Description

The New-AzureRmVMDataDisk cmdlet creates a local data disk object for a virtual machine or a Vmss VM.

Examples

Example 1: Add a managed data disk to a Vmss VM.

PS C:\> $disk = Get-AzureRmDisk -ResourceGroupName $rgname -DiskName $diskname0
PS C:\> $datadisk = New-AzureRmVMDataDisk -Caching 'ReadOnly' -Lun 2 -CreateOption Attach -StorageAccountType Standard_LRS -ManagedDiskId $disk.Id
PS C:\> $VmssVM = Get-AzureRmVmssVM -ResourceGroupName "myrg" -VMScaleSetName "myvmss" -InstanceId 0
PS C:\> Update-AzureRmVmssVM -ResourceGroupName "myrg" -VMScaleSetName "myvmss" -InstanceId 0 -DataDisk $datadisk

The first command gets an existing managed disk. The next command creates a data disk object with the managed disk. The next command gets an existing Vmss VM given by the resource group name, the vmss name and the instance ID. The final command updates the Vmss VM by adding a new data disk.
