Azure ARM Template add second disk - json

Question

I would like to add in my template option for second disk based from "userImageStorageAccountName" My template was wrking until ii try to add second disk then when I try to deploy Vm i receive:
Blockquote {"code":"StorageAccountAlreadyExists","message":"The storage account named TEST already exists under the subscription."}}
But my target is to create in that storage account i don't want to create new storage account
BTW do you have maybe a nice documentation to create template for dummies :D

thx for Help

Answer 1

Looking over the JSON, you are requesting platform to ask user to provide a new storage account. To use exiting storage account you can refer existing parameter to you have already provided .
Original JSON :
"dataDisk1VhdName": "[concat('http://',variables('storageAccountName'),'.blob.core.windows.net/',variables('vmStorageAccountContainerName'),'/',variables('vmName'),'dataDisk1.vhd')]"
Suggested JSON
"dataDisk1VhdName": "[concat('http://',parameters('userImageStorageAccountName'),'.blob.core.windows.net/',variables('vmStorageAccountContainerName'),'/',variables('vmName'),'dataDisk1.vhd')]"
Hope this helps.

Check if the storage account tags have been changed through the Azure/PowerShell portal by somebody else, and are different than the ones specified on the ARM template.
Sounds like a bug on the ARM deployment system, tags should be able to be updated but it is currently failing for storage account resources.
