In this session, we will focus on patching an Esx host with a live demo showing how I patch 2 ESXi host.
Agenda
Step process for updating the Esxi host.
Configuration
Download the updates
Download the ISO to upgrade old host
Create a baseline or baseline group
Attach a baseline or baseline group
Scan a baseline
Review the Scan
Stage the patches
Remediate the patches.

The VMware Update Manager is built into the vCenter Server Appliance (VCSA) since 6.5
This is automatically enabled on the vCenter once it’s installed.
VUM allows you to Install ESX from version 6 to 6.5 or 6.5 to 6.7
VUM allows you to patch the ESXi host for a bug fix.

Note: it’s important to understand the patches so read the release notes before deploying it.

1. Configuration
   Configure the Update Manager Download sources
   Sources from the internet
   From a shared repository
   Manual upload ( import patches) and extensions pac files and zip files.
2. Download the updates
   Download the host patches extensions
   Default settings are VUM contacts, Vmware or third-party sources to gather the latest information (metadata) about available updates, patches and extensions
3. Import ISO to upgrade old Host
   You can upgrade the hosts in your environment to ESXi 6.7 by using host upgrade baselines.
   To create a host upgrade baseline, you must first upload at least one ESXi 6.7 .iso image to the Update Manager repository
4. Create baselines
   Baselines contain a collection of one or more patches, extensions, service packs, bug fixes, or upgrades, and can be classified as a patch, extension, or upgrade baselines.
   There are two types of baselines
   Baseline
   and
   Baseline Group
5. Attach a baseline to object
   To use baselines and baseline groups, you must attach them to selected inventory objects such as container objects, virtual machines, or hosts
6. Scan the vSphere Object
   Scanning is the process in which attributes of a set of hosts or virtual machines are evaluated against all patches, extensions, and upgrades from an attached baseline or baseline group, depending on the type of scan you select
7. Review the Scan
   Update Manager scans vSphere objects to determine how they comply with baselines and baseline groups that you attach.
8. Staging the patches and extension
   You can stage patches and extensions before remediation to ensure that the patches and extensions are downloaded to the host.
   Note: Staging patches and extensions is an optional step that can reduce the time during which hosts are in maintenance mode.
9. Remediate the patches
   Remediation is the process in which Update Manager applies for patches, extensions, and upgrades to ESXi hosts and virtual machines after a scan is complete.
