You can get a better understanding of them by simply taking a look at Update Manager, and the patches available in it:. There are patches and rollups available for ESXi. I prefer rollups, since they include all patches. You may elect to apply a specific patch if you are trying to solve a specific problem and have been instructed to do so by VMware support, or if the latest patch available does not include a rollup. If you are already familiar with VMware vSphere Update Manager, a new baseline for patches is just like creating any other baseline.
You may want to take a look at some of my other Update Manager guides like:. Upgrade ESXi to 6. As I have mentioned previously, I prefer to use rollup patches when appropriate. The next step is to give your baseline a name that makes sense to you.
My ESXi hosts have been neglected for some time, so I will be applying the most recent baseline patch. Next, you will be asked about Automatic and Manual patch selection. I am going to skip the Automatic step and select my patches manually. However, if you wish to use Automatic patch selection, there are a number of filters you can apply.
Now, you may be wondering what these patches mean. Go to the Updates tab and scroll down to the Attached Baselines section. As mentioned previously, this also propagates the attachment to the esxa. You can verify this by going to the Updates tab of each of the hosts individually.
For example, to see the attachment for esxa. You have seen how to attach a custom baseline to a vSphere object, but what about removing them? The process for detaching patch baselines is very similar to attaching them. For example, to detach the two predefined patch baselines, Host Security Patches and Critical Host Patches, from the vcsaa. From the Hosts and Clusters view, click on the vcsaa. Baseline groups are used to group multiple baselines into a single logical container.
While they are completely optional, they can be useful if you need to deploy multiple baselines at the same time. Click Next to skip the Upgrade Baseline page as this is not necessary for this example. Click Next to skip the Extension Baselines page as it is not necessary for this example.
Review the Summary page and click Finish to create the baseline group. To understand which hosts are missing patches from a baseline you can run the check compliance task.
This will scan each of the targeted hosts and provide a status regarding whether they are compliant or non-compliant, helping you determine which hosts require remediation. Scroll down in the Updates tab to see which attached baselines are non-compliant. Select the MyCustomBaseline baseline and click Remediate to launch the remediate dialog. Such an approach also allows you to manage VMware patches centrally by using vCenter with VMware vSphere Client and helps you save time spent on vSphere administration.
You can also automate the ESXi patch installation. VMware Update Manager is universal and allows you to install VMware patches and third-party patches such as Cisco distributed virtual switch, updated drivers for Hewlett-Packard servers, etc.
Also, be sure to check the compatibility of your hardware with ESXi patches before you install these patches. Remember that in the most cases virtual machines must be shut down or migrated from ESXi hosts before starting remediation when you seek to update or upgrade these hosts. ESXi hosts enter the maintenance mode automatically when remediating. When remediation is done, ESXi hosts exit the maintenance mode, and a host reboot may be required. If you have chosen to remediate multiple ESXi hosts, the process of remediating the second host begins once the process of remediating the first ESXi host is finished.
In the current example, vCenter 6. You can select a VM folder, cluster or the entire datacenter if necessary. Update refers to installing patches that fix bugs on the current version. The build number is increased, but the version remains the same after applying an update.
For example, updating ESXi 6. Select the required ESXi host and check the version and build number in the Summary tab. You can also open the Updates tab to check the ESXi version and build. As you can see on the screenshot, ESXi 6. You should have all required packages before you can upgrade ESXi. Notice, that you should download the ESXi 6. Click Browse and select the ESXi 6. Click Import to import the image to a repository. Once your ESXi 6. A baseline is like a preset that can be applied to multiple entities, such as ESXi hosts, at once.
Baselines are divided to host baselines, VM virtual machine baselines, VA virtual appliance baselines. VM baselines and VA baselines cannot be created manually, as they are predefined. You can also create baseline groups. In the current example, a baseline includes one ESXi image for upgrade. However, you can select multiple patches updates , upgrades or extensions to add to a baseline. Then you can use one baseline to install multiple patches on ESXi hosts simultaneously.
