在ASM下，要把HDD的VM轉換成SSD的VM步驟非常複雜。需要手工把Disk從普通儲存賬戶複製到高階儲存賬戶。再通過這個Disk建立VM。
目前在有了ASM到ARM的遷移工具，以及Managed Disk後，這個工作就簡單了。
下面將介紹如何實現從ASM的HDD VM遷移到ARM模式下的Managed Disk的SSD VM。
一 ASM下的VM遷移到ARM下
1 Cli版本
這個工作，可以用powershell或Azure xplate cli，我採用的cli：
C:\Users\hengwei>azure info: _ _____ _ ___ ___ info: /_\ |_ / | | | _ \ __| info: _ ___/ _ \__/ /| |_| | / _|___ _ _ info: (___ /_/ \_\/___|\___/|_|_\___| _____) info: (_______ _ _) _ ______ _)_ _ info: (______________ _ ) (___ _ _) info: info: Microsoft Azure: Microsoft's Cloud Platform info: info: Tool version 0.10.13
版本是0.10.13.
2 檢視VNet和VM資訊
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 10.0.0.0/8 1 data: hws2p China East Created 192.168.1.0/24 1 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-1 StoppedDeallocated China East mp-ngfwf-1.chinacloudapp.cn data: hws2p ReadyRole China East hws2p01.chinacloudapp.cn 192.168.1.4 info: vm list command OK
3 遷移
遷移分三步：
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
此時Vnet和VM都已經遷移到ARM模式下了。
二 把ARM模式下的VM轉換成Managed Disk
1 CLI版本
這個工作的Azure採用的是Azure CLI2.0版本
root@hw-surfacebook:~# az --version azure-cli (2.0.7)
2 檢視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 轉換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" }
此時，Disk已經是Managed Disk了。
4 檢視disk資訊
root@hw-surfacebook:~# az disk list -o table AccountType DiskSizeGb Location Name OwnerId ProvisioningState ResourceGroup TimeCreated OsType ------------- ------------ ---------- -------------------------------------- ------------------------------------------------------------------------------------------------------------------------------------- ------------------- ---------------- -------------------------------- -------- Standard_LRS 31 chinaeast hws2p_hws2p-hws2p-0-201706231030480950 /subscriptions/xxxx/resourceGroups/hws2p01-Migrated/providers/Microsoft.Compute/virtualMachines/hws2p Succeeded HWS2P01-MIGRATED 2017-06-23T10:45:15.240624+00:00
三 把VM的型號轉換成DS系列，把Disk轉換成SSD
1 VM型號轉換
root@hw-surfacebook:~# az vm resize -n hws2p -g hws2p01-migrated --size Standard_DS1 - Running .. \ Running .. {/ Finished .. "availabilitySet": null, "diagnosticsProfile": null, "hardwareProfile": { "vmSize": "Standard_DS1" }, "id": "/subscriptions/xxxx/resourceGroups/hws2p01-migrated/providers/Microsoft.Compute/virtualMachines/hws2p", "instanceView": null, "licenseType": null, "location": "chinaeast", "name": "hws2p", "networkProfile": { "networkInterfaces": [ { "id": "/subscriptions/xxxx/resourceGroups/hws2p01-Migrated/providers/Microsoft.Network/networkInterfaces/hws2p-PrimaryNic", "primary": true, "resourceGroup": "hws2p01-Migrated" } ] }, "osProfile": null, "plan": null, "provisioningState": "Succeeded", "resourceGroup": "hws2p01-migrated", "resources": null, "storageProfile": { "dataDisks": [], "imageReference": null, "osDisk": { "caching": "ReadWrite", "createOption": "attach", "diskSizeGb": null, "encryptionSettings": null, "image": null, "managedDisk": { "id": "/subscriptions/xxxx/resourceGroups/hws2p01-Migrated/providers/Microsoft.Compute/disks/hws2p_hws2p-hws2p-0-201706231030480950", "resourceGroup": "hws2p01-Migrated", "storageAccountType": null }, "name": "hws2p_hws2p-hws2p-0-201706231030480950", "osType": "Linux", "vhd": null } }, "tags": null, "type": "Microsoft.Compute/virtualMachines", "vmId": "3d7b7a7f-6271-4fa5-9f94-88711eb9db43" }
2 Disk轉換成SSD
az disk update -g hws2p01-Migrated -n hws2p_hws2p-hws2p-0-201706231030480950 --sku Premium_LRS { "accountType": "Premium_LRS", "creationData": { "createOption": "Import", "imageReference": null, "sourceResourceId": null, "sourceUri": "https://2mportalvhdsg0nfxclb1p0q.blob.core.chinacloudapi.cn/vhds/hws2p01-hws2p-2017-06-23.vhd", "storageAccountId": null }, "diskSizeGb": 31, "encryptionSettings": null, "id": "/subscriptions/xxxx/resourceGroups/hws2p01-Migrated/providers/Microsoft.Compute/disks/hws2p_hws2p-hws2p-0-201706231030480950", "location": "chinaeast", "name": "hws2p_hws2p-hws2p-0-201706231030480950", "osType": null, "ownerId": "/subscriptions/xxxx/resourceGroups/hws2p01-Migrated/providers/Microsoft.Compute/virtualMachines/hws2p", "provisioningState": "Succeeded", "resourceGroup": "hws2p01-Migrated", "tags": null, "timeCreated": "2017-06-23T10:45:15.240624+00:00", "type": "Microsoft.Compute/disks" }
3 檢視Disk資訊
root@hw-surfacebook:~# az disk list -o table AccountType DiskSizeGb Location Name OwnerId ProvisioningState ResourceGroup TimeCreated OsType ------------- ------------ ---------- -------------------------------------- ------------------------------------------------------------------------------------------------------------------------------------- ------------------- ---------------- -------------------------------- -------- Premium_LRS 31 chinaeast hws2p_hws2p-hws2p-0-201706231030480950 /subscriptions/xxxx/resourceGroups/hws2p01-Migrated/providers/Microsoft.Compute/virtualMachines/hws2p Succeeded HWS2P01-MIGRATED 2017-06-23T10:45:15.240624+00:00
已經是SSD的硬碟了。
四總結
通過ASM->ARM的轉換工具，可以方便的把ASM的VM遷移到ARM。
通過命令列方便的把disk遷移到Managed Disk。
在ARM中，可以在關機的狀態下resize VM到ssd型別的機器。
通過命令列，方便的把HDD的Disk轉換成SSD的Disk。
