How to configure System Center VMM Part 13 – Patching Hosts

Welcome back for Part 13 of this System Center VMM series, in this post I will talk to you about Configuring the Update server and how to patch your hosts

Now that we have created some baselines let’s look at how we can patch our Hyper-V servers.

Patching

Now that we have created some baselines let’s look at how we can patch our Hyper-V servers. Go to the Fabric page and choose a Host Group containing some servers. Then click on the compliance button on the top bar.

If you expand one of the nodes you will see that it has multiple Baselines to it, and that the Compliance status is Unknown. Click on the Scan button next to the Compliance button on the top bar and do a scan.

Once the scan has finished it will say Non Compliant if you have new patcehs to install. Expand one and see what it’s missing. You can click on Compliance Properties to see what patches it needs.

Now that you are ready to patch select the cluster or a single node, and clicl remediate.

Choose if you wan’t to live migrate or save state of VM’s and choose hosts to update.

Now it will start to evict VM’s off the first node and put that into maintenance mode, then patch, boot, and wait for storage sync jobs to finish on the S2D cluster

A patch job could fail, wich it did for me this time. It failed to reboot the host, as it lost connection with the Host. Or it could fail to evacuate a VM off the host, wich might happen from time to time.

The patch cycle continued and finished the last node. But it did not reboot the node it lost contact with. I had to do so manualy. After the node came back up. Do a new rescan and check if it’s still not compliant. If so do a new remediation of the host missing patches.

Stay tuned for the next post, where i will write about Hardware Profiles
