Playing with Hyper-V v3 and Failover Cluster on PowerShell v3

Posted in Virtual Machine Manager, Windows Powershell, Windows Server | 1 Comment | 3,991 views | 25/08/2012 22:01

I’m re-coding PoSHStats for Cluster support. Currently it just supports standalone hosts, but i have to extend that support for cluster environments. So while i’m playing with Powershell, I want to add some of my codes.

Getting Hyper-V hostname:

$Hostname = gc env:computername

Getting Cluster name of your Hyper-V host:

$ClusterName = (Get-Cluster | Get-ClusterNode | where Name -eq $Hostname).Cluster.Name

Even better one for Hyper-V specifically:

$ClusterName = (@(Get-Cluster | Get-ClusterNode | where Name -eq $Hostname | Get-ClusterGroup | where GroupType -eq "VirtualMachine") | Select-Object -First 1).Cluster.Name

Also I see that this doesn’t work as expected on PowerShell v3, so don’t use something like this:

$ClusterName = @(Get-Cluster | Get-ClusterNode | where Name -eq $Hostname | Get-ClusterGroup | where GroupType -eq "VirtualMachine").Cluster.Name[0]

Getting all clustered virtual machines:

$VMs = Get-Cluster $ClusterName | Get-ClusterGroup | Where GroupType -eq "VirtualMachine" | Get-VM

Also you can extend your query for resource monitoring:

$VMs = Get-Cluster -Name $ClusterName | Get-ClusterGroup | Where GroupType -eq "VirtualMachine" | Get-VM | where ResourceMeteringEnabled -eq $True | Measure-VM

Getting free space of Cluster Shared Volume:

1
2
3

$CSVVolume = "Volume1"
$CSVDisk = Get-ClusterSharedVolume | Select -Expand SharedVolumeInfo | Where FriendlyVolumeName -match "$CSVVolume"					
[int]$HostDiskDriveFreeSpace = ([math]::round((($CSVDisk | Select -Expand Partition).FreeSpace / 1GB), 0))

Getting total disk space of Cluster Shared Volume:

1
2
3

$CSVVolume = "Volume1"
$CSVDisk = Get-ClusterSharedVolume | Select -Expand SharedVolumeInfo | Where FriendlyVolumeName -match "$CSVVolume"					
[int]$HostDiskSpace = ([math]::round((($CSVDisk | Select -Expand Partition).Size / 1GB), 0))

I’ll share more next days, keep watching..
