Currently only one log partition is supported for each service, so the default file names are:

The recommended time to enable data and log volume encryption is immediately after installation or tenant database creation. If you received SAP HANA from a hardware or hosting partner, enable encryption after handover.

To protect data saved to disk from unauthorized access at operating system level, the SAP HANA database supports data encryption in the persistence layer. Data volume encryption protects the data area on disk, while redo log encryption protects the log area on disk.
