There are some disk operations you can do in Windows Server 2012 with PowerShell:

# Getting Disk Signature
Get-Disk | ft FriendlyName, Signature
 
# Add Disk Signatures into Array
$Signatures = "4D53465420202020E55D0891031DB04CB1F2B507ED9FDC88","4D53465420202020E55D0891031DB04CB1F2B507ED9FDC89"
 
# Making Them Online
foreach ($Signature in $Signatures)
{
	Get-Disk | Where {$_.Signature -eq $Signature} | Set-Disk -IsOffline $False
}
 
# Making Them Offline
foreach ($Signature in $Signatures)
{
	Get-Disk | Where {$_.Signature -eq $Signature} | Set-Disk -IsOffline $True
}

Get-Disk is not available in Windows Server 2008 R2, so you should go with WMI.

This is my cluster checklist script to verify many different components like Windows Updates, Hotfixes, 3Par installation, Driver information etc.

$MasterHotfixes = @((Get-Hotfix -ComputerName $MasterNode).HotFixID)
 
# Now we will use that master hotfixes to compare with others
$ClusterResults = (Get-Cluster | Get-ClusterNode | Select Name,@{label="HP WBEM";expression={$ServerName = $_.Name; $TestWBEM = (Get-Item "\\$ServerName\C$\Program Files\HPWBEM\Tools\HPWbemTestEvent.exe").Exists; if ($TestWBEM -eq $True) { $TestWBEM = "True"; $TestWBEM; } else { $TestWBEM = "False"; $TestWBEM; }}},@{label="3PAR Info";expression={$ServerName = $_.Name; $Test3PAR = (Get-Item "\\$ServerName\C$\Program Files (x86)\3PAR\HP 3PARInfo\HP3PARInfo.exe").Exists; if ($Test3PAR -eq $True) { $Test3PAR = "True"; $Test3PAR; } else { $Test3PAR = "False"; $Test3PAR; }}},@{label="QLogic Driver";expression={$ServerName = $_.Name; (Get-Item \\$ServerName\C$\Windows\System32\Drivers\ql2300.sys).VersionInfo.ProductVersion}},@{label="HP SATA Driver";expression={$ServerName = $_.Name; (Get-Item \\$ServerName\C$\Windows\System32\Drivers\HPCISSs2.sys).VersionInfo.ProductVersion}},@{label="Total Hotfixes";expression={(Get-Hotfix -ComputerName $_.Name).HotFixID.Count}},@{label="Missing Hotfixes";expression={$Hotfixes = @((Get-Hotfix -ComputerName $_.Name).HotFixID); $MissingHotfixes = (Compare-Object -ReferenceObject $MasterHotfixes -DifferenceObject $Hotfixes).InputObject; if ($MissingHotfixes) { $MissingHotfixes } else { $MissingHotfixes = "No missing updates"; $MissingHotfixes } }} | Sort Name)
 
$ClusterResults

I hope it also helps you.

This is very useful script to get missing updates from your cluster nodes. Just run this on one of your Cluster node. Make sure you run PowerShell as (Domain) Administrator. Otherwise you can’t query your Cluster.

# You can get hotfix IDs like this
$HotfixResults[0].'Missing Hotfixes'

You will see pretty nice output :)

This might be useful to get Cluster Shared Volume (CSV) information from your cluster. Just run this on one of your Cluster node. Make sure you run PowerShell as (Domain) Administrator. Otherwise you can’t query your Cluster.

1
(Get-ClusterSharedVolume | Select -ExpandProperty SharedVolumeInfo | Select @{label="Name";expression={(($_.FriendlyVolumeName).Split("\"))[-1]}},@{label="Free Space (GB)";expression={([math]::round(((($_ | Select -Expand Partition).FreeSpace)/ 1GB), 0))}},@{label="Percent Free (%)";expression={([math]::round((($_ | Select -Expand Partition).PercentFree), 0))}},@{label="Total Space (GB)";expression={([math]::round(((($_ | Select -Expand Partition).Size)/ 1GB), 0))}} | Sort Name)

You will see pretty nice output.

This might be useful to get memory information from your cluster nodes. Just run this on one of your Cluster node. Make sure you run PowerShell as (Domain) Administrator. Otherwise you can’t query your Cluster.

1
(Get-Cluster | Get-ClusterNode | Select Name,@{label="Free Memory (GB)";expression={([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).FreePhysicalMemory / 1MB), 0))}},@{label="Free Memory (%)";expression={([math]::round(([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).FreePhysicalMemory / 1MB), 0))/([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).TotalVisibleMemorySize / 1MB), 0))*100))}},@{label="Total Memory (GB)";expression={([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).TotalVisibleMemorySize / 1MB), 0))}} | Sort Name)

You will see pretty nice output.

I’ve wrote 2 useful commands to find available memory and storage volume.

Getting most available CSV Volume by storage free space:

1
((Get-ClusterSharedVolume | Select -ExpandProperty SharedVolumeInfo | Select @{label="Name";expression={(($_.FriendlyVolumeName).Split("\"))[-1]}},@{label="FreeSpace";expression={($_ | Select -Expand Partition).FreeSpace}} | Sort FreeSpace -Descending)[0]).Name

Getting most available Hyper-V host by memory availability:

1
((Get-Cluster | Get-ClusterNode | Select Name,@{label="FreeMemory";expression={([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).FreePhysicalMemory / 1KB), 0))}} | Sort FreeMemory -Descending)[0]).Name

You can use Get-Cluster $ClusterName for remote Cluster support.

You can create your own DeploymentConfigTemplate via Server Manager. You just need to export config.
