The vSphere Update Manager configuration is the last step to perform in the VCSA 6.0 before applying patches or updates to ESXi hosts.
The configuration is made trough the vSphere Client that also in vSphere 6.0 has the duty to manage VUM.
VCSA 6.0: setup vSphere Update Manager - pt. 1
VCSA 6.0: install vSphere Client and VUM plugin - pt. 2
VCSA 6.0: configure vSphere Update Manager - pt. 3
To scan hosts or VMs for compliance, Baselines have to be attached to the Update Manager to properly scan the system.
Open the vSphere Client and select the Update Manger tab. Click on Attach link to attach the desired baselines.
Select default Patch Baselines then click on Attach button.
Click the Scan link to scan the hosts for compliance.
Select the options to scan the host for and click on Scan button.
Hosts are being scanned.
If one or more hosts are not compliant, a red circle is displayed to warn new patches are available to install.
To proceed with updates, you can Stage and Remediate available patches:
- Stage: available patches from VMware are downloaded from the Update Manager server to the ESXi hosts without applying the patches and extensions immediately. Staging patches speed up the remediation process since they are already available locally on the hosts.
- Remediate: patches are downloaded and installed in the selected host. You can stage patches before remediation to reduce host downtime.
The vSphere Web Client currently offers the possibility to attach the baselines and scan the environment only.
