My name is Yusuf Ozturk. I’m a PowerShell MVP and a system engineer at the Cloud team of a private bank where we have biggest Hyper-V production environment in Turkey. Managing large virtualization environment could be a headache if you don’t do your growing plans well or if you are growing quickly than you are expected. Patching Microsoft Updates to your Hyper-V Clusters could be problematic if you face with following issues:
1. Don’t have enough memory
2. Don’t have enough disk space
That means, your cluster is over-committed..
Also this issues could increase your pain in this scenario:
1. VMs with large memory (like 64GB memory or more)
2. VMs with vHBA
3. VMs with Passthrough Disks
Because you should do a good planing if you have large VMs in a over-committed environment because migrating that VMs won’t be an easy job than you think. Also misconfigured SAN switches, WWN configurations etc could be a problem for VMs with vHBa. Also drivers and firmwares could cause some issues for vHBA. As my experience, best way for migrating a VM with vHBA is keeping that offline. Otherwise you can lose disk connectivity anyway and it could damage your system, even you can lose data. So using clustered vHBA VMs can increase your uptime but also prevents data lose.
For the Passthrough disks, Hyper-V always get some issues with PT disks, couldn’t handle it well. So Microsoft doesn’t recommend it anymore maybe they will stop support with vNext, who knows..
So with this scenarios, current built-in Cluster-Aware Updating (CAU) has some problems:
1. CAU doesn’t know your VMs with vHBA or PT, because Cluster is handling them..
2. CAU doesn’t know your memory issue
3. CAU doesn’t know your disk issue
4. CAU doesn’t know if VM has a large memory
That’s why you can see that, Cluster tries to send a VM with 64 GB memory into a Hyper-V host with 32 GB free memory. Because Cluster only checks free memory in Cluster nodes. So i re-imagined CAU and wrote my own CAU process. What I do in my scenarion:
1. I can suspend VMs with vHBA and PT disk unless Cluster Node is online. (This is my choice, you can always use Live migrations)
2. I know which Cluster node has largest free memory. But what I know more is, which VM has largest memory as well. So I start with largest memory footprint VM, migrate it to best Cluster node. After that I can start migrating low memory VMs into that Host because there are still some memory for VMs like 2 GB, 4 GB etc..
3. I don’t leave migrations to Cluster Management. I do my own migrations. So that will give me my own control mechanism and that will give me flexibility. I can set timeout for VM migrations, so if a VM could not migrate in timely fashion, I can migrate it offline..
This is my own steps. You can always edit my script for your own requirements. Now lets see my new CAU script:

You may want to check available Microsoft Updates on remote servers. This script will give you that info.

} So if you just type:
that will get Microsoft Updates on your local server.
If you want to get Microsoft Updates from remote server, then type like:
Get-MicrosoftUpdate -ComputerName "MyHyperVHost01" |
Get-MicrosoftUpdate -ComputerName "MyHyperVHost01" That will give you Reboot requirements as well.

You can install Microsoft Updates on your server by using following PowerShell script.
This script doesn’t reboot your server after Microsoft Update, even if patch requires reboot.
Instead, it gives you True/False result as an output, so you can reboot server by checking Update results.
So you can use this script to create your own Cluster Aware Update procedure.

} So if you just type:
that will install Microsoft Updates on your local server.
If you want to install Microsoft Updates on remote server, then type like:
Install-MicrosoftUpdate -ComputerName "MyHyperVHost01" |
Install-MicrosoftUpdate -ComputerName "MyHyperVHost01" If you use this function in a script, then you can suppress write-host outputs:
Install-MicrosoftUpdate -ComputerName "MyHyperVHost01" -SuppressMode |
Install-MicrosoftUpdate -ComputerName "MyHyperVHost01" -SuppressMode That will give you Reboot Status as a result.

This is an example for nxService of PowerShell DSC.
You will able to stop a service like postfix on Linux by using PowerShell DSC.

Sometimes, you may need to empty your CSV volume for a maintenance operation or due to a volume corruption.
So you can use this script if you need to drain all virtual machines and virtual disks from a CSV.

Your Hyper-V storage environment crashed and you restored it from a backup or volume snapshot or you want to restore all virtual machines to the Disaster Center via Storage Replication. You added new storage luns into Failover Cluster but CSV names are changed. In that case you may not be able to import Virtual Machines into Hyper-V quickly due to incorrect virtual disk paths.
This script will check all Virtual Machine configs and shows you which configuration is not correct.
Then you can fix it manually or you can fix it via this script.

| function Repair-VMConfig {

.SYNOPSIS
Function to repair Virtual Machine config after CSV volume path changes.
You should put a volume identifier into CSV volumes to be able to use this script.
Simply put a Volume1.CSV into Volume1 as a volume identifier.
.DESCRIPTION
In some cases, CSV volume names could be changed. So you may not start your virtual machines due to incorrect virtual disk paths.
This function is written to fix this issue. It finds all Virtual Machines configuration problems and shows you as a output.
If you use ApplyChanges switch, it stops all Hyper-V Management Services in all Cluster Nodes, backups VM configs and fix incorrect VM virtual disk paths. Restarts Hyper-V Management Services after changes.
You should put a volume identifier into CSV volumes to be able to use this script. Simply put a Volume1.CSV into Volume1 as a volume identifier.
.PARAMETER WhatIf
Display what would happen if you would run the function with given parameters.
.PARAMETER Confirm
Prompts for confirmation for each operation. Allow user to specify Yes/No to all option to stop prompting.
.EXAMPLE
Repair-VMConfig
Just shows VM configuration problems and do not take any action unless you add -ApplyChanges switch.
.EXAMPLE
Repair-VMConfig -ApplyChanges
Stops all Hyper-V Management Services in all Cluster Nodes, backups VM configs and fix incorrect VM virtual disk paths. Restarts Hyper-V Management Services after changes.
.INPUTS
ApplyChanges switch to apply changes on Virtual Machines.
.OUTPUTS
None

} You should add -ApplyChanges switch in order to confirm changes on virtual machine configs. That will backup all VM configs before modification. Also that will stop and start all Hyper-V Management Services in all cluster nodes due to changes on VM configs.

You can migrate selected Virtual Machines in a Hyper-V Cluster with following script.
That will migrate all virtual machines into target volume.
If target volume is not specified, it will look for best available CSV volume, and migrate virtual machine into that.
