簡介

駐留在伺服器上的思科iSCSI驅動程式是iSCSI解決方案的關鍵元件。這些iSCSI驅動程式擷取Small Computer System Interface(SCSI)命令，將其封裝到IP資料包中，並將其重定向到Cisco SN 5420、Cisco SN 5428、Cisco SN 5428-2或Cisco MDS/IPS-8.This文檔，該文檔提供了HP-UX iSCSI主機到SN 5428的示例配置。

必要條件

需求

嘗試此組態之前，請確保符合以下要求：

安裝與HP-UX版本相容的iSCSI驅動程式。最新版本的驅動程式可在Cisco.com上的Cisco iSCSI驅動程式(僅限註冊客戶)下載頁面上找到。README.txt檔案包含在驅動程式zip(tar)檔案中。自述檔案包含有關許可證協定、驅動程式安裝和配置說明以及驅動程式體系結構技術概述的資訊。
在Cisco iSCSI Driver for HP-UX Release Notes的系統要求一節中介紹了作業系統要求和修補程式要求。

採用元件

本文中的資訊係根據以下軟體和硬體版本：

含兩個處理器的HP-UX 9000/800 A500伺服器。

註：在本實驗設定中，沒有用於iSCSI的獨立乙太網介面卡，且正在使用的介面卡為100 Mb。在任何現實環境中，您都有單獨的千兆乙太網(GE)介面卡作為iSCSI啟動器。

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

慣例

本文中所用的Cisco MDS 9000是指MDS 9000系列(MDS 9506、MDS 9509、MDS 9216)中的任何光纖通道(FC)交換機產品。思科入侵防禦系統(IPS)刀片指的是IP儲存服務模組。如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

背景資訊

思科入侵防禦系統(IPS)模組為IP主機提供對光纖通道(FC)儲存裝置的訪問。IPS模組是DS-X9308-SIMP。它提供透明的SCSI路由。使用iSCSI協定的IP主機可以透明地訪問FC網路上的iSCSI目標IP主機通過TCP/IP連線將封裝在iSCSI協定資料單元(PDU)中的SCSI命令傳送到MDS 9000 IPS埠。在IPS模組上，連線以正確配置的GE介面的形式提供。IPS模組使您能夠建立虛擬iSCSI目標並將它們對映到FC SAN中可用的物理FC目標。它向IP主機顯示FC目標，就像物理目標已連線到IP網路一樣。

需要通過IPS模組訪問儲存裝置的每個iSCSI主機都需要安裝相容的iSCSI驅動程式。藉助iSCSI協定，iSCSI驅動程式允許iSCSI主機通過IP網路傳輸SCSI請求和響應。從主機作業系統的角度來看，iSCSI驅動程式似乎是SCSI傳輸驅動程式，類似於主機中外圍通道的FC驅動程式。從儲存裝置的角度來看，每個IP主機都顯示為FC主機。將SCSI從IP主機路由到FC儲存裝置包含以下主要操作：

通過IP網路在主機和IPS模組之間傳輸iSCSI請求和響應
在IP網路上的主機和FC儲存裝置之間路由SCSI請求和響應（將iSCSI轉換為FCP，將FCP轉換為iSCSI）。此路由由IPS模組執行。
在IPS模組和FC儲存裝置之間傳輸FCP請求或響應

預設情況下，IPS模組不會將FC目標匯入iSCSI。在IPS模組使FC目標可用於iSCSI啟動器之前，必須配置動態或靜態對映。當兩者都配置時，靜態對映的FC目標具有已配置的名稱。本文提供靜態對映的示例。使用動態對映時，每次iSCSI主機連線到IPS模組時，都會建立一個新的FC N埠，並為此N埠分配的nWWN和pWWN可能不同。如果需要在iSCSI主機每次連線到IPS模組時獲得相同的nWWN和pWWN ，請使用靜態對映方法。可以在IPS模組上使用靜態對映來訪問智慧FC儲存陣列，這些儲存陣列具有基於啟動器的pWWN或nWWN的訪問控制和邏輯單元號(LUN)對映和掩蔽配置。

您可以通過建立目標通告所在的IPS埠的特定清單以及建立允許訪問目標的iSCSI啟動器節點名稱清單來控制對每個靜態對映的iSCSI目標的訪問。基於FC分割槽的訪問控制和基於iSCSI的訪問控制是為iSCSI提供訪問控制的兩種機制。這兩種方法可以同時使用。在此配置中，允許特定VSAN的預設分割槽。IPS模組使用基於iSCSI節點名稱的訪問控制清單和基於FC分割槽的訪問控制清單，在iSCSI發現和iSCSI會話建立期間實施訪問控制。

iSCSI發現：當iSCSI主機建立iSCSI發現會話並查詢所有iSCSI目標時，IPS模組僅返回該iSCSI主機根據訪問控制策略被允許訪問的iSCSI目標清單。
iSCSI會話建立：當IP主機發起iSCSI會話時，IPS模組驗證指定的iSCSI目標（在會話登入請求中）是否為靜態對映目標，如果為true，則驗證是否允許IP主機的iSCSI節點名稱訪問目標。如果IP主機沒有存取許可權，則其登入會遭到拒絕。

然後，IPS模組建立此IP主機的FC虛擬N埠（N埠可能已經存在），並執行FC名稱伺服器查詢，以獲取IP主機訪問的FC目標pWWN的FCID。它使用IP主機虛擬N埠的pWWN作為名稱伺服器查詢的請求者。因此，名稱伺服器對pWWN執行區域強制查詢並響應查詢。如果名稱伺服器返回FCID，則接受iSCSI會話。否則，登入請求將被拒絕。
