VDI on VSAN Upgrade – Part 3: Host Upgrade via Web Client

This week I am continuing where I left off in my VDI on VSAN upgrade. Last time I had patched the VUM server ready for the next part of the process which is updating the hosts! Nothing too detailed in this one and most vSphere admins will have seen this done many times. However, since Update Manger is now fully available in the web client, I thought I’d run through that process as it’s nice to see the new feature in action!

Upgrading ESXi Hosts

1. Login to the web client and navigate to the Update Manager Icon
ESXi1

2. Select the VUM server and then the manage tab to view the settings of your VUM server that was upgraded (as per my previous post in the series).
ESXi2

3. Select “ESXi Images” tab and “Import ESXi Image…”
ESXi3

4. At the prompt, browse to the ESXi 6.0U1 image that you have hopefully downloaded from the VMware site. Select Import.

5. When finished, you will see a success message, click Ok.
ESXi4

6. You will be prompted with a Create Host Upgrade Baseline prompt, name the baseline and give it a description. (This can be done manually but this process takes care of it for you).
ESXi6

7. Next, navigate to your cluster/host, Manage and Update Manger. Click “Attach a baseline”.

8. Select the upgrade baseline created previously and click ok.

9. Once complete, select the “Scan for Updates” option. Leave only the “Upgrades” box ticked.

10. When complete, select the Remediate option. Chose the new upgrade baseline that was created.

11. Select the host/cluster you want to update.

12. Accept the EULA.

13. I generally choose to ignore warnings about unsupported devices/datastores, up to you on this one!
ESXi12

14. Give the task a name, then chose the maintenance mode/cluser remediation options that are right for you. In my case I do not enable parrallel remediation as I’m patching a small 3 node VSAN cluster!

15. Click finish on the confirmation and VUM will patch your selected cluster/host(s).

Nice and simple! The next post in the series will detail upgrading the VSAN on-disk file format from v1 to v2.
