The ESX 4 downloads can be disabled by running:. This can be used to allow UMDS to connect to the websites of third party software vendors, to download their host patches.
Once you have your patches downloaded, the next step is looking at how to make them available to Update Manager. There are a couple of ways you can do this depending on your environment. If you wish to export all the downloaded patches to an external drive, for transfer to the Update Manager server, you can do so by running, for example:. After creating the virtual directory, the.

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. Once all baselines have been selected we will proceed to choose Attach to associate them with our ESXi host. The next thing we need to do is Check Compliance of our host against Update Manager. Check Compliance does a check of currently installed patches, updates and upgrades installed on the ESXi host against what is within the Attached Baselines and Baseline Groups.
If there are any missing patches, upgrades or updates the object will be in a Non-Compliant state. Once the Scan is complete, we can see the status of the Compliance check. We can see that this host as 57 patches that need to be applied with 8 critical and 3 security fixes.
Let's minimize the Recent tasks to proceed. A new feature in 6. This will detect and issues that may stop your remediation from completing successfully. Let's run the Pre-Check Remediation and see the results. Our Remediation Pre-Check has passed, as we have no outstanding issues.
Any errors that could impact remediation would be shown here such as DRS being disabled or attached removable media devices. Lets close the Remediation Pre-Check to proceed. We are now ready to proceed with Remediation. Lets select All baselines we wish to apply to our host. 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
