2. An UNASSIGN is issued to all tape devices that support ASSIGN/UNASSIGN
during the vary off process.
3. If the IBM Service Representative indicates that the service on a quiesced
device or set of devices is complete, but the control unit initiated resume did not
successfully vary the affected device(s) online, the FORCE operand may be
used to vary the device(s) back online.
4. The TEST operand provides the ability for a device that would not normally be
allowed online by CP, to be brought online in test mode so that it can be
attached to a virtual machine for the execution of diagnostics in problem
determination. For a device to be eligible for test mode, it must be predefined
either in the system configuration file or through a SET RDEVICE, as an
unsupported device.
