[<CommonParameters>] Description
The Set-AzVMDataDisk cmdlet modifies properties of a virtual machine data disk.
Examples
Example 1: Modify the caching mode of a data disk
$VM = Get-AzVM -ResourceGroupName "ResourceGroup11" -VMName "ContosoVM07"
Set-AzVMDataDisk -VM $VM -Name "DataDisk01" -Caching ReadWrite | Update-AzVMThe first command gets the virtual machine named ContosoVM07 by using Get-AzVM. The command stores it in the $VM variable. The second command modifies the caching mode for the data disk named DataDisk01 on the virtual machine in $VM. The command passes the result to the Update-AzVM cmdlet, which implements your changes. A change to the cashing mode causes the virtual machine to restart.

Set-AzVMDataDisk -Caching None -Lun 1 -VM <PSVirtualMachine>Parameters
-Caching
Specifies the caching mode of the disk. The acceptable values for this parameter are:
- ReadOnly
- ReadWrite The default value is ReadWrite. Changing this value causes the virtual machine to restart. This setting affects the consistency and performance of the disk.
