Independent disks cannot be backed up with the virtual appliance when the virtual machine is turned on
This article applies to:
- Acronis Backup & Recovery 10 Advanced Server - Virtual Edition
- Acronis Backup & Recovery 11 Virtual Edition
- Acronis vmProtect 6
- You are using the Virtual Appliance (Acronis Agent for ESX/ESXi) to back up virtual machines;
- One or several of your virtual machines fail to be backed up, when they are turned on, with the following error:
Failed to open the virtual machine ([STORAGE] MyVm.vmx)
|Additional info: |--------------------|Error code: 103|Module: 83|LineInfo: a859dd78cc91dcb0|Fields: |
Message: Failed to open the virtual machine ([STORAGE] MyVm.vmx)
|--------------------|Error code: 103|Module: 83|LineInfo: a859dd78cc91dc87|Fields: |
Message: Cannot obtain information on the virtual machine's independent persistent disks because the machine is not powered off at the moment.
- If you open the ESX console and look into the properties of the virtual machine, you find that the machine is using a persistent disk:
There is no possibility to snapshot independent disks when they are turned on. This is an ESX limitation.
There are three possible workarounds:
- Do not use independent disks in your virtual machines, and change the existing disks into nonpersistent;
- Turn off the virtual machines that use persistent disks before you back them up;
- For Acronis Backup & Recovery: Install the Acronis Agent for Windows or Linux into the actual virtual machine, after which the machine will appear under Physical machines.
You may experience a similar issue with mapped raw disks. In this case, the first step to troubleshoot would be to try creating a snapshot the ESX console and see if it works.
