目录

简介

Cisco的iSCSI驱动，在服务器上位于，是iSCSI解决方法的关键组件。这些iSCSI驱动程序会拦截SCSI命令，将其封装到IP数据包中，然后将其重定向到Cisco SN 5420、Cisco SN 5428-2或Cisco MDS/IPS-8。本文档提供Linux iSCSI主机到MDS的示例配置/IPS-8。

开始使用前 

规则

本文档中使用的Cisco MDS 9000是指MDS 9000系列(MDS 9506、MDS 9509、MDS 9216)中的任何光纤通道(FC)交换机产品。IPS刀片是指IP存储服务模块。有关文档规则的详细信息，请参阅 Cisco 技术提示规则。

先决条件

  • 在MDS 9000上开始进行iSCSI配置之前，您需要安装与Linux版本兼容的iSCSI驱动程序。该驱动程序的最新版本可在Cisco.com上的Cisco iSCSI Driver for Linux（仅限注册客户）页中找到。README.txt文件包括在驱动程序zip(tar)文件中。README包含关于许可证协议的信息、驱动程续安装和配置说明以及驱动体系结构的技术概要。

    本文档中的信息都是基于特定实验室环境中的设备创建的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您是在真实网络上操作，请确保您在使用任何命令前已经了解其潜在影响。

    背景理论

    IPS模块提供对FC存储设备的IP主机访问。IPS模块是DS-X9308-SMIP。它提供透明SCSI路由。使用iSCSI协议的IP主机可以透明地访问FC网络上的iSCSI目标IP主机通过TCP/IP连接将封装在iSCSI协议数据单元(PDU)中的SCSI命令发送到MDS 9000 IPS端口。在IPS模块上，以正确配置的千兆以太网接口形式提供连接。IPS模块使您创建虚拟iSCSI目标并且映射他们到在FC SAN上可用的物理FC目标。它将FC目标呈现给IP主机，就像物理目标连接到IP网络一样。

    需要通过IPS模块访问存储的每台iSCSI主机都需要安装兼容的iSCSI驱动程序。使用iSCSI协议， iSCSI驱动程序允许iSCSI主机通过IP网络传输SCSI请求和响应。从主机操作系统的角度， iSCSI驱动看来是SCSI运输驱动程序，与主机中一条外围通道的FC驱动程序相似。从存储设备的角度，每台IP主机出现为一台FC主机。

    将SCSI从IP主机路由到FC存储设备包括以下主要操作：

    • 在主机和IPS模块之间通过IP网络传输iSCSI请求和响应。

    • 在IP网络上的主机和FC存储设备之间路由SCSI请求和响应（将iSCSI转换为FCP，反之亦然）。 此运输路线由IPS模块执行。

    • 在IPS模块和FC存储设备之间传输FCP请求或响应。

    默认情况下，IPS模块不将FC目标导入iSCSI。在IPS模块使FC目标可用于iSCSI启动器之前，必须配置动态或静态映射。当两个都被配置后，静态被映射的FC目标有一个配置的名称。在此配置中，您将看到静态映射的示例。使用动态映射时，每次iSCSI主机连接到IPS模块时都会创建新的FC N端口，为此N端口分配的nWWN和pWWN可能不同。请使用静态映射方法，如果您需要iSCSI主机每次获得同样nWWN和pWWN，它接到IPS模块。静态映射可用于IPS模块，以访问具有基于启动器的pWWN和/或nWWN的访问控制和LUN映射/掩码配置的智能FC存储阵列。

    您可以通过指定将通告每个静态映射的iSCSI目标的IPS端口列表并指定允许访问该目标的iSCSI启动器节点名称列表来控制对每个静态映射的iSCSI目标的访问。FC基于分区的访问控制和基于ISCSI的访问控制是访问控制可以为iSCSI提供的二个机制。可以同时使用两个方法。在此配置中，已允许特定VSAN使用默认分区。IPS模块使用基于iSCSI节点名称的访问控制列表和基于FC分区的访问控制列表，以在iSCSI发现和iSCSI会话创建期间实施访问控制。

    • iSCSI发现：当iSCSI主机创建一个iSCSI发现会话并询问所有iSCSI目标时， IPS模块返回iSCSI目标列表此iSCSI主机允许基于接入控制策略的接入。

    • iSCSI会话创建：当IP主机启动iSCSI会话时， IPS模块验证指定的iSCSI目标(在会议登录请求)是否静态映射到目标，如果是，验证IP主机的iSCSI节点名是否允许访问目标。如果IP主机没有权限，其登录被拒绝。

    然后，IPS模块为此IP主机创建FC虚拟N端口（N端口可能已存在），并对IP主机正在访问的FC目标pWWN的FCID执行FC名称服务器查询。它使用IP主机虚拟N端口的pwwn作为名称服务器查询的请求方。因此，名称服务器执行的一次强制的pwwn区域查询并且回应查询。如果名称服务器返回FCID，则接受iSCSI会话。否则，登录请求被拒绝。

    配置

    本文档使用如下所示的配置。

    • sse-andres（Linux版本2.4.18-3）

    • 梵蒂冈(MDS 9216)

    sse-andres（Linux版本2.4.18-3）

    在Linux主机上，iscsi.conf需要修改。 

    [root@sse-andres etc]# cat /etc/iscsi.conf
# iSCSI configuration file - see iscsi.conf(5)

# Authentication Settings
# -----------------------
# You may configure a default Username and Password to use for CHAP
# authentication by specifying the Global username and password parameters
# in the format as mentioned below. These entries will need to precede any
# "DiscoveryAddress" entries if authentication needs to be enabled for all the
# iSCSI targets.
#
# Example:
#
#Username=alice
#Password=nty57nbe
# or
#OutgoingUsername=alice
#OutgoingPassword=nty57nbe
#
# The "OutgoingUsername" will specify the username to be sent to the target
# for login authentication. The "OutgoingPassword" is the CHAP secret password
# to be used when sending challenge responses to the target.
#
# You may configure CHAP authentication settings that will apply to every
# target discovered at a particular address by adding "OutgoingUsername=u"
# and "OutgoingPassword=p" entries indented below the "DiscoveryAddress"
# entry they apply to.
#
# Example:
#
#DiscoveryAddress=192.168.10.94

DiscoveryAddress=10.48.69.242 Continuous=yes
    !--- Configure the IP address of the GE interface that accepts iSCSI request from your host. # LUN Settings
# ------------
# The LUN settings can be specified per TargetName or for all the targets
# whose TargetNames are mentioned in the configuration file. If no TargetName
# is present in the configuration file, the lun(s) will be configured for
# all the available iSCSI targets.
# The LUN settings can be specified in the following 3 formats:-
# LUN=
        
        
          # LUNs= 
         
           # LUNs= 
          
            # # The range of luns to be configured can be specified using a hyphen. A comma # separated list of luns can also be used. # Example: # #LUN=35 #LUNs=39-47 #LUNs=200,49,0,31 
           LUNs=0-255 # # LUNs can be configured per TargetName as mentioned in the format below. # #TargetName=iqn.1987-05.com.cisco:00.0d1d898e8d66.t0 # LUNs=39-47 # Continuous Discovery settings # ----------------------------- # You can configure discovery session to be kept open by setting # "Continuous" key to "yes" (default setting). Set Continuous=no to close # the discovery session, once the discovery is over. # #Continuous=yes #Continuous=no # # This parameter can be specified per DiscoveryAddress configuration. # #DiscoveryAddress=10.77.13.52 # Continuous=yes
