本章介绍用于本解决方案文档的 SAP HANA 系统 BM1 的具体安装和配置。HANA 系统 QM1 的部署方式相同。
可以找到其他通用部署信息和最佳实践 "基于采用光纤通道协议的 NetApp ASA 系统的 SAP HANA"。
存储配置
以下屏幕截图显示了存储单元 BM1_data_mnt00001 的创建。HANA 日志和共享的存储单元以相同的方式创建。
HANA 主机 FCP 适配器的 WWPN 可以使用 sanlun 命令列出，该命令是 NetApp 主机实用程序的一部分，如第 "HANA 主机配置" 章所述。
sapcc-hana-tst-02:~ # sanlun fcp show adapter host20 WWPN:100070b7e40bbadb host21 WWPN:100070b7e40bbadc
单击添加以创建存储单元。
屏幕截图显示了为 HANA 系统 BM1 创建的三个存储单元。
HANA 主机配置
在设置主机之前，必须从 "NetApp 支持"站点下载 NetApp SAN 主机实用程序并安装在 HANA 服务器上。主机实用程序文档包括有关必须安装的其他软件的信息，具体取决于所使用的 FCP HBA。
还可以使用 NetApp SAN 主机实用程序获取在存储系统上配置主机映射所需的主机适配器的 WWPN。
sapcc-hana-tst-02:~ # sanlun fcp show adapter host20 WWPN:100070b7e40bbadb host21 WWPN:100070b7e40bbadc
多路径配置
-
在每台服务器上运行 Linux rescan-scsi-bus.sh -a 命令以发现新的 LUN。
-
运行 sanlun lun show 命令，验证所有必需的 LUN 都可见。输出显示 LUN 和相应的设备文件具有从主机到存储控制器的四个 FC 路径。
sapcc-hana-tst-02:~ # sanlun lun show | grep BM1 a30-hana-primary BM1_shared_1 /dev/sdx host21 FCP 250g cDOT a30-hana-primary BM1_log_mnt00001_1 /dev/sdw host21 FCP 250g cDOT a30-hana-primary BM1_data_mnt00001_1 /dev/sdv host21 FCP 250g cDOT a30-hana-primary BM1_shared_1 /dev/sdu host21 FCP 250g cDOT a30-hana-primary BM1_log_mnt00001_1 /dev/sdt host21 FCP 250g cDOT a30-hana-primary BM1_data_mnt00001_1 /dev/sds host21 FCP 250g cDOT a30-hana-primary BM1_shared_1 /dev/sdh host20 FCP 250g cDOT a30-hana-primary BM1_log_mnt00001_1 /dev/sdg host20 FCP 250g cDOT a30-hana-primary BM1_shared_1 /dev/sdk host20 FCP 250g cDOT a30-hana-primary BM1_data_mnt00001_1 /dev/sdl host20 FCP 250g cDOT a30-hana-primary BM1_log_mnt00001_1 /dev/sdi host20 FCP 250g cDOT a30-hana-primary BM1_data_mnt00001_1 /dev/sdj host20 FCP 250g cDOT sapcc-hana-tst-02:~ #

运行 multipath -r 和 multipath -ll 命令以获取设备文件名的全球标识符 (WWID)。

编辑 /etc/multipath.conf 文件并添加 WWID 和别名。
sapcc-hana-tst-02:~ # cat /etc/multipath.conf
multipaths {
multipath {
wwid 3600a098038323537342b596e55666737
alias a30-hana-primary-BM1-data-mnt00001
}
multipath {
wwid 3600a098038323537342b596e55666738
alias a30-hana-primary-BM1-log-mnt00001

multipath {
wwid 3600a0980383235324a245a4749384947
alias a30-hana-primary-BM1-shared
}
}
-
运行 multipath -r 命令重新加载设备映射。
-
运行 multipath -ll 命令以列出所有 LUN、别名和存储路径，从而验证配置。

使用所述配置，/usr/sap/BM1 目录将存储在操作系统磁盘上。如果 /usr/sap/BM1 应存储在单独的磁盘上，则必须在存储系统上配置其他 LUN。 |
