Les informations présentées dans ce document ont été créées à partir de périphériques dans un environnement de laboratoire spécifique. All of the devices used in this document started with a cleared (default) configuration. Si vous travaillez dans un réseau opérationnel, assurez-vous de bien comprendre l'impact potentiel de toute commande avant de l'utiliser.
Le module IPS fournit aux hôtes IP un accès aux périphériques de stockage FC. Le module IPS est DS-X9308-SMIP. Il fournit un routage SCSI transparent. Les hôtes IP utilisant le protocole iSCSI peuvent accéder de manière transparente aux cibles iSCSI sur le réseau FC. L’hôte IP envoie des commandes SCSI encapsulées dans des unités de données de protocole (PDU) iSCSI à un port IPS MDS 9000 via une connexion TCP/IP. Sur le module IPS, la connectivité est fournie sous la forme d'interfaces Gigabit Ethernet configurées de manière appropriée. Le module IPS vous permet de créer des cibles iSCSI virtuelles et de les mapper à des cibles FC physiques disponibles dans le SAN FC. Il présente les cibles FC aux hôtes IP comme si les cibles physiques étaient connectées au réseau IP.
Chaque hôte iSCSI nécessitant un accès au stockage via le module IPS doit disposer d'un pilote iSCSI compatible. Grâce au protocole iSCSI, le pilote iSCSI permet à un hôte iSCSI de transporter des requêtes et des réponses SCSI sur un réseau IP. Du point de vue d'un système d'exploitation hôte, le pilote iSCSI semble être un pilote de transport SCSI similaire à un pilote FC pour un canal périphérique dans l'hôte. Du point de vue du périphérique de stockage, chaque hôte IP apparaît comme un hôte FC.
Le routage SCSI de l'hôte IP vers le périphérique de stockage FC se compose des actions principales suivantes :
Par défaut, le module IPS n'importe pas de cibles FC vers iSCSI. Le mappage dynamique ou statique doit être configuré avant que le module IPS ne mette les cibles FC à la disposition des initiateurs iSCSI. Lorsque les deux sont configurées, les cibles FC mappées de manière statique ont un nom configuré. Dans cette configuration, vous verrez un exemple de mappage statique. Avec le mappage dynamique, chaque fois que l'hôte iSCSI se connecte au module IPS, un nouveau port FC N est créé et les nWWN et pWWN attribués à ce port N peuvent être différents. Utilisez la méthode de mappage statique si vous devez obtenir les mêmes nWWN et pWWN pour l'hôte iSCSI chaque fois qu'il se connecte au module IPS. Le mappage statique peut être utilisé sur le module IPS pour accéder aux baies de stockage FC intelligentes qui ont un contrôle d'accès et une configuration de mappage/masquage de LUN basée sur les noms de domaine (pWWN) et/ou nWWN de l'initiateur.
Vous pouvez contrôler l'accès à chaque cible iSCSI mappée de manière statique en spécifiant une liste de ports IPS sur lesquels elle sera annoncée et en spécifiant une liste des noms de noeuds initiateurs iSCSI autorisés à y accéder. Le contrôle d'accès basé sur le zonage FC et le contrôle d'accès basé sur iSCSI sont les deux mécanismes par lesquels le contrôle d'accès peut être fourni pour iSCSI. Les deux méthodes peuvent être utilisées simultanément. Dans cette configuration, le zonage par défaut a été autorisé pour un VSAN spécifique. Les modules IPS utilisent à la fois des listes de contrôle d'accès basées sur le nom de noeud iSCSI et sur le zonage FC pour appliquer le contrôle d'accès lors de la découverte iSCSI et de la création de sessions iSCSI.
Le module IPS crée ensuite un port N virtuel FC (le port N peut déjà exister) pour cet hôte IP et effectue une requête de serveur de noms FC pour le FCID du pWWN cible FC auquel l'hôte IP accède. Il utilise le pWWN du port N virtuel de l'hôte IP comme demandeur de la requête de serveur de noms. Ainsi, le serveur de noms effectue une requête appliquée à la zone pour le nom de domaine virtuel (pWWN) et répond à la requête. Si le FCID est renvoyé par le serveur de noms, la session iSCSI est acceptée. Sinon, la demande de connexion est rejetée.

Sur l'hôte Linux, iscsi.conf doit être modifié. [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 |
