A collection of virtual machines and ESXi hosts or individual inventory objects can be scanned for
compliance with a baseline or a baseline group and later remediated. You can initiate these processes
manually or through scheduled tasks.
n
Configuring the Update Manager Download Source
You can configure the Update Manager server to download patches and extensions either from the
Internet or from a shared repository. You can also import patches and extensions manually from a
ZIP file.
n
Downloading Updates and Related Metadata
Downloading 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.
n
Importing ESXi Images
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.
n
Creating Baselines and Baseline Groups
Baselines contain a collection of one or more patches, extensions, service packs, bug fixes, or
upgrades, and can be classified as patch, extension, or upgrade baselines. Baseline groups are
assembled from existing baselines.
n
Attaching Baselines and Baseline Groups to vSphere Objects
To use baselines and baseline groups, you must attach them to selected inventory objects such as
container objects, virtual machines, or hosts.
n
Scanning Selected vSphere Objects
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.
n
Reviewing Scan Results
Update Manager scans vSphere objects to determine how they comply with baselines and baseline
groups that you attach. You can filter scan results by text search, group selection, baseline selection,
and compliance status selection.
n
Staging Patches and Extensions to Hosts
You can stage patches and extensions before remediation to ensure that the patches and
extensions are downloaded to the host. Staging patches and extensions is an optional step that can
reduce the time during which hosts are in maintenance mode.
n
Remediating Selected vSphere Objects
Remediation is the process in which Update Manager applies patches, extensions, and upgrades to
ESXi hosts and virtual machines after a scan is complete.
