#read_channelString

Most I/O devices on a s390 system are typically driven through the channel I/O mechanism.

The s390-tools provides a set of commands for working with CCW devices and CCW group devices, these commands use a device ID which is the device bus-ID

The device bus-ID is of the format 0.., for example, 0.0.8000.

The CTCM device driver requires two I/O subchannels for each interface, a read subchannel and a write subchannel

Returns:

  • (String)

    read device bus id
