    Did you add HDD's without rebooting the server? If so, what mechanism are you using to recognize that drives have been added?

    Most SLES's have a script called that will query the bus and update the kernel. Check for the script - read up on it - install it if you don't have it. Plenty of information is available via Google.

    Once the kernel is updated, you will see the drive listed in /proc/scsi/scsi and you can use fdisk/YaST to partition them.

    cat /proc/scsi/scsi

    RAID is a actually several ways to make Drives more failure resistant. Here is a quick overview.

    RAID - Wikipedia, the free encyclopedia

    The number of disks used depends on the scheme used. (see above link)

    RAID is only useful if you are trying for 5 9s uptime ie 99.999%

    Most desktops do not require that level of reliability. If you want to use all your disks for storage ie 4x750GB or 3 TB then you must completely redo your system. Backup data. Turn off RAID in the BIOS reformat everything set up new partitions reinstall restore backed up data.

    You have some Adaptec RAID card. If the SCSI card isn't passing the disks to the OS, you need to read the manual for your Adaptec card to configure the drives and *how* the card should pass them to the OS.

    Depending on the SCSI card, you may enter a "configuration" utility while booting, or have to run a config utility from floppy/USB/CD.
