To get the maximum size of VMDKs (Virtual Machine Disk) in a vCenter environment using PowerCLI and print the information to a file, you can use the following PowerShell script:
# Connect to the vCenter Server
Connect-VIServer -Server vcenter.example.com -User administrator -Password your_password
# Output file path to save the results
$outputFile = "C:\Path\To\Output\File.txt"
# Get all VMs in the vCenter
$allVMs = Get-VM
# Create an empty array to store the maximum VMDK sizes
$maxVmdkSizes = @()
# Loop through each VM and get the maximum size of its VMDKs
foreach ($vm in $allVMs) {
$vmdks = Get-HardDisk -VM $vm
$maxVmdkSizeGB = $vmdks | Measure-Object -Property CapacityGB -Maximum | Select-Object -ExpandProperty Maximum
$maxVmdkSizes += [PSCustomObject]@{
"VM Name" = $vm.Name
"Maximum VMDK Size (GB)" = $maxVmdkSizeGB
}
}
# Export the results to a CSV file
$maxVmdkSizes | Export-Csv -Path $outputFile -NoTypeInformation
# Disconnect from the vCenter Server
Disconnect-VIServer -Server vcenter.example.com -Confirm:$false
Write-Host "Maximum VMDK sizes have been saved to $outputFile."In this script, replace "vcenter.example.com" with the hostname or IP address of your vCenter Server. Also, provide the correct path for $outputFile to save the results.
The script connects to the vCenter Server using Connect-VIServer, retrieves all VMs using Get-VM, and then loops through each VM to get the VMDKs using Get-HardDisk. It calculates the maximum VMDK size in gigabytes (GB) using Measure-Object, stores the results in the $maxVmdkSizes array as a custom PowerShell object, and finally exports the results to a CSV file using Export-Csv.
The script then disconnects from the vCenter Server using Disconnect-VIServer. The maximum VMDK sizes for each VM are saved in the specified output file, and a message is displayed on the PowerShell console to indicate the completion of the script.
To get the maximum size VMDKs in a vCenter environment and print them to a file using Python, you’ll need to use the VMware vSphere API. We can achieve this by using the pyVmomi library, which is a Python SDK for the VMware vSphere API. First, you’ll need to install the pyVmomi library:
pip install pyVmomiNext, you can use the following Python script to connect to your vCenter server, retrieve the virtual machines, and find the largest VMDK size for each VM:
from pyVim.connect import SmartConnect, Disconnect
from pyVmomi import vim
import ssl
def get_max_vmdk_size(virtual_machine):
max_vmdk_size = 0
for device in virtual_machine.config.hardware.device:
if isinstance(device, vim.vm.device.VirtualDisk):
size_bytes = device.capacityInBytes
if size_bytes > max_vmdk_size:
max_vmdk_size = size_bytes
return max_vmdk_size
def main():
# Set your vCenter server details
vcenter_server = 'YOUR_VCENTER_SERVER'
username = 'YOUR_USERNAME'
password = 'YOUR_PASSWORD'
# Ignore SSL certificate verification
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_NONE
try:
# Connect to vCenter
service_instance = SmartConnect(host=vcenter_server, user=username, pwd=password, sslContext=context)
if not service_instance:
raise SystemExit("Unable to connect to vCenter server.")
# Get all virtual machines in the vCenter environment
content = service_instance.RetrieveContent()
container = content.rootFolder
viewType = [vim.VirtualMachine]
recursive = True
containerView = content.viewManager.CreateContainerView(container, viewType, recursive)
virtual_machines = containerView.view
# Find the maximum size VMDK for each virtual machine
vm_max_vmdk_sizes = {}
for virtual_machine in virtual_machines:
vm_max_vmdk_sizes[virtual_machine.name] = get_max_vmdk_size(virtual_machine)
# Print the results to a file
with open('max_vmdk_sizes.txt', 'w') as f:
for vm_name, max_vmdk_size in vm_max_vmdk_sizes.items():
f.write(f"{vm_name}: {max_vmdk_size / (1024 ** 3)} GB\n")
print("Maximum VMDK sizes saved to 'max_vmdk_sizes.txt'.")
except Exception as e:
print("Error:", e)
finally:
# Disconnect from vCenter
if service_instance:
Disconnect(service_instance)
if __name__ == "__main__":
main()Replace 'YOUR_VCENTER_SERVER', 'YOUR_USERNAME', and 'YOUR_PASSWORD' with your vCenter server details. The script will connect to your vCenter server, retrieve all virtual machines, find the largest VMDK size for each VM, and then print the results to a file named max_vmdk_sizes.txt in the same directory as the script. The VMDK sizes will be printed in gigabytes (GB).
