Ejemplo de Configuración de Linux iSCSI Host to 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 comandos SCSI, los encapsulan en paquetes IP y los redirigen al Cisco SN 5420, Cisco SN 5428, Cisco SN 5428-2 o Cisco MDS/IPS-8. Este documento proporciona configuraciones de ejemplo para el host iSCSI Linux a MDS/IPS-8.Antes de comenzar

La información que se presenta en este documento se originó a partir de dispositivos dentro de un ambiente de laboratorio específico. All of the devices used in this document started with a cleared (default) configuration. Si la red está funcionando, asegúrese de haber comprendido el impacto que puede tener un comando antes de ejecutarlo.
Teoría Precedente
El módulo IPS proporciona a los hosts IP acceso a los dispositivos de almacenamiento 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 la forma de interfaces Gigabit Ethernet que se configuran 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 debe tener instalado un controlador iSCSI compatible. Mediante el protocolo iSCSI, el controlador iSCSI permite que un host iSCSI transporte 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 viceversa). 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. En esta configuración verá un ejemplo de asignación estática. 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 configuración de mapping/enmascaramiento de LUNs basada en los pWWNs y/o nWWNs del iniciador.
Puede controlar el acceso a cada destino iSCSI asignado estáticamente especificando una lista de puertos IPS en los que se anunciará y especificando una lista de nombres de nodos iniciadores iSCSI a los que se permitirá acceder. 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 ha permitido 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 el host IP está accediendo. 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.

| En el host Linux, se debe modificar iscsi.conf. [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=
!--- The iSCSI driver discovery daemon process looks up each discovered target !--- in the /var/lib/iscsi/bindings file. If an entry exists in the file for the !--- target, the corresponding SCSI target ID is assigned to the target. If !--- no entry exists for the target, the smallest available SCSI target ID !--- is assigned and an entry is written to the /var/lib/iscsi/bindings file for !--- this target. !--- Note that the /var/lib/iscsi/bindings file will permanently contain entries !--- for all iSCSI targets ever logged into from this host. If a target is !--- no longer available to a host, you can manually edit the file and remove !--- entries so that the obsolete target no longer consumes a SCSI target ID. !--- If you know the iSCSI target name of a target in advance, and you want !--- it to be assigned a particular SCSI target ID, you can add an entry !--- manually. You should stop the iSCSI driver before editing the !--- /var/lib/iscsi/bindings file. !--- To manually start the iSCSI driver, enter /etc/init.d/iscsi start !--- To manually stop the iSCSI driver, enter /etc/init.d/iscsi stop |
