Releasing vDisk locks

Since multiple target devices and Citrix Provisioning servers can gain access to a single vDisk image file, it is necessary to control access to prevent corruption of the image. Should a user accidentally assign a private image to multiple target devices, and then try to boot those target devices, a corrupt image would result. Therefore, the image becomes locked appropriately for a given configuration. The locked vDisk icon appears with a small lock on it.

Under certain circumstances these locks are not be released properly. A lock on a vDisk image is not released properly when a target device machine is booted from a vDisk, and then fails (or power is lost). If the same target device boots again, the same lock is used and no problem occurs. However, if an administrator tries to mount the drive on the provisioning server after the target device has failed, the server will not be able to mount that vDisk because a lock is still held by the failed target device. The administrator can release these locks.


Ensure that the vDisk is not in use before removing a lock. Removing a lock for a vDisk, which is in use, could corrupt the image.

To release select vDisk locks

  1. In the Citrix Provisioning console, right-click on the vDisk for which you want to release locks, and then select the Manage Locks option. The Manage VDisk Locks dialog appears.
  2. If a vDisk has a target device lock on it, that target device name appears in the dialog’s list. Select one or more target devices from the list, then click Remove lock. You can also choose Select All to remove all target device locks on the selected vDisk.
  3. Click Close to close the dialog.
