HANA File System Layout



The SAP HANA database lifecycle manager (HDBLCM) requires certain file systems in order to successfully install an SAP HANA system.
The file systems can be defined manually before installation and then specified during installation, or the default file systems can be used. It is important that the file systems listed below are available and have the recommended disk space before starting the SAP HANA database lifecycle manager.
Default File Systems:

Installation path (sapmnt)

/hana/shared/

The mount directory is used for shared files between all hosts in an SAP HANAsystem. This directory needs to be accessible to each of the servers in the SAP HANA cluster.

Subdirectories:

/hana/shared/<SID> - Contains executable programs (exe), globally shared data (global), instance profiles (profile), and SAP HANAconfiguration files.

/hana/shared/<SID>/hdbclient - The SAP HANA client installation path.

The following paths apply when the SAP HANA studio is installed:

/hana/shared/<SID>/hdbstudio_update - The studio repository installation path. The studio repository is used to update the local SAP HANAstudio installation.

/hana/shared/<SID>/hdbstudio - The SAP HANA studio installation path.

System instance

/usr/sap

This is the path to the local SAP system instance directories. It is possible to join this location with the Linux installation.

Subdirectories:

/usr/sap/hostctrl - The SAP host agent directory.

/usr/sap/<SID> - Contains symbolic links to system executables (SYS) and the home directory (home) of the <sid>adm user.

Data volume

/hana/data/<SID>

The default path to the data directory depends on the system ID of the SAP HANAhost.

Log volume

/hana/log/<SID>

The default path to the log directory depends on the system ID of the SAP HANAhost.


The file systems /hana/data/<SID> and /hana/log/<SID> may use shared file systems like NFS, or block storage using the SAP HANA storage connector API with non shared file systems.
The installation path (/hana/shared) is visible on all hosts, and by default, is also used for backup. However, backup directories must belong to a shared file system, and be configured manually.
