    			  INSTALLATION OF DPT PCI RAID CONFIGURATIONS

    PROBLEM

    During installation of the DPT PCI Disk Array Controller (DAC) in the
    Manhattan P and V Servers, the DAC may not properly configure the drives as a
    RAID configuration.  Problems may also be encountered when mounting Novell
    Netware 4.X volumes after installation of the DAC.

    CAUSE

    The documentation which accompanies the PCI DAC does not make clear the
    importance of following a specific set of steps during the installation of the
    product.  Any deviation from the installation procedure may result in
    complications after the installation.

    Follow the installation procedure below for precise instructions.

    Note: The current DPT Storage Manager diskette part numbers are: 911709-034
    and 911709-035.  For additional information on the DPT PM3224 PCI Storage
    Manager Utilities, see Software Bulletin 0207 on AST's BBS.

    Part I - Configuring the PCI DAC for RAID

    Step 1: Ensure that all SCSI IDs are correctly jumpered either on the drives
    themselves or on the SCSI backplane if one is installed.  Make sure to check
    that the SCSI ID cables fit tightly and are installed over the correct pins.
    At all times during the installation, all drives should be seen by the
    configuration utilities. If any drive is not seen by the utility, check to
    make sure that the SCSI ID is set correctly and that no SCSI IDs are in
    conflict. (For additional information on the Manhattan P And Incorrect SCSI
    ID Assignments, see TB1078 located on AST's BBS.)

    Note: When two drives in the system have the same SCSI ID, the system may
    crash, or drives may intermittently drop on and off-line.  Also note that if a
    SCSI ID jumper is not installed, the default setting is ID 0.  If all drives
    are not recognized, try setting any installed device with ID 0 to another ID
    and re-test the system.

    Step 2: Ensure that termination is installed at the ends of the SCSI bus
    sub-system.  Termination is enabled by default on the PCI DAC.  It is
    recommended that all drives have terminators removed, using the terminators on
    the SCSI backplane for termination.  If a single channel is being used for all
    devices, the CD-ROM should be the last SCSI device on the chain, and
    termination should be enabled on the CD-ROM.

    Step 4: Boot the system and when prompted press  to access System Setup.

    Step 5: Ensure that the video's 640 x 480 refresh rate is set to "60Hz
    Non-interlaced" for standard VGA and SVGA monitors.

    Step 6: Boot the system and when prompted press  to access the DPT
    setup.  The PCI DAC setup screen will appear in approximately one and one
    half minutes after pressing .

    Step 7: Check the settings indicated in the setup program.  The following are
    the recommended settings:

    HBA I/O address:     AUTO
    HBA SCSI ID:         7
    PCI Parity:          Enabled
    SCSI Termination:    Enabled
    SCSI Cmd Queuing:    Enabled
    SCSI TERMPOWER:      Enabled
    PCI Xfers/Burst:     AUTO
    SCSI Xfer Rate:      10MHz
    Extended PCI REQ:    Disabled
    Ext Cable Detection: OFF 10MHz

    Step 8: Boot to a DOS floppy disk and load a mouse driver.

    Step 9: Insert the Storage Manager utility/configuration disk.

    Step 10: Clear all of the drives by typing DPTMGR   /ZAP

    Note: This command clears the area on the drives used by the DPT to save RAID
    configuration information.

    Step 11: Once the "ZAP" has completed, turn the system power OFF and then back
    ON again.

    Step 12: Boot the DOS disk.

    Step 13: Insert the Storage Manager utility/configuration disk.

    Step 14: Run INSTALL.BAT

    Step 15: The screen will blank for about 2 minutes while loading the Storage
    Manager utility/configuration program.

    Step 16: Press  - Continue.

    Step 17: Press  - Continue.

    Step 18: View each device in turn.  Make sure the same make and model hard
    disk drives have the same firmware version and number of blocks.  If the
    firmware versions on identical make and model drives are different, upgrade
    all the drives with a revision of firmware that is recommended for SCSI drives
    used in a hardware RAID environment (or AST qualified firmware revisions for
    AST drives).  If the number of blocks are different, check the number of
    blocks after the drives have been formatted.

    Step 19: View the HBA settings:
    Model: DPT PM3224A/9X
    IRQ: 11 level
    Firmware: 7A0
    Address: FCF0
    Cache:  4MB
    Attached Modules SX4000/1  Raid ready
    1: 4mb ECC SIMM
    SCSI Bus Width:  8bit
    Type: single ended
    Transfer: 10
    SCSI ID: 7
    SCSI buses: 2

    Step 20: Press  - Continue.

    Step 21: Select the OS required.

    Note: Steps for installation of Novell Netware follow.  To install Novell
    Netware, select Netware at this step.

    Step 22: The steps will vary depending upon the chosen operating system.
    Generally, the Storage Manager utility will either create a setup or driver
    diskette for the chosen operating system, or will display information
    pertinent to the particular operating system selected.

    Step 23: When the operation is complete, Storage Manager will issue the
    following message: "Initial System Installation is now complete."

    Step 24: Press  - OK.

