HH024 - Details

• The SAP error message HH024, which states "At least 1 mirror chunk is offline," typically relates to issues with the database storage configuration, particularly in environments using high availability or mirroring setups. This error indicates that one or more of the mirrored data chunks (or segments) in the database are not accessible or are offline, which can lead to potential data loss or unavailability of the database.
  Causes:
  
  Hardware Failure: A physical disk failure or issues with the storage subsystem can cause one or more mirror chunks to go offline.
  Network Issues: If the mirrored database is on a different server, network connectivity issues can prevent access to the mirror.
  Configuration Errors: Incorrect configuration settings in the database or storage system can lead to chunks being marked as offline.
  Database Corruption: Corruption in the database can cause certain chunks to become unavailable.
  Maintenance Activities: Scheduled maintenance or updates might inadvertently take a chunk offline.
