# Copyright (c) 2017 SUSE LINUX GmbH, Nuernberg, Germany.
|
|
#
|
|
# Configures a qeth 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:
|
|
# qeth_configure [-i] [-l] [-f -t <CARDTYPE> ] [-o "Values"] -n <portno> -p <portname> <read chan> <write chan> <data chan> <online>
|
|
#
|
|
# -i Configure IP takeover
|
|
# -l Configure Layer2 support
|
|
# -f Override safety checks
|
|
# -t Valid cardtypes are: qeth, hsi - Deprecated
|
|
# -o General QETH options, separated by spaces
|
|
# -n QETH port number to use, 0 or 1. Only needed for real, not virtual
|
|
# devices.
|
|
# -p QETH Portname to use - Deprecated. OSAs no longer need a port name.
|
|
# read/write/data chan = 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
|
|
#
|
|
# Return values:
|
|
# Return codes are determined by the chzdev command.
