What is a common reason for receiving the Disk Full (Alert 30) alert in SAP HANA systems?

The alert regarding Disk Full (Alert 30) in SAP HANA systems commonly occurs due to running out of free space on the /hana/shared volume. This volume is crucial as it is where the database files are stored, including data and logs. When this volume reaches its capacity limit, the system is unable to write any new data or logs, leading to the Disk Full alert.

This situation can arise from several factors such as excessive data growth, insufficient disk space provisioning during the initial setup, or large transactions that require more immediate storage capacity. Recognizing this alert and addressing the underlying issue—either by freeing up space, archiving old data, or increasing disk capacity—is essential for ensuring the continued smooth operation of the database.

Other options, while they may indicate issues within the SAP HANA environment, do not directly lead to the Disk Full alert. For instance, data corruption could cause a range of operational problems but would not specifically trigger a Disk Full alert. Similarly, high CPU usage could affect the system's performance but would not be related to disk space issues. Network latency, on the other hand, deals with communication delays and does not impact the available disk space directly.
