If this problem occurs during a replication, the status of the operation changes to Wait to resume backup. The
error message, This desktop has been modified at the datacenter. Please contact your system
administrator., is not displayed to the user.
Cause
When
a View desktop is checked out, a snapshot is taken in vCenter Server to preserve the state of the virtual
machine. The vCenter Server version of the desktop is locked so that no other users can access it.
This problem can occur if vSphere allows the datacenter copy of a virtual machine to be unlocked and then,
perhaps inadvertently, another process or person powers on the virtual machine. For example, a virtual
machine might be unlocked during a vCenter Server upgrade. The virtual machine in the datacenter and the
local desktop are no longer synchronized.
When a local mode operation is initiated or resumed, View detects that the virtual machine versions are not
synchronized and stops the operation.
Solution
You can recover the client version or vCenter Server version of the virtual machine, depending on the local
mode operation that was underway.
If a check-in or replication failed, recover the client version. You can use a vdmadmin -V command that reverts
the vCenter Server virtual machine to the snapshot that was taken during the last synchronization.
1 On the View Connection Server computer, open a command prompt and navigate to the C:\Program
Files\VMware\VMware View\Server\tools\bin directory.
2 Run the vdmadmin -V -recoverClientVM command.
For example: vdmadmin -V -recoverClientVM -d lmdtpool -m machine1
3 Instruct the user to start the check-in operation again.
If a check-out failed, recover the vCenter Server version. You can use a vdmadmin -V command that takes a new
snapshot of the vCenter Server virtual machine, deletes the old snapshot, and rolls back the virtual machine.
During a rollback, the local View desktop is discarded.
1 On the View Connection Server computer, open a command prompt and navigate to the C:\Program
Files\VMware\VMware View\Server\tools\bin directory.
2 Run the vdmadmin -V -recoverServerVM command.
For example: vdmadmin -V -recoverServerVM -d lmdtpool -m machine2
3 Instruct the user to start the check-out operation again.
In a special situation in which a desktop is fully checked out, and no check-in or replication was underway
when the vCenter Server virtual machine was opened, you might want to preserve both the client and vCenter
Server virtual machines. Perhaps valid, useful contents were created on both virtual machines. In vCenter
Server, you can clone the vCenter Server virtual machine to preserve an identical copy. Next, you can use the
vdmadmin command with the -V -recoverClientVM option to recover the client virtual machine.
For information about using the vdmadmin command with the -V option, see “Recovering a Local Desktop by
Using the -V Option When the Desktop Was Modified in the Datacenter,” on page 435.
