If pubset devices are assigned explicitly, this status is not changed when /ATTACH-DEVICE or /DETACH-DEVICE is used.
A pubset that is assigned implicitly can subsequently be assigned explicitly by means of /ADD-VM-DEVICES. If the device is subsequently detached by means of /DETACH-DEVICE in the guest system, this status does not change.
Implicitly assigned pubsets can also be removed explicitly from the VM by the VM2000 or VM administrator by means of /REMOVE-VM-DEVICES or /SWITCH-VM-DEVICES, see "Explicit pubset assignment and removal". After /SWITCH-VM-DEVICES the pubset is assigned explicitly to the new VM.
Explicit assignment of an attached pubset to the guest system can be converted to implicit assignment by means of /REMOVE-VM-DEVICES ..., FORCE=*NO(WAIT-FOR-UNASSIGN= *YES). Subsequent detachment by means of /DETACH-DEVICE in the guest system releases the pubset.
In the case of pubset reconfiguration, VM2000 automatically adapts the pubset’s assignment mode as required, see the section “Pubset reconfiguration”.
