[<CommonParameters>] Description
The Add-AzVMDataDisk cmdlet adds a data disk to a virtual machine. You can add a data disk when you create a virtual machine, or you can add a data disk to an existing virtual machine.
Examples
Example 1: Add data disks to a new virtual machine
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine07" -VMSize "Standard_A1"
$DataDiskVhdUri01 = "https://contoso.blob.core.windows.net/test/data1.vhd"
$DataDiskVhdUri02 = "https://contoso.blob.core.windows.net/test/data2.vhd"
$DataDiskVhdUri03 = "https://contoso.blob.core.windows.net/test/data3.vhd"
$VirtualMachine = Add-AzVMDataDisk -VM $VirtualMachine -Name 'DataDisk1' -Caching 'ReadOnly' -DiskSizeInGB 10 -Lun 0 -VhdUri $DataDiskVhdUri01 -CreateOption Empty
$VirtualMachine = Add-AzVMDataDisk -VM $VirtualMachine -Name 'DataDisk2' -Caching 'ReadOnly' -DiskSizeInGB 11 -Lun 1 -VhdUri $DataDiskVhdUri02 -CreateOption Empty
$VirtualMachine = Add-AzVMDataDisk -VM $VirtualMachine -Name 'DataDisk3' -Caching 'ReadOnly' -DiskSizeInGB 12 -Lun 2 -VhdUri $DataDiskVhdUri03 -CreateOption EmptyThe first command creates a virtual machine object, and then stores it in the $VirtualMachine variable. The command assigns a name and size to the virtual machine. The next three commands assign paths of three data disks to the $DataDiskVhdUri01, $DataDiskVhdUri02, and $DataDiskVhdUri03 variables. This approach is only for readability of the following commands. The final three commands each adds a data disk to the virtual machine stored in $VirtualMachine. The command specifies the name and location for the disk, and other properties of the disk. The URI of each disk is stored in $DataDiskVhdUri01, $DataDiskVhdUri02, and $DataDiskVhdUri03.
Example 2: Add a data disk to an existing virtual machine
$VirtualMachine = Get-AzVM -ResourceGroupName "ResourceGroup11" -Name "VirtualMachine07"
Add-AzVMDataDisk -VM $VirtualMachine -Name "disk1" -VhdUri "https://contoso.blob.core.windows.net/vhds/diskstandard03.vhd" -LUN 0 -Caching ReadOnly -DiskSizeinGB 1 -CreateOption Empty
Update-AzVM -ResourceGroupName "ResourceGroup11" -VM $VirtualMachineThe first command gets the virtual machine named VirtualMachine07 by using the Get-AzVM cmdlet. The command stores the virtual machine in the $VirtualMachine variable. The second command adds a data disk to the virtual machine stored in $VirtualMachine. The final command updates the state of the virtual machine stored in $VirtualMachine in ResourceGroup11.
Example 3: Add a data disk to a new virtual machine from a generalized user image
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine07" -VMSize "Standard_A1"
$DataImageUri = "https://contoso.blob.core.windows.net/system/Microsoft.Compute/Images/captured/dataimage.vhd"
$DataDiskUri = "https://contoso.blob.core.windows.net/test/datadisk.vhd"
$VirtualMachine = Add-AzVMDataDisk -VM $VirtualMachine -Name "disk1" -SourceImageUri $DataImageUri -VhdUri $DataDiskUri -Lun 0 -DiskSizeinGB 10 -CreateOption FromImageThe first command creates a virtual machine object and stores it in the $VirtualMachine variable. The command assigns a name and size to the virtual machine. The next two commands assign paths for the data image and data disks to the $DataImageUri and $DataDiskUri variables respectively. This approach is used to improve the readability of the following commands. The final commands adds a data disk to the virtual machine stored in $VirtualMachine. The command specifies the name and location for the disk and other properties of the disk.
Example 4: Add data disks to a new virtual machine from a specialized user image
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine07" -VMSize "Standard_A1"
$DataDiskUri = "https://contoso.blob.core.windows.net/test/datadisk.vhd"
$VirtualMachine = Add-AzVMDataDisk -VM $VirtualMachine -Name "dd1" -VhdUri $DataDiskUri -Lun 0 -DiskSizeinGB 10 -CreateOption AttachThe first command creates a virtual machine object and stores it in the $VirtualMachine variable. The command assigns a name and size to the virtual machine. The next commands assigns paths of the data disk to the $DataDiskUri variable. This approach is used to improve the readability of the following commands. The final command add a data disk to the virtual machine stored in $VirtualMachine. The command specifies the name and location for the disk, and other properties of the disk.
Parameters
-Caching
Specifies the caching mode of the disk. The acceptable values for this parameter are:
- ReadOnly
- ReadWrite
- None 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: | CachingTypes |
| Accepted values: | None, ReadOnly, ReadWrite |
| Position: | 3 |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-CreateOption
Specifies whether this cmdlet creates a disk in the virtual machine from a platform or user image, creates an empty disk, or attaches an existing disk. The acceptable values for this parameter are:
- Attach. Specify this option to create a virtual machine from a specialized disk. When you specify this option, do not specify the SourceImageUri parameter. The VhdUri is all that is needed in order to tell the Azure platform the location of the virtual hard disk (VHD) to attach as a data disk to the virtual machine.
- Empty. Specify this to create an empty data disk.
- FromImage. Specify this option to create a virtual machine from a generalized image or disk. When you specify this option, you must specify the SourceImageUri parameter also in order to tell the Azure platform the location of the VHD to attach as a data disk. The VhdUri parameter is used as the location identifying where the data disk VHD will be stored when it is used by the virtual machine.
