Using vmware vcenter update manager

During Remediation the Pre-Check Remediation will also run if you did not manually choose it before. We have a few options below so let's explore them, starting with seeing which updates we are installing. If we expand out the Install Updates, we can see all updates that will be applied to this object. The next section will cover whether or not you wish to remediate the object immediately or schedule for a future date or time.

If you choose to modify the scheduling options you can create a scheduled task to remediate the object at a later date or time. If you uncheck the option it will run immediately. Let's review the remediation settings. Within this screen we can see the remediation options that have been chosen, these are configured at the vCenter Server level, so if you wish to modify them you need to Close Dialog and Go to Settings.

Please note new features introduced with 6. Consult the Release Notes and Documentation for more information on these features. During an Update Manager remediation, if a host is not already in maintenance mode the first step is to put that host into maintenance mode, moving all running virtual machines to another host within the cluster.

Once the host is put into maintenance mode, Update Manager will automatically Install the updates and reboot the host. When remediation is complete, a Check Compliance scan is automatically ran and the host will be removed from maintenance mode.

Our remediation is now complete as our host is in Compliance with all the attached baselines. For more information and walkthroughs please view our VMware Blogs. This eliminates the time-consuming device initialization and self-testing procedures, shortening the time required to patch or upgrade a host. Downloading virtual appliance upgrades, host patches, extensions, and related metadata is a predefined automatic process that you can modify.

By default, at regular configurable intervals, Update Manager contacts VMware or third-party sources to gather the latest information metadata about available upgrades, patches, or extensions. Downloading information about all updates is a relatively low-cost operation in terms of disk space and network bandwidth.

The availability of regularly updated metadata lets you add scanning tasks for hosts or appliances at any time. Update Manager supports the recall of patches for hosts that are running ESXi 5. A patch is recalled if the released patch has problems or potential issues. After you scan the hosts in your environment, Update Manager alerts you if the recalled patch has been installed on a certain host. Recalled patches cannot be installed on hosts with Update Manager.

Update Manager also deletes all the recalled patches from the Update Manager patch repository. After a patch fixing the problem is released, Update Manager downloads the new patch to its patch repository. If you have already installed the problematic patch, Update Manager notifies you that a fix was released and prompts you to apply the new patch. If Update Manager cannot download upgrades, patches, or extensions — for example, if it is deployed on an internal network segment that does not have Internet access — you must use UMDS to download and store the data on the machine on which UMDS is installed.

You can configure Update Manager to use an Internet proxy to download upgrades, patches, extensions, and related metadata. You can change the time intervals at which Update Manager downloads updates or checks for notifications.

You can import offline bundles and host upgrade images from a local storage device into the local Update Manager repository.

This message will close in seconds. You are about to be redirected to the central VMware login page. After specifying a baseline name, verifying the ESXi image, and reviewing the details, click "Finish" Confirm Upgrade Baseline After creating the upgrade baseline, verify that it is listed on the Baselines tab. To begin the cluster upgrade procedure, click "Hosts and Clusters" Attach Baseline VUM is most effective when a baseline is attached to a cluster of ESXi hosts, although it is possible to attach to individual hosts, if necessary.

With the cluster selected, click "Attach" Select Baseline to Attach In the dialog box, we can choose one or more baselines to attach to this cluster. Click OK Check Cluster Compliance 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" Verify Compliance and Check Remediation Status Once Update Manager is finished checking each host in the cluster, the results are displayed in the center information card.

Streamlined Remediation In the new Update Manager interface, the remediation wizard from previous releases is gone. Click OK Upgrade Without Downtime During the cluster remediation process, hosts are put into maintenance mode after the running VMs are migrated to other cluster nodes. Verify Cluster Upgrade When Update Manager is finished upgrading the cluster, the status information cards will show that the cluster is now compliant.

Using the Update Manager 6. View the Updates Repository Once the ESXi patch has finished importing, the individual bulletins can be seen in the repository tab. Review Baselines Update Manager is able to perform major version upgrades, apply patches, or install extensions on managed ESXi hosts. New Baseline On the Baselines tab, the "New" menu item has two sub-entries, choose "New Baseline" Baseline Definition Wizard To create a new baseline, we need to supply a name and an optional description.

Manual Patch Baseline 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. Select Patches For this baseline, we will select the two patch bulletins that are part of the bundle we just uploaded. Verify Baseline One final check of the patch baseline Everything looks good, so click Finish.

Confirm Patch Baseline After creating the new baseline, it appears in the list. Click Hosts and Clusters Prepare to Patch the Cluster With the target cluster selected, click Attach to select the patch baseline we just created. Select Patch Baseline We can attach the new patch baseline by checking the corresponding box.

Click OK Check Baseline Compliance 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 Cluster Not Compliant Once the compliance check is finished, Update Manager will indicate the status of each host in the cluster. Before we begin, we will first check the cluster for any potential blocking issues by using the pre-check. Click Pre-Check Remediation.

With Update-Entity I can automatically begin the process of patching or upgrading all the hosts in a cluster with the option of performing remediation in parallel. While performing remediation in parallel, vCenter will automatically calculate how many hosts it can remediate concurrently and load balance VMs using Distributed Resource Scheduler DRS on the hosts it is not remediating. The process of patching a cluster is almost identical to performing a patch on an ESXi host.

The main difference is that I am specifying the cluster in the -Entity parameter as well as some additional parameters in the Update-Entity command. Now I can run Update-Entity specifying to disable distributed power management, high availability, and fault tolerance, which VMware recommends. Subscribe to 4sysops newsletter!

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. Enter a name and description for a new baseline. In the current example, the name is ESXiupgrade. Hit Next to continue. Select an ESXi release image. The ESXi 6. Hit Next. The baseline has now been created, and you can see the created baseline in the Baselines tab of VMware Update Manager. Select your custom upgrade baseline ESXiupgrade in this case and click Attach. The compliance check allows you to verify the state of updates added to baselines and notify whether or not there are conflicts.

If update or upgrade is unsupported, VMware Update Manager will notify you when performing the check compliance. In our example, the host compliance status is non-compliant , but upgrade can be technically done for selected hosts. Pre-check remediation should be performed to verify conditions and identify possible problems that may occur after remediating.

If there are possible issues, the list of recommended actions is displayed. Wait for a while until the checking process is finished. If there are warnings after finishing the pre-check remediation process, perform the recommended actions to fix the issues. If everything is correct and no actions must be performed to begin remediation, go to Hosts and Clusters , select your ESXi host, select the Updates tab, and open the Host Updates category in the Overview section.

Select the required baseline ESXiupgrade in this case and click Remediate. Select the ESXi hosts that need to be remediated, edit settings if needed scheduling settings, remediation options , and click Remediate.
