How to identify drive of Azure Virtual Machine with how it is shown at Azure Portal?

I am trying to identify which drive matches from Azure Virtual Machine with what is shown on the Azure Portal site.

I am trying to increase the size of one drive (H: drive) in VM from Azure Portal site.

This is how it shows up in VM:

This is how it shows up in Azure Portal site:
enter image description here

Where do I go about finding the right one to upgrade (from Azure Portal site)?

Currently, H: drive has 2 TB for the capacity, and I am trying to increase to 4 TB.

    The following solution might help you with finding out which LUN number correlates to your ‘H’ partition. It is not very optimized but after a quick test should yield the desired result.

    The commands are:

    Get-Disk
Get-Partition -DiskNumber 2
$mydisk = Get-Disk 2
$mydisk.Location

    The output should provide the LUN. DiskNumber 2 was arbitrarily chosen and you might have to try all disk numbers provided by "Get-Disk" to obtain the disk with the correct partition (or of course use some other method).

    See the image below for my results:

    This MS Learn article provides more information about the commands.
    Hopefully this helps.

    Kind regards

    I tried to reproduce the same in my environment to identify which drive matches from Azure Virtual Machine

    I have created azure virtual machine and attached a new disk like below.

    enter image description here

    In Disk management to make understand on your disk -> right click -> properties -> you can see LUN number -> in my case LUN8 is represent as disk 5

    enter image description here

    enter image description here

    My disk 4 is identify in E drive as LUN 7

    enter image description here

    Now in disk click on virtual disk. suppose You want to increase size of azure8 (my disk name)

    enter image description here

    If you click on 5 -> 5 is represent as disk 5 (G)drive as location on LUN 8 in my portal LUN 8 is azure8 disk name this way u can identify which drive is represent on which disk

    enter image description here

    Additionally, To note the drives while allocating volume I have added to remember 2s for disk2 for particular LUN
