Scenarios

• Data on a hard drive will be deleted after the hard drive is added to a RAID array. Before creating a RAID array, check that there is no data on hard drives or the data on hard drives is not required. If the hard disk data needs to be retained, back up the data first.
• The LSI SAS2308 supports SAS/SATA HDDs and SSDs. Hard drives in one RAID array must be of the same type, but can have different capacities or be provided by different vendors.
• RAID 0, 1, 10, and 1E lists the number of hard drives required by each RAID level.

      Table 5-13 Parameter description

      Parameter	Description
      Selected RAID Level	Indicates the selected RAID level.
      Select Interface Type	Selects an interface type. If the controller card controls hard drives of different interface types, you can use this parameter to filter the hard drives.
      Select Media Type	Selects a hard drive type. If the controller card controls hard drives of different capacities, you can use this parameter to filter the hard drives.
      0:2:0 SATS HDD-512b 3726 GB	Indicates the selectable hard drives. NOTE: If there are multiple hard drives, multiple hard drive records are displayed.
      Check All	Selects all listed hard drives.
      Uncheck All	Deselects all hard drives.

   2. Select member drives by referring to Table 5-13.
      • A RAID 10 array can contain four, six, eight, or ten hard drives (even numbers).
      • If the total number of hard drives in all RAID arrays under a RAID controller card exceeds 14, no hard drive can be added to RAID arrays.

5. Save the settings.
   1. Use ↑ and ↓ to select Apply Changes and press Enter.
