VMware site.


Opens the next screen and give the browse button to select the image you want to upload the update manager, which in our case is the update version 5 2




Once selected next and give to us the following message security with certificates


Image starts up



Once we create a new Baseline rise, we name and give it to finish


At this point you have the iso image uploaded in the update manager as we can see in the picture below


The next step we do is migrate the host machines that we will update the other two hosts of the cluster. Although this step that we could not do it manually because in the upgrade process automatically does prefer to be the first to do so in a controlled hosts.

Once the machines migrated to update select the host in the vCenter tree, we go to the Update Manager tab and click on the link Attach.

We see the following screen with the baselines that have created and select the Upgrade ESXi (which is the one we created in the previous step and we call it that) and press attach


Back on the main screen we give the Update Manager Remediate button to begin the update


Upgrade Baselines selected and in this case having only one the mark


We accept the license


The next screen tells us that on failure no turning back and gives us the ability to remove third-party software


In the next step we can schedule the update task, in our case we select immediately


Before you begin the upgrade, the hosts will be in maintenance mode and on this screen you select different options. In our case though is not going to implement anything because we migrated above the machines marked the defaults.


The next option we can choose to disable features during the upgrade, that once re-enabled automatically.

In our case we disable Fault Tolerance, FT, Distributed Power Management, DPM, and High Ability, HA


Next we give the update starts and take a few minutes, and in our case there has been no problem


Once the update redistribute the machines I did the same process for the other two teams.

As seen in the picture above the team updated this with a temporary license 60 days, so I would have to get the new license we generated in the first step. In a previous blog article, Xavi explained the process, so I leave here the link

In the next article we will discuss the next step is to update the vmtools and hardware virtual machines.
