Recovery Utilities (1) Reset Backup and Restore Fail Recovery starts depending on the ETERNUS DX system status

• Status "Backup Fail" occurs on an ETERNUS DX system that cannot start up because an error occurred during a power failure or while turning off

• Status "Restore Fail" occurs on an ETERNUS DX system that cannot start up because an error occurred while turning power on
