A Ddriver-model.rst11 All ccw devices are accessed via a subchannel, this is reflected in the
24 In this example, device 0815 is accessed via subchannel 0 in subchannel set 0,
25 device 4711 via subchannel 1 in subchannel set 0, and subchannel 2 is a non-I/O
26 subchannel. Device 1234 is accessed via subchannel 0 in subchannel set 1.
28 The subchannel named 'defunct' does not represent any real subchannel on the
29 system; it is a pseudo subchannel where disconnected ccw devices are moved to
31 former subchannel. The ccw devices will be moved again to a proper subchannel
32 if they become operational again on that subchannel.
57 There is also some data exported on a per-subchannel basis (see under
