use the adaptec raid configuration utility programs and scsiselect utility (also referred to as ibm serveraid-7e) to add raid levels 0 and 1 functionality to the integrated serial ata controller and the integrated scsi controller. be sure to use these programs as described in this document. use these programs to:

    1 configure a redundant array of independent disks (raid) array

    2 view or change your raid configuration and associated devices

    consider the following information when using the adaptec raid configuration utility programs and scsiselect utility program to configure and manage arrays:

    1 the integrated scsi controller with integrated scsi raid (scsi models) and the integrated serial ata controller (sata models) with integrated sata raid supports raid levels 0 and 1 with the option of having a hot-spare drive. installing an optional serveraid controller provides additional raid levels.

    2 hard disk drive capacities affect how you create arrays. drives in an array can have different capacities, but the raid controller treats them as if they all have the capacity of the smallest hard disk drive.

    3 to help ensure signal quality, do not mix drives with different speeds and data rates.

    4 to update the firmware and bios code for an optional serveraid controller, you must use the ibm serveraid support cd that comes with the serveraid option.

    5 if you install a different type of raid controller in your computer, use the configuration method described in the instructions that come with that raid controller to view or change scsi settings for attached devices.
