• F - faulty - unit can be turned off from array
• R - hot remove - unit can be removed from array without shutting down the system.
• ST - describes state of unit in array, which can be:
• A - This means that Unit is active in array
• * - Number of Unit that belongs to the array
• S - Spare or spare rebuilding - this means that unit is free and can be added to the array or is
