在ASM下，要把HDD的VM转换成SSD的VM步骤非常复杂。需要手工把Disk从普通存储账户复制到高级存储账户。再通过这个Disk创建VM。
目前在有了ASM到ARM的迁移工具，以及Managed Disk后，这个工作就简单了。
下面将介绍如何实现从ASM的HDD VM迁移到ARM模式下的Managed Disk的SSD VM。
一 ASM下的VM迁移到ARM下
1 Cli版本
这个工作，可以用powershell或Azure xplate cli，我采用的cli：
C:\Users\hengwei>azure
info: _ _____ _ ___ ___
info: /_\ |_ / | | | _ \ __|
info: _ ___/ _ \__/ /| |_| | / _|___ _ _
info: (___ /_/ \_\/___|\___/|_|_\___| _____)
info: (_______ _ _) _ ______ _)_ _
info: (______________ _ ) (___ _ _)
info:
info: Microsoft Azure: Microsoft's Cloud Platform
info:
info: Tool version 0.10.
版本是0.10.13.
2 查看VNet和VM信息
C:\Users\hengwei>azure network vnet list
info: Executing command network vnet list
+ Looking up the virtual network sites
data: Name Location Affinity group State Address space Subnets count VPN Gateway address
data: ------ ---------- -------------- ------- -------------- ------------- -------------------
data: hwfgfw China East Created 10.0.0.0/
data: hws2p China East Created 192.168.1.0/
info: network vnet list command OK
C:\Users\hengwei>azure vm list
info: Executing command vm list
+ Getting virtual machines
data: Name Status Location DNS Name IP Address
data: ---------- ------------------ ---------- --------------------------- -----------
data: mp-ngfwf- StoppedDeallocated China East mp-ngfwf-.chinacloudapp.cn
data: hws2p ReadyRole China East hws2p01.chinacloudapp.cn 192.168.1.4
info: vm list command OK
3 迁移
迁移分三步：
C:\Users\hengwei>azure network vnet validate-migration hws2p
info: Executing command network vnet validate-migration
data: Information : Virtual Network hws2p is eligible for migration.
data: Information : Deployment hws2p in Cloud Service hws2p01 is eligible for migration.
data: Information : VM hws2p in Deployment hws2p within Cloud Service hws2p01 is eligible for migration.
info: network vnet validate-migration command OK C:\Users\hengwei>azure network vnet prepare-migration hws2p
info: Executing command network vnet prepare-migration
info: network vnet prepare-migration command OK C:\Users\hengwei>azure network vnet commit-migration hws2p
info: Executing command network vnet commit-migration
info: network vnet commit-migration command OK
此时Vnet和VM都已经迁移到ARM模式下了。
二 把ARM模式下的VM转换成Managed Disk
1 CLI版本
这个工作的Azure采用的是Azure CLI2.0版本
root@hw-surfacebook:~# az --version
azure-cli (2.0.)
2 查看VM
root@hw-surfacebook:~# az vm list -o table
Name ResourceGroup Location
--------- ---------------- ----------
hwmdt HWNAVS chinanorth
hwcisco CISCOROUTER chinaeast
hwazcopy HWAZCOPY chinaeast
hwmt HWMT chinaeast
hwmt02 HWMT chinaeast
hws2p HWS2P01-MIGRATED chinaeast
hwmysql01 HWWAF chinaeast
hwwaf02 HWWAF chinaeast
hwwaf03 HWWAF chinaeast
3 转换Disk
root@hw-surfacebook:~# az vm convert -n hws2p -g hws2p01-migrated
| Running ..
{| Finished ..
"endTime": "2017-06-23T10:45:42.174661+00:00",
"error": null,
"name": "fa343688-ba91-447b-b531-5ff983866f9a",
"startTime": "2017-06-23T10:44:57.245702+00:00",
"status": "Succeeded"
}
此时，Disk已经是Managed Disk了。
4 查看disk信息
root@hw-surfacebook:~# az disk list -o table
AccountType DiskSizeGb Location Name OwnerId ProvisioningState ResourceGroup TimeCreated OsType
------------- ------------ ---------- -------------------------------------- ------------------------------------------------------------------------------------------------------------------------------------- ------------------- ---------------- -------------------------------- --------
Standard_LRS chinaeast hws2p_hws2p-hws2p-- /subscriptions/xxxx/resourceGroups/hws2p01-Migrated/providers/Microsoft.Compute/virtualMachines/hws2p Succeeded HWS2P01-MIGRATED --23T10::15.240624+:
三 把VM的型号转换成DS系列，把Disk转换成SSD
1 VM型号转换
root@hw-surfacebook:~# az vm resize -n hws2p -g hws2p01-migrated --size Standard_DS1

已经是SSD的硬盘了。
四总结
通过ASM->ARM的转换工具，可以方便的把ASM的VM迁移到ARM。
通过命令行方便的把disk迁移到Managed Disk。
在ARM中，可以在关机的状态下resize VM到ssd类型的机器。
通过命令行，方便的把HDD的Disk转换成SSD的Disk。
