A moreserious,butfarless common problem is an Incomplete Array. An incomplete array results from a
physical drive that fails or becomes missing during:
• RAID level migration
• Disk array transport

Transport is the action of moving the physical drives of a disk array:
• To different slots in the same enclosure
• From one enclosure to another
Ifaphysicaldrivefailsduringatransport,oryoudonotmoveallofthephysicaldrivestotheirnewlocations,
