Questo capitolo descrive l'installazione e la configurazione specifiche del sistema SAP HANA BM1 utilizzato per la documentazione di questa soluzione. Il sistema HANA QM1 è stato implementato allo stesso modo.
Ulteriori informazioni generiche sull'implementazione e le best practice sono disponibili "SAP HANA su sistemi NetApp ASA con protocollo Fibre Channel".
Configurazione dello storage
Le seguenti screenshot mostrano la creazione della storage unit BM1_data_mnt00001. Le storage unit per HANA log e shared sono state create allo stesso modo.
Il WWPN degli adattatori FCP dell'host HANA può essere elencato con il comando sanlun, che fa parte delle utilità host NetApp come descritto nel capitolo "Configurazione host HANA".
sapcc-hana-tst-02:~ # sanlun fcp show adapter host20 WWPN:100070b7e40bbadb host21 WWPN:100070b7e40bbadc
Fai clic su "aggiungi" per creare l'unità di archiviazione.
Lo screenshot mostra le tre storage unit create per il sistema HANA BM1.
Configurazione host HANA
Prima di configurare l'host, è necessario scaricare le utilità host SAN NetApp dal sito "Supporto NetApp" e installarle sui server HANA. La documentazione delle utilità host include informazioni sul software aggiuntivo che devi installare a seconda dell'HBA FCP utilizzato.
Le NetApp SAN host utilities possono essere utilizzate anche per ottenere il WWPN degli adattatori host necessari per configurare la mappatura host sul sistema storage.
sapcc-hana-tst-02:~ # sanlun fcp show adapter host20 WWPN:100070b7e40bbadb host21 WWPN:100070b7e40bbadc
Configurazione multipath
-
Esegui il comando Linux rescan-scsi-bus.sh -a su ogni server per rilevare nuove LUN.
-
Esegui il comando sanlun lun show e verifica che tutti i LUN richiesti siano visibili. L'output mostra i LUN e i relativi file di dispositivo che hanno quattro percorsi FC dall'host ai controller di storage.

Con la configurazione descritta, la directory /usr/sap/BM1 verrà memorizzata sul disco del sistema operativo. Se /usr/sap/BM1 deve essere memorizzata su un disco separato, è necessario configurare un LUN aggiuntivo sul sistema storage. |
