To reuse a consistent copy of the SAP HANA persistence in another SAP HANA installation, consider the following:
For more information, see the SAP HANA Administration Guide.
These use cases do not include the replication of aan SAP HANA shared file system, which includes the binary files and configuration files. Both sites must have access to the same NFS share with the SAP HANA shared file system, or SAP HANA must be installed at the DR site on a local NFS share. The SAP HANA installation at the DR site must be identical to the installation at the production site in number of workers, standby nodes, RAM sizes, and SAP HANA SID.
Note: If you use a shared block file system (OCFS2, GFS2) for the SAP HANA shared file system, you can also use the PowerMax SRDF for those devices. If the SAP HANA shared file system is provided by eNAS, the VDM synchronous replication feature provides the ability to manually fail over a VDM from a local eNAS system to a remote eNAS system using block-level SRDF, but only with synchronous replication (SRDF/S). These scenarios are outside the scope of this guide.
