    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存储体提供IP主机存取对于FC存储设备。IPS模块是DS-X9308-SMIP。它提供透明SCSI路由。使用iSCSI协议的IP主机能透明访问在IP主机在iSCSI协议数据单元的FC网络的SCSI (FCP)目标(PDU)发送SCSI命令集封装到在TCP/IP连接的一个MDS9000 IPS端口。在IPS模块上,连接提供以适当地配置的千兆以太网(GE)接口的形式。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。它提交FC目标到IP主机,好象物理目标本地附加对IP网络。

    通过IPS模块要求对存储设备的访问的每台iSCSI主机需要有安装的一兼容的iSCSI驱动。使用iSCSI协议, iSCSI驱动允许iSCSI主机传输SCSI请求和答复在IP网络。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。

    路由SCSI从IP主机到FC存储设备包括以下主要操作:

    • 传输iSCSI请求和答复在IP网络在主机和IPS模块之间。
    • 路由SCSI请求和答复在主机在IP网络和FC存储设备之间(转换iSCSI对FCP反之亦然)。此运输路线由IPS模块执行。
    • 传输FCP请求或答复在IPS模块和FC存储设备之间。
    默认情况下IP存储模块不导入FC目标到iSCSI。在IPS模块安排FC目标可用iSCSI创始者前,动态或静态映射必须配置。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。在此配置中您将参见静态映射示例。使用动态映射,每次iSCSI主机连接对IPS模块一个新的FC N端口创建,并且为此N端口和pWWNs分配的nWWNs可能不同的。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。静态映射在IPS模块可以用于访问有映射的访问控制和的LUN/根据创始者的pWWNs和nWWNs的屏蔽的配置的智能FC存储阵列。

    您能通过指定的IPS端口列表将是通告和指定iSCSI允许的发起者节点名列表控制对每个静态映射的iSCSI目标的访问访问它。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。在此配置默认区域为特定VSAN允许。IPS模块使用基于域名的iSCSI的节点和FC基于分区的访问控制列表在iSCSI发现和iSCSI会话创建时强制执行访问控制。

    • 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存储体创建一个FC虚拟N端口(N端口可能已经存在)此IP主机的并且执行由IP主机访问FC目标pwwn FCID的一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FCID由名称服务器返回,则iSCSI会话接受。否则,登录请求被拒绝。

    配置

    在此部分,您提交以信息配置MDS9216和Cisco iSCSI驱动Solaris的。

    网络图

    本文档使用下图所示的网络设置。

    配置

    本文档使用如下所示的配置。

    • Vuk (Windows服务器2003)

    • 坎特伯雷(MDS9216)

    Vuk (Windows服务器2003)
    初始配置任务包括以下操作:

    • 设置的MDS9000系列系统的iSCS Itarget IP地址驱动程序将访问。
    • 设置iSCSI目标认证用户用户名和密码。
    • 保存iSCSI目标配置和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:

    1. 作为有管理员权限的一个用户登录到计算机。

    2. 点击开始,指向设置,点击控制面板然后双击iSCSI设置

      Iscsi设置程序造成思科iSCSI设置成功2000/XP/2003对话框的能显示。

    3. 在Win 2000对话框的Cisco iSCSI设置,请配置SCSI路由实例的IP地址在MDS9000系列系统的如下:

      • 目标主机主机名/IP地址文本框,请键入SCSI路由实例的IP地址在MDS9000系列系统的。在本例中配置示例, IP地址是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。

    4. 单击保存并且退出。

    5. 重新启动计算机。
