When users try to check out desktops, the operations fail and an error message, No available Transfer Server, is displayed.

The check-out can fail when the operation is approximately 10% complete, before View Transfer Server begins transferring data to the client computer. The check-out can also fail later in the process. For example, the base image might be transferred to the client computer, but other virtual machine disks cannot be transferred.

This problem occurs with all check-out operations that are managed by a particular View Transfer Server instance.

This problem can occur because View Transfer Server is running on an ESX host that does not have access to the datastores where the desktops reside. During a check-out operation, View Transfer Server transfers desktop data from the datastores to the client computer. The datastores must be accessible from the ESX host where the View Transfer Server virtual machine is running.

Migrate the View Transfer Server virtual machine to an ESX host with access to the datastores.

a

In View Administrator, place the View Transfer Server instance in maintenance mode.

b

In vSphere Client, use the Migration wizard to migrate the View Transfer Server virtual machine to the destination ESX host.

c

In View Administrator, select the View Transfer Server instance and exit maintenance mode.

If you cannot migrate the View Transfer Server virtual machine, recreate View Transfer Server on another virtual machine on an ESX host with access to the datastores.

a

In View Administrator, remove the View Transfer Server instance from View Manager.

b

In vSphere Client, uninstall View Transfer Server or remove the View Transfer Server virtual machine.

c

Create a new virtual machine on the destination ESX host.

d

Install View Transfer Server on the virtual machine.

e

In View Administrator, add View Transfer Server to View Manager.
