The configuration example in this guide assumes that the following basic installation and configuration operations are complete on the SAP HANA nodes:
Note: SAP HANA can only be installed on certified server hardware. A certified SAP HANA expert must perform the installation.
For both Red Hat Enterprise Linux and SUSE, the native MPIO already contains default configuration parameters for PowerMAX arrays to provide optimal performance in most environments. You do not have to create a device stanza for these arrays unless you want to modify the default behavior. The /etc/multipath.conf file is installed by default when you install the device-mapper-multipath package.
Note: For the latest information about the operating system version and storage array MPIO settings for native multipathing, always refer to the Dell EMC Host Connectivity Guide for Linux.
The SAP HANA persistence must be visible to every node in the SAP HANA cluster. Run the rescan-scsi-bus.sh command or reboot each node, as described in this section.
To verify that the volumes are visible:
multipath -ll | grep -B1 -A5 512G
Figure 2. List data volumes command
multipath -ll | grep -B1 -A5 256G
Figure 3. List log volumes command
The unique device identifier of the multipath device must match the WWN of the volumes that you created in the Unisphere UI. (When viewed on a Linux host, the WWN of the volume from the PowerMax array is now preceded by a 3.)
mkfs.xfs /dev/mapper/360000970000197900137533030303234
After all the file systems are created, you are ready to install the SAP HANA scale-out cluster.
