About PowerCLI - Disk Space Utilization

[YanSi]

I use the following script to execute

# Establishing the connection to our vSphere object
$vm = Get-VM -Name "vm01-a"
$vmView = $vm | Get-View
# Creating a new PowerShell custom object to easily output properties
$output = New-Object -TypeName PSCustomObject
# Adding desired properties to the new PowerShell object
$diskCommit = $vmView.Storage.PerDatastoreUsage.Committed
$diskUncommit = $vmView.Storage.PerDatastoreUsage.Uncommitted
Add-Member -InputObject $output -MemberType NoteProperty -Name UsedSpaceGB -Value ($diskCommit /1GB)
Add-Member -InputObject $output -MemberType NoteProperty -Name ProvisionedSpaceGB -Value (($diskCommit + $diskUncommit) /1GB)
$diskKey = $vmView.LayoutEx.Disk.Key
$diskCapacity = $vmView.Config.Hardware.Device | Where-Object {$_.key -eq $diskKey} | Select-Object -ExpandProperty capacityInBytes
Add-Member -InputObject $output -MemberType NoteProperty -Name CapacityGB -Value ($diskCapacity /1GB)
Add-Member -InputObject $output -MemberType NoteProperty -Name GuestPath -Value $vmView.Guest.Disk.DiskPath
Add-Member -InputObject $output -MemberType NoteProperty -Name GuestCapacityGB -Value ($vmView.Guest.Disk.Capacity)
Add-Member -InputObject $output -MemberType NoteProperty -Name GuestFreeSpaceGB -Value ($vmView.Guest.Disk.FreeSpace)
# Viewing the output
$output | FL

get the following results:

PS C:\Users\Administrator> $output | FL

UsedSpaceGB        : 4.27435741666704
ProvisionedSpaceGB : 5.57904542703182
CapacityGB         : 5
GuestPath          : {/, /boot}
GuestCapacityGB    : {3743416320, 1063256064}
GuestFreeSpaceGB   : {1517223936, 887902208}

I don't know how to get an integer result（GuestCapacityGB \ GuestFreeSpaceGB etc.....），For example, press GB or MB

If use this code

# Establishing the connection to our vSphere object
$vm = Get-VM -Name "vm01-a"
$vmView = $vm | Get-View
# Creating a new PowerShell custom object to easily output properties
$output = New-Object -TypeName PSCustomObject
# Adding desired properties to the new PowerShell object
$diskCommit = $vmView.Storage.PerDatastoreUsage.Committed
$diskUncommit = $vmView.Storage.PerDatastoreUsage.Uncommitted
Add-Member -InputObject $output -MemberType NoteProperty -Name UsedSpaceGB -Value ($diskCommit /1GB)
Add-Member -InputObject $output -MemberType NoteProperty -Name ProvisionedSpaceGB -Value (($diskCommit + $diskUncommit) /1GB)
$diskKey = $vmView.LayoutEx.Disk.Key
$diskCapacity = $vmView.Config.Hardware.Device | Where-Object {$_.key -eq $diskKey} | Select-Object -ExpandProperty capacityInBytes
Add-Member -InputObject $output -MemberType NoteProperty -Name CapacityGB -Value ($diskCapacity /1GB)
Add-Member -InputObject $output -MemberType NoteProperty -Name GuestPath -Value $vmView.Guest.Disk.DiskPath
Add-Member -InputObject $output -MemberType NoteProperty -Name GuestCapacityGB -Value ($vmView.Guest.Disk.Capacity /1GB)
Add-Member -InputObject $output -MemberType NoteProperty -Name GuestFreeSpaceGB -Value ($vmView.Guest.Disk.FreeSpace /1GB)
# Viewing the output
$output | FL

will get the following results:

PS C:\Users\Administrator>

I don't know how to solve this problem

[LucD]

You can use the .NET Round method

-Value ([math]::Round($diskCommit /1GB,0))

PS C:\Users\Administrator>

 But can't make "GuestCapacityGB" and "GuestFreeSpaceGB" Value Work.I think ($vmView.Guest.Disk.Capacity)and($vmView.Guest.Disk.FreeSpace) maybe can not use the .NET Round method.

[LucD]

You are calling a .NET mehod, that is independent of the property.
Your parenthesis are placed incorrectly.

Add-Member -InputObject $output -MemberType NoteProperty -Name GuestFreeSpaceGB -Value ([math]::Round($vmView.Guest.Disk.FreeSpace/1MB,0))

PS C:\Users\Administrator>

After modification, the prompt is as follows：

InvalidOperation: Method invocation failed because [System.Object[]] does not contain a method named 'op_Division'.

I think it has something to do with $vmView.Guest.Disk.Capacity

[LucD]

The $vmView.Guest.Disk.FreeSpace property is an array.
You can't to a division to an array, you will have to do this separately for each element in the array

Thanks you very Much !

I saw this post solved my doubts
