In this scenario, we want to choose just the ESXi 6. Click OK. With the desired baseline now attached to the cluster, we will have Update Manager check each host to see if they are currently compliant or if they will need to be remediated. Click "Check Compliance". Once Update Manager is finished checking each host in the cluster, the results are displayed in the center information card. Here we can see that all four of these hosts are not compliant with the baseline and will need to be remediated.
Before we do that, let's run the cluster pre-check to ensure that remediation will be successful. Click "Pre-Check Remediation". The pre-check process will check to see if DRS is enabled so that running VMs can be migrated with zero-downtime across the cluster.
The pre-check also displays the status of HA admission control and enhanced vMotion compatibility. Click "Done". After running the pre-check, verify that the cluster is ready for upgrade.
Click "Remediate" to begin. In the new Update Manager interface, the remediation wizard from previous releases is gone. Instead, we have a chance to review the actions that will be taken in a very efficient way. During the cluster remediation process, hosts are put into maintenance mode after the running VMs are migrated to other cluster nodes. This process is repeated, typically one host at a time, until the entire cluster is upgraded. Click the Refresh link to see the final status.
When Update Manager is finished upgrading the cluster, the status information cards will show that the cluster is now compliant. This concludes the new Update Manager interface demo. VMware vSphere Update Manager is capable of performing major version upgrades, applying patches and updates to supported versions of ESXi host, or installing drivers or other third-party components.
In this example, we will walk through the procedure to apply a patch to a cluster of hosts running VMware ESXi 6. For improved security, some environments do not allow Internet access from datacenter management components. In this demonstration, Update Manager does not have Internet access, so we will manually import the specific patches deemed necessary.
These patches, sometimes called offline bundles or depots, can be downloaded by logging into My VMware; they are distributed in zip format. Click Import to begin. Click Import to complete the process. Once the ESXi patch has finished importing, the individual bulletins can be seen in the repository tab.
Everything looks good, click the Baselines tab to continue. Update Manager is able to perform major version upgrades, apply patches, or install extensions on managed ESXi hosts.
Each of these tasks are enabled via baselines In our patching scenario, we need to create a new baseline to act as a container for the patches we just imported. Click New. To create a new baseline, we need to supply a name and an optional description. In this environment, there are tight controls for compliance reasons - we will specify the exact patches to install instead of dynamically matching patterns through the automatic feature - uncheck that option and click next.
For this baseline, we will select the two patch bulletins that are part of the bundle we just uploaded. Since this environment does not have Internet access, only the patches that we import to the repository appear in this list. In a lessrestrictive datacenter, this list would include all possible patch releases and could be filtered as needed by clicking the column headings. Click Next. Now that the baseline is attached to the cluster, Update Manager will check each host to see if action is required in order for that host to be considered compliant.
Click Check Compliance. Once the compliance check is finished, Update Manager will indicate the status of each host in the cluster. In this case, all of the hosts are out of compliance and need to have the patch installed, as expected.
Before we begin, we will first check the cluster for any potential blocking issues by using the. The pre-check dialog box will show the status of individual items, such as confirming DRS is enabled. Everything is ready for remediation, so click Done. Update Manager 6. After reviewing the actions that will be taken, click OK. Update Manager evacuates hosts one at a time and places them into maintenance mode before applying the patches. Running VMs are moved to other hosts with vMotion.
Click Refresh to check the cluster status. After Update Manager is finished applying patches to all nodes in the cluster, the status will be updated to show that they are compliant with our chosen patch baseline. VMware vSphere 6. By default, there are no baselines attached to a cluster. Since we are using precreated baselines we will proceed to attach those baselines to the host for remediation. As we already have existing baselines, we will choose the option to Attach Baseline or Baseline Group.
If we needed to create a custom baseline, we can choose the option to Create and Attach Baseline. Enter your Email address. Related Articles.

The advantages of using VMware Update Manager include flexibility and the possibility to install VMware patches on multiple hosts at once. 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.
