Azure PowerShell find LastOwnershipUpdateTime on disk

# Ensure you're connected to Azure
Connect-AzAccount

# Get the disk details with extended properties
$disk = Get-AzDisk -ResourceGroupName "YourResourceGroupName" -DiskName "YourDiskName"

# Check the LastOwnershipUpdateTime property
$disk.LastOwnershipUpdateTime

If the property isn't directly accessible, you can try using the underlying REST API call:

# Get the disk resource
$disk = Get-AzDisk -ResourceGroupName "YourResourceGroupName" -DiskName "YourDiskName"

# Use the full resource ID to fetch detailed properties
$detailedDisk = Invoke-AzRestMethod -Path "$($disk.Id)?api-version=2023-10-02" -Method GET

# Parse the response to extract LastOwnershipUpdateTime
$detailedProperties = $detailedDisk.Content | ConvertFrom-Json
$lastOwnershipUpdateTime = $detailedProperties.LastOwnershipUpdateTime

If you want to get this for multiple disks:

# List all disks in a resource group
$disks = Get-AzDisk -ResourceGroupName "YourResourceGroupName"

# Filter and display LastOwnershipUpdateTime
$disks | ForEach-Object {
    [PSCustomObject]@{
        DiskName = $_.Name
        LastOwnershipUpdateTime = $_.LastOwnershipUpdateTime
    }
}

A few important notes:

• Ensure you're using the latest Az.Compute module (version 9.0.0 or higher)
• Make sure you're authenticated with Connect-AzAccount
• Replace "YourResourceGroupName" and "YourDiskName" with your actual resource group and disk names
• The property might not be available on older disks or in all Azure regions
