Make sure you have the latest Virtual Appliance hardware and that you have no more than two disks

This article applies to:

• Acronis Backup & Recovery 11 Virtual Edition

Symptoms

1. You have upgraded the Acronis Agent for ESX(i) (Virtual Appliance) from Acronis Backup & Recovery 10 to Acronis Backup & Recovery 11;

   See also Acronis Backup & Recovery 11: Upgrading Virtual Appliance via vCenter Fails.

2. After the upgrade, the backup and recovery tasks fail with the following errors:

   Internal error: Attempt to access emulated disk for non-initialized object
   Failed to open raw hard disk data file
   Awaiting task 'AttacScsiHardDisk' has failed. Reason: Invalid configuration for device '0'

Cause

There are several causes:

• The Virtual Appliance hardware should be the latest version;
• The Acronis Agent for ESX(i) supports no more than two disks in a virtual appliance;
• There should be one controller with the bus logic parallel type and one with the lsi logic parallel type.

Solution

To resolve the issue, do the following:

1. Upgrade the virtual appliance hardware to the latest (7th) version using the Upgrade Virtual Hardware command in the vSphere Client;
2. If the virtual appliance has more than two disks, leave the first two disks and remove the rest from the Virtual Machine Properties dialog. Acronis Backup & Recovery 11 supports up to two disks in a virtual appliance;
3. Change the second SCSI controller type to lsi logic parallel. There should be one controller with the bus logic parallel type and one with the lsi logic parallel type;
4. Reboot the virtual appliance.
