TheVM/370 control program destages any changed cylinders on a volume
at detach time when the user count for the entire volume goes to zero.
Destaging is accomplished when CP issues a relinquish order to theMSS via the central server application program (DMKMSS). A relinquish order
is issued at detach time for volids mounted onSYSVIRT virtual unit
addresses andVIRTUAL virtual unit addresses. This is the case only
when the volume was mounted by the control program on behalf of the
guest operating system. Refer to the Generation Guide that identifies VS1/VS2 APARs to be applied to the central-server--virtual machine operating system to support the VM/370 relinquish function (APAR 11344).
