Lets assume that you have a 3 years old storage and you are using it to place your virtual machines on Hyper-V Cluster. Then you bought a new storage box, you created LUNs on it and assign them as a CSV volumes on your existing Hyper-V Cluster. So next achievement would be migrating your virtual machines from old storage to new one.
That migration could be a headache if you have many VMs and many storage LUNs. So in that case, you can use following script to migrate Virtual Machines per CSV Volume. Just you need to specify which CSV volume you would like to drain. So let’s assume that volume is Volume1. I will specify that volume like following:
Start-CSVMigration -TargetVolume "Volume1" |
Start-CSVMigration -TargetVolume "Volume1" Now you need to specify other CSV Luns as well to filter them. Otherwise, you can migrate a VM to old storage again. So we are filtering them like following:
Start-CSVMigration -TargetVolume "Volume1" -FilteredVolumes "Volume2","Volume3","Volume4" |
Start-CSVMigration -TargetVolume "Volume1" -FilteredVolumes "Volume2","Volume3","Volume4" So how does it work?
We are creating an array called FilteredVolumes then adding our old storage luns to this array. You will see that I’m also adding $TargetVolume to same array. Because there is a chance to try to migrate a VM to same volume. So that will prevent that kind of issues.
So how can I get destination volume?
$FullQuery = '((Get-ClusterSharedVolume |' + $Query + ' Select -ExpandProperty SharedVolumeInfo | Select @{label="Name";expression={(($_.FriendlyVolumeName).Split("\"))[-1]}},@{label="FreeSpace";expression={($_ | Select -Expand Partition).FreeSpace}} | Sort FreeSpace -Descending)[0]).Name' |
$FullQuery = '((Get-ClusterSharedVolume |' + $Query + ' Select -ExpandProperty SharedVolumeInfo | Select @{label="Name";expression={(($_.FriendlyVolumeName).Split("\"))[-1]}},@{label="FreeSpace";expression={($_ | Select -Expand Partition).FreeSpace}} | Sort FreeSpace -Descending)[0]).Name' As you can notice from the code below, i’m getting all CSV volumes, filtering old storage volumes, sorting new storage CSVs by their free space and selecting the storage which has biggest available disk space.
So I’ll place VM into that volume:
Move-VMStorage -ComputerName "$ClusterNode" -VMName "$VMName" -DestinationStoragePath "C:\ClusterStorage\$Volume\$VMName" |
Move-VMStorage -ComputerName "$ClusterNode" -VMName "$VMName" -DestinationStoragePath "C:\ClusterStorage\$Volume\$VMName" You can also allow VMs with passthrough disks and vHBA. You just need to add -AllowPT switch.
Start-CSVMigration -TargetVolume "Volume1" -FilteredVolumes "Volume2","Volume3","Volume4" -AllowPT |
Start-CSVMigration -TargetVolume "Volume1" -FilteredVolumes "Volume2","Volume3","Volume4" -AllowPT This is what I use to filter VMs with vHBA:
Where {($_ | Select -expand FibreChannelHostBusAdapters) -eq $Null} |
Where {($_ | Select -expand FibreChannelHostBusAdapters) -eq $Null} If you get the idea, now I can share full script:

}
}
} It’s enough to run this script on one of the Cluster Node, so that will start migrating virtual machines. That will also give an output, so you will be able to see which VM you are migrating.
This is also an example how you can automate storage migrations:

} I hope you will find it useful. See you!

You can update all SCVMM agents with following script:
1
2
3
4
5
6
7
| $Credential = Get-SCRunAsAccount -Name "Domain_Account"
$HyperVHosts = Get-SCVMMManagedComputer
foreach ($HyperVHost in $HyperVHosts)
{
$ManagedComputer = Get-SCVMMManagedComputer -ComputerName $HyperVHost
Update-SCVMMManagedComputer -Credential $Credential -VMMManagedComputer $HyperVHost
} |
$Credential = Get-SCRunAsAccount -Name "Domain_Account"
$HyperVHosts = Get-SCVMMManagedComputer
foreach ($HyperVHost in $HyperVHosts)
{
$ManagedComputer = Get-SCVMMManagedComputer -ComputerName $HyperVHost
Update-SCVMMManagedComputer -Credential $Credential -VMMManagedComputer $HyperVHost
} That will update all Hyper-V hosts agents as soon as possible.

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 my notes and scripts for a Hyper-V Disaster Recovery with Storage Replication.
First script on Main Site, creates Volume identifiers under CSV Volumes. So after a Volume restore, we can restore Volume names with that index. Also scripts exports all virtual machine configs. That will make it easier to restore all Virtual Machines on Hyper-V.

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.

} That will move all virtual machines via Storage Live Migration into best available CSV volume.

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.
