Description

The Add-AzVmssDataDisk cmdlet adds a data disk to the Virtual Machine Scale Set (VMSS) instance.

Examples

Example 1: Add a data disk

PS C:\> $vmss = New-AzVmssConfig -Location $Loc -SkuCapacity 2 -SkuName "Standard_A0" -UpgradePolicyMode "Automatic"
PS C:\> $vmss = Add-AzVmssDataDisk -VirtualMachineScaleSet $vmss -Name 'DataDisk1' -Lun 0 -Caching 'ReadOnly' -CreateOption Empty -DiskSizeGB 10 -StorageAccountType StandardLRS

This command adds an empty data disk to the VMSS object.
