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驱动程序拦截SCSI命令，将其封装到IP数据包中，并将其重定向到Cisco SN 5420、Cisco SN 5428-2或Cisco MDS/IPS-8。本文档提供了Solaris iSCSI主机到MDS的示例配置/IPS-8。

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 IP存储模块提供对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SCSI(FCP)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(GE)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，就像物理目标在本地连接到IP网络一样。

需要通过IPS模块访问存储的每个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IP存储模块不导入FC目标到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。 IP存储模块为此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 在本节中，您将获得配置MDS 9216和Cisco iSCSI Driver for Solaris的信息。

保存iSCSI目标配置并设置驱动程序的启动类型。 要配置驱动程序，请执行以下步骤：

作为有管理员权限的一个用户登录到计算机。

单击开始，指向设置，单击控制面板，然后双击iSCSI配置。

Iscsi Config程序会显示Win 2000/XP/2003的Cisco iSCSI配置对话框。

在Win 2000的思科iSCSI配置对话框中，配置MDS 9000系列系统中SCSI路由实例的IP地址，如下所示：

在目标主机名/IP地址文本框中，键入MDS 9000系列系统中SCSI路由实例的IP地址。在本配置示例中，IP地址为10.48.69.222。

单击 Add。IP地址在Target Host Names/IP Addresses文本框下的显示区被显示。

点击保存并退出。

重新启动计算机。
