本章詳細介紹用於此解決方案文件的 SAP HANA 系統 BM1 的具體安裝和組態。HANA 系統 QM1 的部署方式相同。
更多通用部署資訊和最佳實務請參閱此處 "採用ASA Fibre Channel Protocol的NetApp解決方案上的SAP HANA"。
儲存組態
以下快照顯示儲存單元 BM1_data_mnt00001 的建立過程。HANA 日誌和共享的儲存單元已以相同方式建立。
可以使用 sanlun 命令列出 HANA 主機 FCP 介面卡的 WWPN，該命令是 NetApp 主機公用程式的一部分，如第 "HANA 主機組態" 章所述。
sapcc-hana-tst-02:~ # sanlun fcp show adapter host20 WWPN:100070b7e40bbadb host21 WWPN:100070b7e40bbadc
點選「新增」建立儲存設備單元。
快照顯示為 HANA 系統 BM1 建立的三個儲存設備單元。
HANA 主機組態
在設定主機之前，必須先從 "NetApp支援"站台下載 NetApp SAN 主機公用程式，並將其安裝在 HANA 伺服器上。主機公用程式文件包含有關必須根據所使用的 FCP HBA 安裝之其他軟體的資訊。
NetApp SAN 主機公用程式也可用於取得在儲存系統上設定主機對映所需的主機介面卡的 WWPN。
sapcc-hana-tst-02:~ # sanlun fcp show adapter host20 WWPN:100070b7e40bbadb host21 WWPN:100070b7e40bbadc
多重路徑組態
-
在每台伺服器上執行 Linux rescan-scsi-bus.sh -a 命令以探索新的 LUN。
-
執行 sanlun lun show 命令並驗證所有必要的 LUN 是否可見。輸出結果顯示 LUN 及其對應的裝置檔案有四條從主機到儲存控制器的 FC 路徑。
