Necessity of configuring RAID arrays for a RAID controller card
If the LSISAS1078, LSISAS2208, or LSISAS3108 RAID controller card is used, the disks can be recognized by the system only when they are in RAID arrays. If the LSISAS1068, LSISAS2308, or LSISAS3008 RAID controller card is used, the disks can be used as individual disks for OS installation, if they are not in RAID arrays.
