We used the Unisphere for PowerMax UI to configure all storage devices, storage groups, port groups, host groups, and the masking view for the SAP HANA scale-out cluster.
To create a parent storage group and volumes:
The following figure shows the Unisphere for PowerMax UI:

Figure 7. Storage Groups page
Figure 8. Provision Storage page
For our 3+1 SAP HANA cluster, we needed three data volumes of 512 GB capacity each and three log volumes of 256 GB capacity each:
The new cascaded storage group is created.
Figure 9. HANA_DATA storage groups
The Volumes page is displayed, as shown in the following figure:
Figure 10. Volumes page
You might have to scroll to find the WWN of the volume.
The SAP HANA storage connector fcClient uses the WWN specified in the SAP HANA global.ini file to identify a storage LUN.
To create a host group:
The following page appears:
Figure 11. Create Host page
The new host is created.
Figure 12. Create Host Group page
The new host group is created.
To create a port group:
Figure 13. Creating a port group
Note: For a single host, we recommend a 1:1 relationship between a host HBA and a storage front-end port. Because we created a port group for an SAP HANA cluster, we required throughput and bandwidth for multiple hosts.
To create and configure a storage group:
The following page is displayed:
Figure 14. Storage Group page
A PowerMax masking view combines the storage group, port group, and host group, and enables access from the SAP HANA nodes to the storage volumes.
Follow these steps to create a masking view:
Figure 1. Create Masking View page
The masking view is created. The SAP HANA nodes now have access to the storage volumes.
We created an SAP HANA scale-out system with three worker nodes and one standby node (3+1). In an SAP HANA cluster with four nodes, each node must have access to every SAP HANA device. During SAP HANA startup, the SAP HANA nameserver along with the SAP HANA storage connector fcClient mounts the volumes to the correct SAP HANA node and I/O fencing.
Ensure that you correctly prepare the SAP HANA nodes and the SAP HANA global.ini file, as described in subsequent sections, before you perform the SAP HANA installation.
Note: When using fcClient, do not auto-mount the device using /etc/fstab.
