Set-AzureRmVMDataDisk

Modifies properties of a virtual machine data disk.

Syntax

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

Description

The Set-AzureRmVMDataDisk cmdlet modifies properties of a virtual machine data disk.

Examples

Example 1: Modify the caching mode of a data disk

PS C:\> $VM = Get-AzureRMVM -ResourceGroupName "ResourceGroup11" -VMName "ContosoVM07"
PS C:\> Set-AzureRmVMDataDisk -VM $VM -Name "DataDisk01" -Caching ReadWrite | Update-AzureRmVM

The first command gets the virtual machine named ContosoVM07 by using Get-AzureRmVM. 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-AzureRmVM cmdlet, which implements your changes. A change to the cashing mode causes the virtual machine to restart.

Required Parameters

-Lun

Specifies the logical unit number (LUN) of the data disk that this cmdlet modifies.

Type:System.Nullable`1[System.Int32]
Position:1
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-Name

Specifies the name of the data disk that this cmdlet modifies.

Type:String
Position:1
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-VM

Specifies the virtual machine for which this cmdlet modifies a data disk. To obtain a virtual machine object, use the Get-AzureRmVM cmdlet.

Type:PSVirtualMachine
Aliases:VMProfile
Position:0
Default value:None
Accept pipeline input:True (ByPropertyName, ByValue)
Accept wildcard characters:False

Optional 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.
Type:System.Nullable`1[Microsoft.Azure.Management.Compute.Models.CachingTypes]
Parameter Sets:None, ReadOnly, ReadWrite
Position:2
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-DefaultProfile

The credentials, account, tenant, and subscription used for communication with azure.

Type:Microsoft.Azure.Commands.Common.Authentication.Abstractions.IAzureContextContainer
Aliases:AzureRmContext, AzureCredential
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-DiskSizeInGB

Specifies the size, in gigabytes, for the data disk.

Type:System.Nullable`1[System.Int32]
Position:3
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-StorageAccountType

The virtual machine managed disk's account type.

Type:String
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-WriteAccelerator

Specifies whether WriteAccelerator should be enabled or disabled on the data disk.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
