According the bit position: 0 Data lost: Within the logical unit data has been lost. 1 Dynamic reconfiguration in progress: The logical unit is being reconfigured. In this state all data is still protected. 2 Exposed: Within the logical unit data is not protected. In this state all data is still valid, however, loss of data/data-availability is unavoidable in the event of a failure. 3 Fractionally exposed: Within the logical unit part of the data is not protected. In this state all data is still valid, however, a failure may cause a loss of data or a loss of data availability. 4 Partially exposed: Within the logical unit one or more underlying storage devices have failed. In this state all data is still protected. 5 Protected rebuild: The logical unit is in the process of a rebuild operation. In this state all data is protected. 6 Protection disabled: Within the logical unit the data protection method has been disabled. In this state all data is still valid, however, however, loss of data/data-availability is unavoidable in the event of a failure. 7 Rebuild: The data protection method is in the process of rebuilding data. In this state data is not protected. 8 Recalculate: The logical unit is in the process of a recalculate operation. 9 Spare in use: Within the logical unit a storage device in full or part being used to store data.
