Resolve errors for SKU not available

To determine which SKUs are available in a location or zone, use the az vm list-skus command.

az vm list-skus --location chinanorth3 --size Standard_D --all --output table

• --location filters output by location.
• --size searches by a partial size name.
• --all shows all information and includes sizes that aren't available for the current subscription.

ResourceType     Locations    Name               Zones    Restrictions
---------------  -----------  --------------     -------  --------------
virtualMachines  ChinaNorth3  Standard_D11_v2         1,2,3    None
virtualMachines  ChinaNorth3  Standard_D11_v2_Promo   1,2,3    None
virtualMachines  ChinaNorth3  Standard_D12_v2         1,2,3    None
virtualMachines  ChinaNorth3  Standard_D12_v2_Promo   1,2,3    None
virtualMachines  ChinaNorth3  Standard_D13_v2         1,2,3    None

Availability zones

You can view all the compute resources for a location's availability zones. By default, only SKUs without restrictions are displayed. To include SKUs with restrictions, use the --all parameter.

az vm list-skus --location chinanorth3 --zone --all --output table

ResourceType      Locations    Name                 Zones    Restrictions
----------------  -----------  -------------------  -------  --------------
disks             chinanorth3  Premium_LRS             1,2,3    None
disks             chinanorth3  Premium_LRS             1,2,3    None
disks             chinanorth3  Premium_LRS             1,2,3    None
disks             chinanorth3  Premium_LRS             1,2,3    None
disks             chinanorth3  Premium_LRS             1,2,3    None

You can filter by a resourceType like VMs for availability zones.

az vm list-skus --location chinanorth3 --resource-type virtualMachines --zone --all --output table

ResourceType      Locations    Name                 Zones    Restrictions
----------------  -----------  -------------------  -------  --------------
virtualMachines  ChinaNorth3  Standard_A1_v2          1,2,3    None
virtualMachines  ChinaNorth3  Standard_A2m_v2         1,2,3    None
virtualMachines  ChinaNorth3  Standard_A2_v2          1,2,3    None
virtualMachines  ChinaNorth3  Standard_A4m_v2         1,2,3    None
virtualMachines  ChinaNorth3  Standard_A4_v2          1,2,3    None

To determine which SKUs are available in a location or zone, use the Get-AzComputeResourceSku command.

Get-AzComputeResourceSku | Where-Object { $_.Locations -contains "chinanorth3" }

The Get-AzComputeResourceSku cmdlet gets all the compute resources. The objects are sent down the pipeline and Where-Object filters the output to include only the specified location. SKUs that aren't available for the current subscription are listed as NotAvailableForSubscription.

ResourceType                       Name    Location     Zones RestrictionInfo
------------                       ----    --------     ----- ---------------

disks                       Premium_LRS chinanorth3 {2, 3, 1}
disks                       Premium_LRS chinanorth3 {2, 3, 1}
disks                       Premium_LRS chinanorth3 {2, 3, 1}

The following PowerShell script filters by location and SKU:

$SubId = (Get-AzContext).Subscription.Id

$Region = "chinaeast2" # change region here
$VMSku = "Standard_M" # change VM SKU here

$VMSKUs = Get-AzComputeResourceSku | where {$_.Locations.Contains($Region) -and $_.ResourceType.Contains("virtualMachines") -and $_.Name.Contains($VMSku)}

$OutTable = @()

foreach ($SkuName in $VMSKUs.Name)
        {
            $LocRestriction = if ((($VMSKUs | where Name -EQ $SkuName).Restrictions.Type | Out-String).Contains("Location")){"NotAvailableInRegion"}else{"Available - No region restrictions applied" }
            $ZoneRestriction = if ((($VMSKUs | where Name -EQ $SkuName).Restrictions.Type | Out-String).Contains("Zone")){"NotAvailableInZone: "+(((($VMSKUs | where Name -EQ $SkuName).Restrictions.RestrictionInfo.Zones)| Where-Object {$_}) -join ",")}else{"Available - No zone restrictions applied"}


            $OutTable += New-Object PSObject -Property @{
                                                         "Name" = $SkuName
                                                         "Location" = $Region
                                                         "Applies to SubscriptionID" = $SubId
                                                         "Subscription Restriction" = $LocRestriction
                                                         "Zone Restriction" = $ZoneRestriction
                                                         }
         }

Availability zones

The following command only shows VM sizes for availability zones. SKUs that aren't available for the current subscription are listed as NotAvailableForSubscription.

Get-AzComputeResourceSku | Where-Object { $_.Locations -contains "chinanorth3" -and $_.LocationInfo.Zones -ne $null -and $_.ResourceType -eq "virtualmachines" }

ResourceType                      Name    Location     Zones RestrictionInfo
------------                      ----    --------     ----- ---------------
virtualMachines         Standard_A1_v2 ChinaNorth3 {1, 2, 3}
virtualMachines        Standard_A2m_v2 ChinaNorth3 {1, 2, 3}
virtualMachines         Standard_A2_v2 ChinaNorth3 {1, 2, 3}
virtualMachines        Standard_A4m_v2 ChinaNorth3 {1, 2, 3}
...
...

To determine which SKUs are available in a Region, use the portal. Sign in to the portal, and create a VM resource. You can select a Size with the drop-down menu of the available SKUs. You don't need to complete the deployment.

• To see other available sizes, select See all sizes.

  

• You can filter and scroll through the available sizes. When you find the VM size you want to use, choose Select.

  

To determine which SKUs are available in a location, use the Resource Skus - List operation.

You can use az rest to run the list operation. Replace <subscription ID> including the angle brackets with your subscription ID. The output is a large data set that you can save to a JSON file.

az rest --method get --uri https://management.chinacloudapi.cn/subscriptions/<subscription ID>/providers/Microsoft.Compute/skus?api-version=2021-07-01 --output-file .\sku-list.json

The command returns available SKUs and locations in JSON format:

    {
      "resourceType": "virtualMachines",
      "name": "Standard_A0",
      "tier": "Standard",
