In this post I will explain how to install this hotfix using the HVM (Horizon Version Manager) appliance.
!!BACK-UP!!
Please make sure that before you begin back-ups of the appliances are verified and tested.
Upload hotfix files
First, we need to upload the hotfix files towards one of the Appliances. I choose the HVM appliance. Uploading can be done by using WinSCP. Because you need to provide the path towards the Hotfix file you can upload the files anywhere as long as you have the proper permissions in that location. I choose for /tmp.
Copy the following files:
- dt-platform-20_2_0-update01_TA-DM.tgz
- dt-platform-20_2_0-update01_SP-RM.tgz
After the upload we need to make the hotfix files available in the Rundeck GUI.
Horizon DaaS Artifact Upload
Login to the Horizon Version Manager Rundeck GUI via the URL: https://<HVM IP>:4443 with username Rundeck and the password provided during OVA deployment.
Select Horizon-DaaS-Artifact -Upload

And select Upload Artifacts to Horizon Version Manager.

The following values need to be filled in:
Type | Value |
Artifact-Type | Select artifact type: Hotfixes or Install-Upgrade |
File | Absolute Path (UNIX) towards the update files. Multiple files are possible |
IP-Address | IP Address of the local machine from where files are being uploaded |
User-Name | User which exists on the local machine |
User-Password | Password for the local user |

Click Run Job Now.
Horizon DaaS HotFix Management
To double check if the hotfixes are now available go to Horizon-DaaS-HotFix-Management in the Rundeck GUI and click on job 1. Refresh Hotfix List than click on Run Job Now. The available Hotfixes will be shown.
Apply Hotfix to DaaS Management Appliances
Once the Hotfixes are available we can start to install them. In the Rundeck GUI go to Horizon DaaS HotFix Management menu and click on job 3. Apply Hotfix to DaaS Appliances. To following values need to be filled in
Type | Value |
ServiceProvider-IP | Provide the IP/FQDN of the primary Service Provider appliance |
ServiceProvider Appliance password | Service Provider appliance password for the Desktone user |
Domain-Name | NetBIOS name of the domain to which the SP is bound |
Domain-User | Domain User Account |
Domain-Password | Password for the Domain User |
Org-DaaS-Version | Select the DaaS version of the ORG for which the Hotfix will be applied |
Hotfix | Select the correct Hotfix from the list |
Force | Choose to force the installation |
Org-IDs | Choose the ORG ID you want to update. 1000 for the Service Provider ORG and 1001 and up for tenant environments |

Click Run Job Now.
Apply Hotfix to DaaS Tenant Appliances
For the tenant Appliances, you can repeat the same steps as above. However, you will need to choose the dt-platform-20_2_0-update01_TA-DM update file and choose the correct Org-ID.
Troubleshooting
When running into problems during one of the steps you could check or try the following:
- Reboot appliances
- Check if NTP is in sync
- Run the Job with debug output
- Check the hal.log on the HVM appliance
- Check the horizon-air-link on the HAL appliance
- Check if appliances are up and running with Detect Hotfixes On DaaS Appliances
Conclusion
Should you install the 9.0.1 update? In my opinion, YES!! The update contains security updates but also the Microsoft Teams plug-in is now supported.
If you are still on Horizon DaaS 8.0.1 it is recommended to upgrade towards Horizon DaaS 9.01. With the Horizon Version Manager (Rundeck) appliance VMware introduced an automated way of installing the Horizon DaaS platform and Hotfixes. This makes our lives much easier. If all information is present the installation of a hotfix can be done in a matter of minutes. Even upgrades can be done in a matter of hours instead of days. Saving a lot of time.
If you have any questions about the upgrade towards Horizon DaaS 9.x feel free to leave contact me with a comment
[UPDATE 02-11-2020 16:00]
When deploying a new tenant from within the Service Center please keep in mind that the update is not installed automatically. You still need to follow the process of updating a Tenant.
