Open a terminal (SSH or local to the system) and ensure the prompt is logged in as a user who has read, write, and execute permissions on the SAP HANA data persistence mount point. The data persistence mount point can be identified by inspecting the global.ini persistence section for “basepath_datavolumes”. Take the value offered by the global.ini file and remove the database name from the path to only get the base path mount point (this assumes that the SAP HANA systems have been set up with a mount point and single volume each for log and data). We will then use the “fsfreeze” Linux utility to resume IO to the volume and allow the database to continue operation.
