Additional Raid Disk Drives Configuration - Intergraph InterServe 9000 System Reference Manual

Additional RAID Disk Drives Configuration

The Mylex RAID controller BIOS manages up to eight disk drives. If a system has more
than eight drives configured across multiple RAID controllers, you must ensure that the
RAID disk drive containing the operating system (boot drive) is recognized during the BIOS
scan sequence. The BIOS scan sequence starts with the internal devices and then moves to
the PCI slots in the following order: A1, A2, A3, B1, B2, B3, B4. The operating system
boot device must be attached to the RAID controller that is seen first during the scan of the
PCI slots. See the System Reference for more information.
If your system was shipped with more than three RAID drives, then the extra drives are not
configured. Before you can use them, the additional RAID drives must be configured into
one or more arrays using the Mylex RAID controller BIOS or the Mylex RAID configuration
utility. The following steps provide the general guidelines; see the Mylex documentation for
detailed instructions.
To configure additional drives:
1. Reboot the system.
2. When prompted, press
Menu displays.
3. Select the RAID controller to which the unconfigured RAID drives are connected.
4. From the Main Menu, select View/Update Configuration, then use this option to make
additions to the configuration. This allows you to retain the existing configuration and
create new drive groups. See the Mylex documentation for details.
5. Select the unconfigured RAID drives (shown as RDY) and configure them into one or
more arrays as desired.
CAUTION Do not place different size drives into the same array. If you do, the size of the larger drives
will be truncated to that of the smaller drives, and the remainder will be unusable.
6. When the configuration has been applied, set the drive options to your desired settings.
7. Once all of the RAID drives are defined, press
the configuration.
8. From the Main Menu, select Initialize System Drive. Follow the instructions in the
Mylex documentation to mark a system drive and then intialize the drive.
Preparation of the array is complete at this point. You can exit the Mylex RAID
configuration utility and reboot the system. The new RAID pack appears as unpartitioned
disk space under the Disk Administrator utility. You must partition and format the disk
drive space.
