# Copyright (c) 2017 SUSE LINUX GmbH, Nuernberg, Germany.
|
|
#
|
|
# Configures a CTC device by calling the IBM-provided chzdev command.
|
|
# Whereas this script used to validate the parameters provided to it,
|
|
# we now rely on chzdev to do that instead. The script is intended only
|
|
# as a "translation layer" to provide backward compatability for older
|
|
# scripts and tools that invoke it.
|
|
#
|
|
# Usage:
|
|
# ctc_configure <read channel> <write channel> <online> [<protocol>]
|
|
#
|
|
# read/write channel = x.y.ssss where
|
|
# x is always 0 until IBM creates something that
|
|
# uses that number
|
|
# y is the logical channel subsystem (lcss) number.
|
|
# Most often this is 0, but it could be non-zero
|
|
# ssss is the four digit subchannel address of the
|
|
# device, in hexidecimal, with leading zeros.
|
|
# online = 0 to take the device offline
|
|
# 1 to bring the device online
|
|
# protocol = 0 Compatibility with peers other than OS/390®, or z/OS, for
|
|
# example, a z/VM TCP service machine. This is the default.
|
|
# 1 Enhanced package checking for Linux peers.
|
|
# 3 For compatibility with OS/390 or z/OS peers.
|
|
# 4 For MPC connections to VTAM on traditional mainframe
|
|
# operating systems.
|
|
#
|
|
# Return values:
|
|
# Return codes are determined by the chzdev command.
