Description

The Set-AzVMOSDisk cmdlet sets the operating system disk properties on a virtual machine.

Examples

Example 1: Set properties on a virtual machine from platform image

$AvailabilitySet = Get-AzAvailabilitySet -ResourceGroupName "ResourceGroup11" -Name "AvailabilitySet13" 
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine17" -VMSize "Standard_A1" -AvailabilitySetID $AvailabilitySet.Id 
Set-AzVMOSDisk -VM $VirtualMachine -Name "OsDisk12" -VhdUri "os.vhd" -Caching ReadWrite
$VirtualMachine = Set-AzVMOperatingSystem -VM $VirtualMachine -Linux -ComputerName "MainComputer" -Credential (Get-Credential) 
$VirtualMachine = Set-AzVMSourceImage -VM $VirtualMachine -PublisherName "Canonical" -Offer "UbuntuServer" -Skus "15.10" -Version "latest"
$VirtualMachine = Set-AzVMOSDisk -VM $VirtualMachine -Name "osDisk.vhd" -VhdUri "https://mystorageaccount.blob.core.windows.net/disks/" -CreateOption FromImage
New-AzVM -VM $VirtualMachine -ResourceGroupName "ResourceGroup11"

The first command gets the availability set named AvailabilitySet13 in the resource group named ResourceGroup11, and then stores that object in the $AvailabilitySet variable. The second 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 virtual machine belongs to the availability set stored in $AvailabilitySet. The final command sets the properties on the virtual machine in $VirtualMachine.

Example 2: Sets properties on a virtual machine from generalized user image

$AvailabilitySet = Get-AzAvailabilitySet -ResourceGroupName "ResourceGroup11" -Name "AvailabilitySet13" 
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine17" -VMSize "Standard_A1"
$VirtualMachine = Set-AzVMOperatingSystem -VM $VirtualMachine -Linux -ComputerName "MainComputer" -Credential (Get-Credential)
$VirtualMachine = Set-AzVMOSDisk -VM $VirtualMachine -Name "osDisk.vhd" -SourceImageUri "https://mystorageaccount.blob.core.windows.net/vhds/myOSImage.vhd" -VhdUri "https://mystorageaccount.blob.core.windows.net/disks/" -CreateOption fromImage -Linux
New-AzVM -VM $VirtualMachine -ResourceGroupName "ResourceGroup11"

The first command gets the availability set named AvailabilitySet13 in the resource group named ResourceGroup11 and stores that object in the $AvailabilitySet variable. The second 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 virtual machine belongs to the availability set stored in $AvailabilitySet. The final command sets the properties on the virtual machine in $VirtualMachine.

Example 3: Sets properties on a virtual machine from specialized user image

$AvailabilitySet = Get-AzAvailabilitySet -ResourceGroupName "ResourceGroup11" -Name "AvailabilitySet13" 
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine17" -VMSize "Standard_A1"
$VirtualMachine = Set-AzVMOSDisk -VM $VirtualMachine -Name "osDisk.vhd" -VhdUri "https://mystorageaccount.blob.core.windows.net/disks/" -CreateOption Attach -Linux
New-AzVM -VM $VirtualMachine -ResourceGroupName "ResourceGroup11"

The first command gets the availability set named AvailabilitySet13 in the resource group named ResourceGroup11 and stores that object in the $AvailabilitySet variable. The second 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 virtual machine belongs to the availability set stored in $AvailabilitySet. The final command sets the properties on the virtual machine in $VirtualMachine.

Example 4: Set the disk encryption settings on a virtual machine operating system disk

$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine17" -VMSize "Standard_A1"
$VirtualMachine = Set-AzVMOSDisk -VM $VirtualMachine -Name "OsDisk12" -VhdUri "os.vhd" -Caching ReadWrite -Windows -CreateOption "Attach" -DiskEncryptionKeyUrl "https://mytestvault.vault.azure.net/secrets/Test1/514ceb769c984379a7e0230bddaaaaaa" -DiskEncryptionKeyVaultId "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/myresourcegroup/providers/Microsoft.KeyVault/vaults/mytestvault"
New-AzVM -VM $VirtualMachine -ResourceGroupName " ResourceGroup11"

This example sets the disk encryption settings on a virtual machine operating system disk.

Parameters

-Caching

Specifies the caching mode of the operating system disk. Valid values are:

• ReadOnly
• ReadWrite The default value is ReadWrite. Changing the caching value causes the virtual machine to restart. This setting affects the performance of the disk.

Type:	Nullable<T>[CachingTypes]
Accepted values:	None, ReadOnly, ReadWrite
Position:	3
Default value:	None
Accept pipeline input:	False
Accept wildcard characters:	False

-CreateOption

Specifies whether this cmdlet creates a disk in the virtual machine from a platform or user image, or attaches an existing disk. Valid values 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. Instead, use the Set-AzVMSourceImage cmdlet. You must also use the use the Windows or Linux parameters to tell the azure platform the type of the operating system on the VHD. The VhdUri parameter is enough to tell the azure platform the location of the disk to attach.
• FromImage. Specify this option to create a virtual machine from a platform image or a generalized user image. In the case of a generalized user image, you also need to specify the SourceImageUri parameter and either the Windows or Linux parameters to tell the Azure platform the location and type of the operating system disk VHD instead of using the Set-AzVMSourceImage cmdlet. In the case of a platform image, the VhdUri parameter is sufficient.
• Empty.
