Ejemplo de Configuración de Host iSCSI HP-UX a MDS/IPS-8
Contenido
Introducción
Los controladores iSCSI de Cisco, que residen en el servidor, son un componente clave de una solución iSCSI. Estos controladores iSCSI interceptan los comandos de interfaz de sistemas informáticos pequeños (SCSI), los encapsulan en paquetes IP y los redirigen al Cisco SN 5420, Cisco SN 5428, Cisco SN 5428-2, o el documento Cisco MDS/IPS-8.This proporciona configuraciones de ejemplo para el host iSCSI HP-UX al SN 5428.
Prerequisites
Requirements
Antes de intentar esta configuración, asegúrese de cumplir estos requisitos:
-
Instale el controlador iSCSI compatible con su versión HP-UX.La versión más actual del controlador se puede encontrar en la página de descarga Cisco iSCSI Driver (sólo clientes registrados) en Cisco.com. El archivo README.txt se incluye en el archivo zip(tar) del controlador. README contiene información sobre el acuerdo de licencia, las instrucciones de instalación y configuración del controlador, y una descripción técnica de la arquitectura del controlador.
-
Los requisitos del sistema operativo y los requisitos de parches se describen en la sección Requisitos del sistema de las Notas de la Versión de Cisco iSCSI Driver para HP-UX.

Convenciones
El Cisco MDS 9000 que se utiliza en este documento se refiere a cualquier producto de switch de canal de fibra (FC) de la familia MDS 9000 (MDS 9506, MDS 9509, MDS 9216). El blade Cisco Intrusion Prevention System (IPS) hace referencia al módulo de servicios de almacenamiento IP. For more information on document conventions, refer to the Cisco Technical Tips Conventions.
Antecedentes
El módulo Cisco Intrusion Prevention System (IPS) proporciona a los hosts IP acceso a dispositivos de almacenamiento Fibre Channel (FC). El módulo IPS es DS-X9308-SMIP. Proporciona routing SCSI transparente. Los hosts IP que utilizan el protocolo iSCSI pueden acceder de forma transparente a los destinos iSCSI en la red FC. El host IP envía comandos SCSI encapsulados en unidades de datos de protocolo (PDU) iSCSI a un puerto IPS MDS 9000 a través de una conexión TCP/IP. En el módulo IPS, la conectividad se proporciona en forma de interfaces GE que están configuradas correctamente. El módulo IPS le permite crear destinos iSCSI virtuales y asignarlos a los objetivos físicos de FC disponibles en la SAN FC. Presenta los destinos FC a los hosts IP como si los destinos físicos se conectaran a la red IP.
Cada host iSCSI que requiera acceso al almacenamiento a través del módulo IPS necesita tener instalado un controlador iSCSI compatible. Con la ayuda del protocolo iSCSI, el controlador iSCSI permite a un host iSCSI transportar solicitudes y respuestas SCSI a través de una red IP. Desde la perspectiva de un sistema operativo host, el controlador iSCSI parece ser un controlador de transporte SCSI similar a un controlador FC para un canal periférico en el host. Desde la perspectiva del dispositivo de almacenamiento, cada host IP aparece como un host FC. El routing SCSI del host IP al dispositivo de almacenamiento FC consta de las siguientes acciones principales:
-
Transporte de solicitudes y respuestas iSCSI a través de una red IP entre hosts y el módulo IPS
-
Enrutamiento de solicitudes SCSI y respuestas entre hosts en una red IP y el dispositivo de almacenamiento FC (conversión de iSCSI a FCP y FCP a iSCSI). Este ruteo lo realiza el módulo IPS.
-
Transporte de solicitudes FCP o respuestas entre el módulo IPS y los dispositivos de almacenamiento FC
El módulo IPS no importa destinos FC a iSCSI de forma predeterminada. La asignación dinámica o estática debe configurarse antes de que el módulo IPS ponga los destinos FC a disposición de los iniciadores iSCSI. Cuando ambos están configurados, los destinos FC asignados estáticamente tienen un nombre configurado. Este documento proporciona un ejemplo de mapeo estático. Con la asignación dinámica, cada vez que el host iSCSI se conecta al módulo IPS, se crea un nuevo puerto FC N y los nWWN y pWWN asignados para este puerto N pueden ser diferentes. Utilice el método de asignación estática si necesita obtener los mismos nWWN y pWWN para el host iSCSI cada vez que se conecte al módulo IPS. El mapping estático se puede utilizar en el módulo IPS para acceder a matrices de almacenamiento de FC inteligentes que tienen control de acceso y configuraciones de asignación de números de unidad lógica (LUN) y enmascaramiento basadas en los pWWN o nWWN del iniciador.
Puede controlar el acceso a cada destino iSCSI asignado estáticamente con la creación de una lista específica de puertos IPS en los que se anuncia el destino y la creación de una lista de nombres de nodos iniciadores iSCSI con permiso para acceder a él. El control de acceso basado en zonas FC y el control de acceso basado en iSCSI son los dos mecanismos mediante los cuales se puede proporcionar el control de acceso para iSCSI. Ambos métodos se pueden utilizar simultáneamente. En esta configuración, se permite la zonificación predeterminada para VSAN específicas. Los módulos IPS utilizan listas de control de acceso basadas en nombres de nodos iSCSI y basadas en zonas FC para aplicar el control de acceso durante la detección de iSCSI y la creación de sesión iSCSI.
-
Detección de iSCSI: Cuando un host iSCSI crea una sesión de detección iSCSI y consultas para todos los destinos iSCSI, el módulo IPS devuelve solamente la lista de destinos iSCSI a los que se permite acceder este host iSCSI en función de las políticas de control de acceso.
-
Creación de sesión iSCSI: Cuando un host IP inicia una sesión iSCSI, el módulo IPS verifica si el destino iSCSI especificado (en la solicitud de inicio de sesión) es un destino asignado estático y, si es true, verifica si el nombre de nodo iSCSI del host IP tiene permiso para acceder al destino. Si el host IP no tiene acceso, se rechaza su inicio de sesión.
El módulo IPS, a continuación, crea un puerto N virtual de FC (es posible que el puerto N ya exista) para este host IP y realiza una consulta de servidor de nombre de FC para el FCID del pWWN de destino de FC al que se accede mediante el host IP. Utiliza el IPWWN del puerto N virtual del host IP como solicitante de la consulta del servidor de nombres. Por lo tanto, el servidor de nombres realiza una consulta por zona para el pWWN y responde a la consulta. Si el servidor de nombres devuelve el FCID, se acepta la sesión iSCSI. De lo contrario, se rechaza la solicitud de inicio de sesión.
