转换 Azure 托管磁盘的磁盘类型

$diskName = 'yourDiskName'
# resource group that contains the managed disk
$rgName = 'yourResourceGroupName'
# Choose between Standard_LRS, StandardSSD_LRS, StandardSSD_ZRS, Premium_ZRS, and Premium_LRS based on your scenario
$storageType = 'Premium_LRS'
# Premium capable size 
$size = 'Standard_DS2_v2'

$disk = Get-AzDisk -DiskName $diskName -ResourceGroupName $rgName

# Get parent VM resource
$vmResource = Get-AzResource -ResourceId $disk.ManagedBy

# Stop and deallocate the VM before changing the storage type
Stop-AzVM -ResourceGroupName $vmResource.ResourceGroupName -Name $vmResource.Name -Force

$vm = Get-AzVM -ResourceGroupName $vmResource.ResourceGroupName -Name $vmResource.Name 

# Change the VM size to a size that supports Premium storage
# Skip this step if converting storage from Premium to Standard
$vm.HardwareProfile.VmSize = $size
Update-AzVM -VM $vm -ResourceGroupName $rgName

# Update the storage type
$disk.Sku = [Microsoft.Azure.Management.Compute.Models.DiskSku]::new($storageType)
$disk | Update-AzDisk

Start-AzVM -ResourceGroupName $vm.ResourceGroupName -Name $vm.Name

#resource group that contains the managed disk
rgName='yourResourceGroup'

#Name of your managed disk
diskName='yourManagedDiskName'

#Premium capable size 
#Required only if converting from Standard to Premium
size='Standard_DS2_v2'

#Choose between Standard_LRS, StandardSSD_LRS, StandardSSD_ZRS, Premium_ZRS, and Premium_LRS based on your scenario
sku='Premium_LRS'

#Get the parent VM Id 
vmId=$(az disk show --name $diskName --resource-group $rgName --query managedBy --output tsv)

#Deallocate the VM before changing the size of the VM
az vm deallocate --ids $vmId 

#Change the VM size to a size that supports Premium storage 
#Skip this step if converting storage from Premium to Standard
az vm resize --ids $vmId --size $size

# Update the SKU
az disk update --sku $sku --name $diskName --resource-group $rgName 

az vm start --ids $vmId 

执行以下步骤：

1. 登录到 Azure 门户。
2. 在“虚拟机”列表中选择 VM。
3. 如果该 VM 未停止，请在 VM“概述”窗格的顶部选择“停止”，然后等待该 VM 停止。
4. 在 VM 对应的窗格中，从菜单中选择“磁盘”。
5. 选择要转换的磁盘。
6. 从菜单选择“大小 + 性能”。
7. 将“帐户类型”从原始磁盘类型更改为所需的磁盘类型。
8. 选择“保存”并关闭磁盘窗格。

磁盘类型转换会瞬间完成。 可以在转换后启动 VM。

以下步骤假设你已经有一个快照。 若要了解如何创建快照，请参阅创建虚拟硬盘的快照。

1. 登录到 Azure 门户。
2. 选择顶部的搜索栏。 搜索并选择“磁盘”。
3. 选择“+创建”并填写详细信息。
4. 确保“区域”和“可用性”区满足高级 SSD v2 或超级磁盘的要求。
5. 对于“区域”，请选择与所拍摄快照相同的区域。
6. 对于“源类型”，请选择“快照”。
7. 选择创建的快照。
8. 选择“更改大小”，并为“存储类型”选择“高级 SSD v2”或“超级磁盘”。
9. 选择你希望磁盘具有的性能和容量。
10. 继续转到“高级”选项卡。
11. 为“逻辑扇区大小（字节）”选择 512。
12. 选择“查看 + 创建”，然后选择“创建”。
