Esempio di configurazione da host iSCSI HP-UX a MDS/IPS-8
Sommario
Introduzione
I driver iSCSI Cisco, che risiedono sul server, sono un componente chiave di una soluzione iSCSI. Questi driver iSCSI intercettano i comandi SCSI (Small Computer System Interface), li incapsulano in pacchetti IP e li reindirizzano al documento Cisco SN 5420, Cisco SN 5428, Cisco SN 5428-2 o Cisco MDS/IPS-8.This per fornire configurazioni di esempio per l'host iSCSI HP-UX al documento SN 5428.
Prerequisiti
Requisiti
Prima di provare la configurazione, verificare che siano soddisfatti i seguenti requisiti:
-
Installare il driver iSCSI compatibile con la versione HP-UX in uso. La versione più aggiornata del driver è disponibile nella pagina di download Cisco iSCSI Driver (solo utenti registrati) all'indirizzo Cisco.com. Il file README.txt è incluso nel file zip(tar) del driver. Il file README contiene informazioni sul contratto di licenza, istruzioni per l'installazione e la configurazione dei driver e una panoramica tecnica dell'architettura dei driver.
-
I requisiti del sistema operativo e i requisiti delle patch sono descritti nella sezione Requisiti di sistema delle note di rilascio del driver iSCSI Cisco per HP-UX.

(solo utenti Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi.
Convenzioni
Il Cisco MDS 9000 utilizzato in questo documento si riferisce a qualsiasi prodotto switch Fibre Channel (FC) della famiglia MDS 9000 (MDS 9506, MDS 9509, MDS 9216). Il blade Cisco Intrusion Prevention System (IPS) fa riferimento al modulo IP Storage Services. Per ulteriori informazioni sulle convenzioni usate, consultare il documento Cisco sulle convenzioni nei suggerimenti tecnici.
Premesse
Il modulo Cisco Intrusion Prevention System (IPS) fornisce agli host IP l'accesso ai dispositivi di storage Fibre Channel (FC). Il modulo IPS è DS-X9308-SMIP. Fornisce routing SCSI trasparente. Gli host IP che utilizzano il protocollo iSCSI possono accedere in modo trasparente alle destinazioni iSCSI sulla rete FC. L'host IP invia i comandi SCSI incapsulati nelle unità dati del protocollo (PDU) iSCSI a una porta IPS MDS 9000 su una connessione TCP/IP. Sul modulo IPS, la connettività viene fornita sotto forma di interfacce GE configurate in modo appropriato. Il modulo IPS consente di creare destinazioni iSCSI virtuali e di mapparle alle destinazioni FC fisiche disponibili nella SAN FC. Presenta le destinazioni FC agli host IP come se le destinazioni fisiche fossero collegate alla rete IP.
Ogni host iSCSI che richiede l'accesso allo storage tramite il modulo IPS deve disporre di un driver iSCSI compatibile installato. Con l'aiuto del protocollo iSCSI, il driver iSCSI consente a un host iSCSI di trasportare le richieste e le risposte SCSI su una rete IP. Dal punto di vista di un sistema operativo host, il driver iSCSI sembra essere un driver di trasporto SCSI simile a un driver FC per un canale periferica nell'host. Dal punto di vista del dispositivo di storage, ogni host IP viene visualizzato come host FC. Il routing di SCSI dall'host IP al dispositivo di storage FC è costituito dalle seguenti azioni principali:
-
Trasporto di richieste e risposte iSCSI su una rete IP tra gli host e il modulo IPS
-
Instradamento delle richieste e delle risposte SCSI tra gli host di una rete IP e il dispositivo di storage FC (conversione da iSCSI a FCP e da FCP a iSCSI). Questo routing viene eseguito dal modulo IPS.
-
Trasporto di richieste o risposte FCP tra il modulo IPS e i dispositivi di storage FC
Per impostazione predefinita, il modulo IPS non importa destinazioni FC in iSCSI. È necessario configurare il mapping dinamico o statico prima che il modulo IPS renda disponibili le destinazioni FC agli iniziatori iSCSI. Quando entrambi sono configurati, le destinazioni FC mappate staticamente hanno un nome configurato. Questo documento fornisce un esempio di mappatura statica. Con la mappatura dinamica, ogni volta che l'host iSCSI si connette al modulo IPS, viene creata una nuova porta FC N e gli nWWN e i pWWN allocati per questa porta N possono essere diversi. Utilizzare il metodo di mappatura statica se è necessario ottenere gli stessi nWWN e pWWN per l'host iSCSI ogni volta che si connette al modulo IPS. La mappatura statica può essere utilizzata sul modulo IPS per accedere ad array di storage FC intelligenti che dispongono di configurazioni di mappatura e masking dei numeri di unità logica (LUN, Logical Unit Number) e di controllo dell'accesso basate sui pWWN o nWWN dell'iniziatore.
È possibile controllare l'accesso a ogni destinazione iSCSI mappata staticamente creando un elenco specifico di porte IPS su cui la destinazione viene annunciata e creando un elenco di nomi di nodi iniziatore iSCSI autorizzati ad accedervi. Il controllo degli accessi basato sullo zoning FC e il controllo degli accessi basato su iSCSI sono i due meccanismi attraverso i quali è possibile fornire il controllo degli accessi per iSCSI. Entrambi i metodi possono essere utilizzati contemporaneamente. In questa configurazione lo zoning predefinito è consentito per VSAN specifiche. I moduli IPS utilizzano elenchi di controllo degli accessi basati su nomi di nodi iSCSI e su zoning FC per imporre il controllo degli accessi durante il rilevamento iSCSI e la creazione di sessioni iSCSI.
-
Individuazione iSCSI: Quando un host iSCSI crea una sessione di rilevamento iSCSI e esegue query per tutte le destinazioni iSCSI, il modulo IPS restituisce solo l'elenco di destinazioni iSCSI a cui l'host iSCSI è autorizzato ad accedere in base ai criteri di controllo di accesso.
-
Creazione di sessioni iSCSI: Quando un host IP avvia una sessione iSCSI, il modulo IPS verifica se la destinazione iSCSI specificata (nella richiesta di accesso alla sessione) è una destinazione mappata statica e, se true, verifica se il nome del nodo iSCSI dell'host IP è autorizzato ad accedere alla destinazione. Se l'host IP non ha accesso, il relativo accesso viene rifiutato.
Il modulo IPS crea quindi una porta FC virtuale N (la porta N potrebbe già esistere) per questo host IP ed esegue una query sul server dei nomi FC per il FCID del nome WWN della destinazione FC a cui l'host IP accede. Viene utilizzato il nome WWN della porta N virtuale dell'host IP come richiedente della query del server dei nomi. Pertanto, il server dei nomi esegue una query applicata a livello di zona per pWWN e risponde alla query. Se l'FCID viene restituito dal server dei nomi, la sessione iSCSI viene accettata. In caso contrario, la richiesta di accesso viene rifiutata.
