Не отображаются все диски на Solaris 10, использующем двухканальный RAID-контроллер Dell Perc5i

У меня есть Dell PowerEdge 2950 под управлением Solaris 10 с 8 дисками. Я хочу поменять некоторые диски на новые. Моя проблема на данный момент заключается в том, что я вижу только половину из них, и, похоже, нет никаких признаков других 4.
