Azure Script to find IAAS disk configurations

Question

Hi All,

I am trying to use below PS script to find out azure IAAS disk configuration including (LUN,Data Caching,IO,Bandwidth).

Connect-AzAccount  
  
Set-AzContext -Subscription 'SubName'  
  
$vm=Get-AzVM -ResourceGroupName ReGrpNAME -Name VMNAME  
  
$disks = $vm.StorageProfile.DataDisks  
  
foreach ($disk in $disks) {  
    $lun = $disk.Lun  
     $size = $disk.DiskSizeGB  
    $maxIops = $disk.IopsReadWrite  
    $maxThroughput = $disk.ThroughputReadWriteMBps  
    $hostCaching = $disk.Caching  
     Write-Output "LUN: $lun, Drive letter: $driveLetter, Storage type: $storageType, Size: $size GB, Max IOPS: $maxIops, Max throughput: $maxThroughput MB/s, Host caching: $hostCaching"  
}  
  

Unfortunately its not providing me with IOPS and Throughput. Any idea why is it so? LUN and drive letter are present in output.

Also do we have any scripts which can provide the same information just by giving vm name as parameter instead of passing subscription name and resource group name?

Thanks,
ACDBA

Hi, checkout the Get-PspAzManagedDiskInfo.ps1 - script found here: https://github.com/powershellpr0mpt/PSP-AzureInventory/blob/861aa2acd0e6108001330a646229f59a1043d0a4/PSP-AzureInventory/public/Get-PspAzManagedDiskInfo.ps1#L117

Its part of the PSP-AzureInventory module, which might be what you need: https://github.com/powershellpr0mpt/PSP-AzureInventory/tree/861aa2acd0e6108001330a646229f59a1043d0a4

By default, its grabbing all the disks, if you want to target specific disks - then you will need to enter the RG name etc.
