end

#read_channel ⇒ String

For CCW devices and CCW group devices, this device ID is the device bus-ID.

The device bus-ID is of the format 0.<subchannel_set_ID>.<devno>, for example, 0.0.8000.

The qeth device driver requires three I/O subchannels for each HiperSockets CHPID or OSA-ExpressCHPID in QDIO mode.

One subchannel is for control reads, one for control writes, and the third is for data.

Examples:

enable a qeth interface (persistently)

chzdev --enable qeth 0.0.a000:0.0.a001:0.0.a002

Returns:

  • (String) —

    read bus id