    Step 25: The "Storage Manager - Local"  window is displayed.

    Step 26: Select each disk drive in turn and format by pressing  and
    then .

    Step 27: A blue flag indicates that each drive is formatting.

    Step 28: Wait for all drives to finish formatting before continuing.

    Step 29: Press  - Switch view - RAID configuration window.

    Step 30: Press  - Create Array Group. Then  OK to continue.

    Step 31: Select each drive to be included in the array. Press
    to select the drives. A check mark will be displayed on each of the drives to
    be included in the array.

    Step 32: Press  - to include the drives in the array.

    Step 33: Press  - to indicate that drive selection is complete.

    Step 34: Press  and read the screen carefully.

    Note: The logical drive and the array drive will display a black flag to
    indicate that the logical drive's configuration is different from the
    configuration stored on the PCI DAC.  Only when the logical drive is "built"
    and you have exited Storage Manager will the configuration be saved to the PCI
    DAC.

    Step 35: Press  - (File pull down menu).

    Step 36: Press  - to set the configuration. Then  - OK.

    Note: The logical array drive displays blue flag indicating it is "building"
    the array. The individual drive will show a white flag.  Wait until the
    logical drive has finished building - no flags on the drives.

    Step 37: Press  - (File pull down menu).

    Step 38: Press  - to exit the configuration. Then  - OK.

    Step 39: Press  - to save the configuration.

    Step 40: The system will reboot.  Wait until the system finishes rebooting
    before turning the system OFF and ON again.  The system is now ready for the
    OS to be installed.

    Part II - Additional information regarding Novell Netware 4.X

    When installing Novell Netware, follow the documentation included with Netware.
    Ensure that the latest DPT Server Disk Driver is used (PM14NW40.DSK).
    The driver is available from AST's electronic BBS and forums, as well as from
    DPT, as part of the latest storage manager utilities, part numbers 911709-034
    and -035 (file names 709034.EXE and 709035-EXE).

    What follows is a sample step by step approach to installation of Novell
    Netware 4.X.

    Step 1: Boot DOS from a diskette and prepare the hard disks for installation
    of Novell Netware.  Refer to Novell's documentation for specific information.
    Generally, a DOS partition should be created on the hard disk of approximately
    20MB and set active.  Leave the remainder of the drive un-partitioned.
    The DOS partition should then be formatted and DOS should be installed.

    Step 2: SCSI drivers must be loaded in the CONFIG.SYS file and the
    AUTOEXEC.BAT file in order to access the CD-ROM during the Novell Netware 4.X
    installation.  Sample configuration files are:

    CONFIG.SYS
    Device=doscam.sys
    Device=cdrom.sys  /d:phil_001
    Files=12
    Buffers=15

    AUTOEXEC.BAT
    Path=C:\DOS
    MSCDEX   /d:phil_001

    Step 3: Reboot the system to load the SCSI drivers.

    Step 4: Type
    	D:
    to access CD-ROM

    Step 5: Type
    	CD:\NETWARE\ENGLISH

    Step 6: Type
    	INSTALL

    Step 7: Select "Install new netware v4.x"

    Step 8: Select "Retain current disk partitions".

    Step 9: Choose a name for the Server.

    Step 10: Choose an Internal IPX network address.

    Step 11: Select the installation directory (Default is C:\SERVER.40).

    Step 12: Select Country codes information  to continue.

    Step 13: Select Filename Format (Default is DOS format).

    Step 14: Select "No Startup Commands".

    Step 15: Make a selection at "Do you want AUTOEXEC.BAT to load SERVER.EXE?"

    Step 16: System scans for available drivers.

    Step 17: Press  to select an unlisted driver.

    Step 18: Put diskette into drive A which contains PM14NW40.DSK;
    "Netware v4.xx DPT PCI SCSI driver"

    Step 19: Install switches to Server Console and loads drivers

    Step 20: Select "Continue with installation".

    Step 21: Create Netware disk partition.

    Step 22: Choose "Automatically".

    Step 23: Select  to save.

    Step 24: Choose "YES" to confirm save.

    Step 25: Insert Netware License diskette as requested.

    Step 26: Install system and public files.

    Step 27: Choose  to exit the installation program.

    Step 28: Bring down the Server by typing
    	DOWN

    Step 29: Exit to DOS by typing
    	EXIT

    Step 30: Remove SCSI device drivers from CONFIG.SYS and AUTOEXEC.BAT to avoid
    conflicts with Netware SCSI drivers.

    Step 31: Reset the system by pressing the  button.

    Step 32: Type
    	CD\SERVER.40.

    Step 33: Type
    	SERVER
    As Novell Netware loads, the PM14NW40.DSK drivers will load and display status
    messages.  After successfully loading, Volume SYS will be mounted.

    Step 34: Type Load install to start the Novell Netware installation program.
    Continue with the installation by adding Network drivers and creating the
    AUTOEXEC.NCF and STARTUP.NCF files.

    Step 35: When complete, DOWN the Server, EXIT to DOS, and reboot.  The Server
    should come up without errors.
