# Copyright (c) 2017 SUSE LINUX GmbH, Nuernberg, Germany.
|
|
#
|
|
# Configures a zfcp host adapter 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:
|
|
# zfcp_host_configure <ccwid> <online>
|
|
#
|
|
# ccwid = 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 codes
|
|
# Return codes are determined by the chzdev command.
