Modifies the host caching of an existing data disk on an Azure virtual machine.
[!INCLUDE rdfe-banner]
Set-AzureDataDisk [-HostCaching] <String> [-LUN] <Int32> -VM <IPersistentVM> [-Profile <AzureSMProfile>]
[-InformationAction <ActionPreference>] [-InformationVariable <String>] [<CommonParameters>]
Set-AzureDataDisk [-DiskName] <String> [-ResizedSizeInGB] <Int32> -VM <IPersistentVM>
[-Profile <AzureSMProfile>] [-InformationAction <ActionPreference>] [-InformationVariable <String>]
[<CommonParameters>]
The Set-AzureDataDisk cmdlet modifies the cache attributes of an existing data disk on an Azure virtual machine. Specify which data disk to update by its logical unit number (LUN).
PS C:\> Get-AzureVM "ContosoService" | Set-AzureDataDisk -VM "VirtualMachine07" -LUN 2 -HostCaching ReadOnly | Update-AzureVM
This command gets the virtual machines that run on the service named ContosoService by using the Get-AzureVM cmdlet. The command passes them to the current cmdlet by using the pipeline operator. That cmdlet sets the data disk at LUN 2 of the virtual machine named VirtualMachine07 to use ReadOnly host caching. The command updates the virtual machine to reflect your changes by using the Update-AzureVM cmdlet.
PS C:\> Get-AzureVM "ContosoService" -Name "VirtualMachine07" | Get-AzureDataDisk | Set-AzureDataDisk -HostCaching ReadWrite | Update-AzureVM
This command gets an object for the virtual machine named VirtualMachine07 on the ContosoService cloud service. The command passes it to the Get-AzureDataDisk cmdlet, which gets the data disks for that virtual machine. The current cmdlet then sets the host caching mode of each data disks to ReadWrite. The command updates the virtual machine to reflect your changes.
Specifies the name of the data disk configuration that this cmdlet modifies.
Type: String
Parameter Sets: Resize

Required: True
Position: 3
Default value: None
Accept pipeline input: False
Accept wildcard characters: FalseWarning
Disk Caching is not supported for disks 4 TiB and larger. If multiple disks are attached to your VM, each disk that is smaller than 4 TiB will support caching.
Changing the cache setting of an Azure disk detaches and re-attaches the target disk. If it is the operating system disk, the VM is restarted. Stop all applications/services that might be affected by this disruption before changing the disk cache setting. Not following those recommendations could lead to data corruption.
Specifies the host level caching settings of the disk. Valid values are:
- None
- ReadOnly
- ReadWrite
