  • Reference
Module:
Az.Compute

Modifies properties of a virtual machine data disk.

Syntax

Set-AzVMDataDisk
   [-VM] <PSVirtualMachine>
   [-Name] <String>
   [[-Caching] <CachingTypes>]
   [[-DiskSizeInGB] <Int32>]
   [-StorageAccountType <String>]
   [-DiskEncryptionSetId <String>]
   [-WriteAccelerator]
   [-DefaultProfile <IAzureContextContainer>]
   [<CommonParameters>]
Set-AzVMDataDisk
   [-VM] <PSVirtualMachine>
   [-Lun] <Int32>
   [[-Caching] <CachingTypes>]
   [[-DiskSizeInGB] <Int32>]

   [-DiskEncryptionSetId <String>]
   [-WriteAccelerator]
   [-DefaultProfile <IAzureContextContainer>]
   [<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-AzVM

The 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.

Example 2

Modifies properties of a virtual machine data disk. (autogenerated)

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.
